liner

Under one cover is the material that covers the adhesive. Especially necessary when the adhesive too much on his own carrier would stick. Normally siliconised paper. There are also e.g. PE or PET film available. For double-sided adhesive tape is always a double-sided separation situation repellent used.
 

acrylic adhesive

Powerful adhesive polymer for almost all applications. It is from aqueous dispersions or solvent processing systems. Very good aging resistance and resistance to UV radiation. Most good solvent resistance, therefore good for electrical applications (watering) suitable.

adhesion

Sticky effect between a fixed border area and a second phase consisting of either individual particles, molecules, or powders or droplets from a continuous liquid or solid film can exist.

aging resistance

Kleber change over a longer storage time their properties. That does not always within the meaning of a deterioration done. Our adhesives are at least 6-12 months if properly stored (cool and dry) without sacrificing the properties of shelf life. Most adhesive tapes are also after several years of storage is still fully usable.

initial adhesion

C denotes the adhesion ( "Tack") of an adhesive. The C-adhesion can also be used for low-adhesives very high. However, there is no direct link between the immediate adhesion and lasting adhesion.
 

coating Process

1) Direct coating:
This is the glue on the foil and then the door "gegengewalzt." The advantage here is faster processing time, usually 95% of the films coated with this procedure
2) transfer coating:
First, the coverage and then coated the film gegengewalzt. This creates a slightly longer lead time, as an educational bands on the slide must be avoided.
 

CTI comperative tracking index

Claim in relation to the stocks of a substance isolation, in humid and polluted environment of a voltage difference to resist. Measuring principle: A insulation material, two electrodes attached between this one and saline geträufelt. The voltage generates a current flow.

corona treatment 

Most plastics have a nonpolar, electrically insulating well and surface water. It is poorly wettable by printing inks, solvents, aqueous Kunststoffdispersionen, glues or bonding agents. This is particularly true for polyethylene, polypropylene and polyester films. The printing of such plastics (film or physical body) or its further processing by laminating or coating is therefore not possible at all. The inks were not liable for the manufacturing of laminated sheet delamination would occur. It helps you through the corona treatment, the most commonly used form of surface treatment. Alternative methods would be the flashpoint treatment, the fluorination and the plasma treatment. The aim of all these methods is to increase the polarity of the surface, thereby wetting and chemical affinity significantly improved.

density (engl. density)

Included are dispersions of polymers such as natural and synthetic rubber, both of synthetic resins and plastics, such as Polymers, and Polycondensates Polyadditionsverbindungen. There are Primärdispersionen in which the polymerization of the base monomers directly in the liquid phase (Suspensionspolymerisation or emulsion polymerisation, such as vinyl or acrylates) and Sekundärdipsersionen in which prefabricated polymers in a second step will be dispersed (eg polymer dispersion of polyisobutene, silicone resins). Very little impact on the environment with solvents during production. But mostly no high temperature stress and danger of corrosion effect when used in electrical engineering. Often used in mass-label area.

electrolytic corrosion

Describes the corrosion effect of a tape onto another material. To measure the effect of corrosion is the tape on a Prüffolie brass glued and while the influence of voltage, heat and humidity, so under difficult conditions, examined. As a measure of Prüffolie corrosion of the material is characteristic assigned. The positive film receives values of A (no change) on AT, A / B to B (strong red color) and the negative slide values of 1 (no change) over 1.2, 1.4, .. . 2, 3 to 4 (major discoloration). Factors apply to 1.4 in electrical engineering as a non-corrosive.

flat crepe paper

Here: Special kraft paper with mild Kreppung (elasticity, Auspolsterung). Our flat crepe is specially inked, so it is in the transformer isolation technique as a simple means can be used.

flat primer

If sufficient glue liability (for example, EPDM, PP or PE) can be done with the use of primers much better adhesion forces reach. Primers are usually very thin to apply and form an almost invisible film on the surface to stick together..

hanging time

Here are the films "suspended" so that bubbles may occur with time back to form.

electric insulation classes

Classification of adhesive tapes in the electrical sector, in accordance with their continuous use temperature rating.
The individual classes (classes heat) mean:

Class E a permanent temperature to 120 Â ° C
Class B, a permanent temperature to 130 Â ° C
Class F a permanent temperature to 155 Â ° C
Class H a permanent temperature to 180 Â ° C
Isolation of the individual classes are assigned to different films. The best known are polyester (B) and KaptonO (H)

insulation

The property of an adhesive tape, an electrical separation between two ladders to generate electricity. Common: separation between primary and secondary of a transformer.

rubber-solvent adhesive

Glue made from natural or synthetic rubber. The gluten in general have a high adhesion and very good to shear.

adhesion strength / peel strength

Even adhesion. Is that force, with a tape from a surface can be deducted. Is usually measured as follows: On a standard steel surface (or glass) is a 10 mm (N/10mm) or 25 mm (N/25mm) wide tape pasted. After a certain dwell time (immediately, 20 minutes, 24 hours), the tape at an angle of 180 degrees deducted. This is the required force measured (10N ~ 1kg).

cohesion

Name for the chemical bond by real zwischenmolekularen or forces cohesiveness of causing substances. The cohesion can be considered as a special case of adhesion considered in the same particles stick together. Cohesion forces are inside the material effectively. The cohesion in solids than in liquids, it causes the inner strength of the adhesives. A measure of cohesion is the shear a sticker.

corrosion

From Latin: corrodere = zernagen derived name "for the reaction of a metallic material with its environment, a measurable change in the material and cause a deterioration of the function of a metallic component can lead." You can also define corrosion than the outgoing surface, through accidental chemical or electrochemical attack caused, and adverse quality of a material change. But also: destruction of insulation with Spannungsbeaufschlagung. A measure of the destruction by voltage, the CTI value.

rolling ball tack test

Tacks determination of a sticker. It runs a steel sphere a sloping surface down into the adhesive coating inside. Determined the route until the ball comes to a standstill. The ball test is measured in centimeters. The test is inaccurate because of the controversial results.

storage

Modern adhesives have a large bearing resistance - ie they do not change their properties if properly stored. Is an optimal storage in a dry, dark room at around 18-22 ° C. Tapes are then often lagerbar years.

micron

The unit described in the tapes thickness of the film makers or the adhesive. One micron = 1 thousandth of a millimeter (0001 mm). A human hair has a diameter of about 40 microns. The most common insulation polyester film is 23 microns (0023 mm) thick.

N

Symbol for Newton. Simplified one can say that 10 N to a force of 1 kg corresponds. The adhesive or tearing example in N / mm measured.
Wetting

 

Opak (engl. opaque)

Largely or completely opaque film. Unlike translucency (translucent) or transparent.

polyethylene

Abbreviation for polyethylene. Polyethylene is among the polyolefins, and has even at low thicknesses a high tensile strength. The film is an LD (low density)-PE soft and nestles well surfaces. Often as effective protective surface in use. UV and low temperature resistance.

polyester film

Against high temperatures, alkalis, acids, oils and various solvents very resistant film with very good strength. Most widely used in electrical insulation film sector and a tape. Affordable and still best physico-chemical properties. Standard strengths: 23 micron, 36 micron, 50 micron, 100 micron, 150 micron, 190 micron and 250 microns.

polyimide film

Plastic film with high temperature resistance. Generally considered KaptonO (trade name of the company, Du Pont) known. Polyimide films can be up around 350 ° C and offers the best mechanical and electrical properties. The brown-lucent film is relatively expensive and is often used in the electrical industry as a high insulation used.

OPP-film

Very convenient foil mass, mostly for the packaging industry. Polypropylene belongs to the PE as polyolefins. Good resistance to acids, alkalis and solvents, good Einreißfestigkeit, low temperature resistance.

polyurethane

PU is the abbreviation for polyurethane. For double-sided adhesive tapes for use in noise and abrasion protection. In the electrical industry hardly used.

vinyl foils

PVC stands for polyvinyl chloride. Very UV-stable foil. As a soft PVC film in Isolierbereich in use. Low temperature resistance and plasticizer migration possibly injury to the subsoil.

tensile strength

Tensile strength (release value) (Engl. tensile strength)
Force which is necessary to prevent e.g. 25 mm wide strip of foil (adhesive is without relevance to the trial) to rip. To determine a film strips in a tensile tester with a defined and fixed speed pulled apart. The result is expressed in N / mm.

shear adhesion, shear resistance

The shear describes in particular the inner strength of the adhesive. It distinguishes between the static and dynamic shear shear. The measurement methods differ as follows: For the static shear is a nearly vertical steel plate a 25 mm x 25 mm large area taped and pasted with a certain mass (0.5 kg, 1 kg and 2 kg) by train charged down. This is the time in hours, until the bonding abschert. When the dynamic shear is described bonding burdened by a tensile tester and the force (Newton), which is needed to address bonding glues ermittelt.Scherfeste Grants are ideal to train loaded flat materials together.

silicoizing

Treatment of surfaces in order to make it kleberabweisend, eg Paper or foil. The surfaces are very smooth and only with Polysiloxankleber glueability. These stickers may therefore not be covered siliconised paper, but it will fluorsilikonisierte films.

silicone rubber adhesive

Polysiloxankleber have excellent properties in terms of heat and Kälteresitenz. The glue can usually up to 300 Â ° C and -50 C ° Â used. Do you have a good grip on silicone papers / silicone profiles. On other surfaces (such as metal surfaces) even after heat stress residue free again to remove.

splice

Flick receive one or splice. In the paper and film industry refers to the point where the two tracks together are material. Especially silicone papers can be used only with polysiloxane-adhesive tapes are spliced.

telescoping

Error picture tapes. Due to stramme winding the soft layers of tape for funnel-shaped side. The tape teleskopiert so from the original width role beyond. This error image can also arise if adhesive tapes made of materials that can absorb water (eg NomexO), to be stored moist.
 

temperature

Operating temperature for adhesive tapes. In electrical engineering from the warmth of a class (usual: 130 ° C max. 180 ° C). Best combination of stickiness (Instant liability) at room temperature and adhesion. At very low temperatures possibly fracture risk of acrylate adhesives and rubber when bending loads. 

Tempern

It passes through the slide in the coating process heaters, so that the plasticizer from the film not in the glue wandernâ â.

carrier, backing

The carrier is the material on which the glue is applied. So normally films, fabric, fleece or metal sheeting.

liner

Under a separation situation is the material that covers the adhesive. Normally siliconised paper. There are also e.g. PE or PET film available. For double-sided adhesive tape is always a double-sided separation location used. Separation location = coverage

ultra-violet rays

Rich energy electromagnetic radiation with a wavelength of visible light below, (l = 400 - 10 nm). UV radiation is contained in daylight and during many rubber adhesives for destruction. This process is dependent on the radiation intensity. Tapes must therefore be stored dark. Widespread resistance to UV radiation are acrylic-on adhesive tapes. So it comes to the application to which adhesive can be used.

laminate

Combination of two or more layers of folienartigen materials. Typically, the reunification of the positive characteristics (such as laminated glass and polyester fabric: tearing through glass fabric, tension strength by polyester film) of the laminate partner. The adhesive laminate is usually no more solvable.

cross-linking

Adhesives are made from coated solutions or dispersions. The network polymers dissolved in evaporating the solvent molecules into larger organizations. You can with the degree of networking and the stickiness of the chemical and thermal stability control. The networking can be thermosetting adhesives by subsequent injection temperature (about 100 ° C at CMC) to be strengthened. The adhesive is then chemically stable.

Viskosität

Viscosity of the adhesive. The higher the throughput, the higher the viscosity.

Wärmehärtend (engl. thermosetting)

Tapes with thermosetting adhesive coatings, as usual, can be used at room temperature. Through a heat (over 100 ° C at CMC) is the resistance to solvents (Tränkmittel in the transformer industry) improved.
