Pokalon still available

Pokalon polycarbonate film, which was offered by Lofo High Tech Films GmbH in the past, will be sold by Dr. Dietrich Müller GmbH may be available.

The material Pokalon, which was offered by Lofo High Tech Films GmbH in the past, will in future be sold by Dr. Dietrich Müller GmbH may be available.
POKALON® is made of polycarbonate (PC). A particularly heat-resistant PC is used for some special types. The product portfolio includes unstretched films in the thickness range from 6 mm to 125 mm; other thicknesses can be offered on request.

MECHANICAL PROPERTIES of Pokalon

POKALON has high rigidity and strength and is impact resistant over a wide temperature range. The film has a very high tear and tear strength and is resistant to breakage and shattering. POKALON can be deep drawn very well.

OPTICAL CHARACTERISTICS of Pokalon

POKALON – polycarbonate foils are available with a glossy, one-sided or both-sided matt surface structure. The glossy finishes are highly transparent and have high optical purity (free of specks and gels) and low birefringence.

ELECTRICAL CHARACTERISTICS of Pokalon

The dielectric loss factor of POKALON is low and, like the dielectric constant (relative permittivity), shows a low temperature dependence. The insulating properties are very good even at higher temperatures and the dielectric strength of the thin films is excellent. Due to the very low moisture absorption, the electrical properties are hardly affected by the moisture content of the material.

CHEMICAL PROPERTIES of Pokalon

POKALON is resistant to oils, fats, petrol, aliphatic hydrocarbons and most alcohols. POKALON is not resistant to chlorinated hydrocarbons, ketones, aromatic solvents and bases. With these substances, the film is attacked or dissolves.

WATER ABSORPTION from Pokalon

Due to the very low moisture absorption of approx. 0,2%, the film remains dimensionally stable so that the film properties are hardly affected.

FURTHER PROCESSING by Pokalon

POKALON can be glued well with selected solvents, solvent-based adhesives and dispersion adhesives as well as with the hot-melt process. Welding is possible with the heat pulse process, ultrasound or high frequency, among other things.

PRINT and coating by Pokalon

POKALON can be printed with many printing processes. The film is easy to write on with dissolving pens and inks. The matt film side can be wiped off and is smudge-proof. The film can be coated using standard high-vacuum processes.
