Composite films

Electrical insulation of thermal class B up to 130 ° C according to IEC 626-3 sheet 100-102-112.

Polipress is a composite of pressboard and polyester film. The quality of "S" refers to the execution of the composite polyester / pressboard, the term "D" stands for the 3X Composite material / Polyester / pressboard. The film thickness of the polyester film is 25μ or 50μ and pressboard thickness is variable depending on the thickness of the overall assembly.

Thanks to the combination with polyester pressboard receives a much higher tensile strength with good flexibility and dielectric properties.

Politrix is an advancement for Polipress D. In Politrix the strength of the force the paper web remains the same, while the inner layer of polyester is changing.

Characterized a higher mechanical and electrical effect is achieved. The good Tränkmittelaufnahme through the kraft paper remains. The sometimes problematic moisture absorption of pressboard and the resulting curl is avoided.

In order to meet the conditions for WKL "F", the polyester film laminated on both sides with Nomex *. For this purpose, an adhesive temperature class "H" is used. Polimex is a composite of Mylar A with Nomex by DuPont.

Electrical insulation of thermal class B / F to 130 ° C / 155 ° C according to IEC 626-3 sheet 500

POLIVLIES DMD is a laminate non-woven polyester fabric. In the manufacture of the laminate a high temperature resistant adhesive system is used which includes the film and protects. The impregnation is 70%. The fleece used by POLIFIBRA is suitable for high temperatures and has a very good absorbency. This is important for all of uniform absorption of impregnating agents. By impregnation with a suitable resin, the insulation class F can be achieved.

Electrical insulation of thermal class F (155 ° C) -According to IEC 626-3 sheet 500th

Thermef is the logical development of DMD.
With the same base materials (fleece / polyester / fleece) is here through a wholly owned coating with a resin of thermal class H (180 ° C) for this product heat class F (155 ° C) erreicht.Thermef is tested according to ASTM D 1830 been. The coating is applied very evenly and at high temperatures. To 180 ° C melting is excluded. Thermef is highly compatible with the conventional impregnating resins. For Thermef we use a heat-stabilized polyester film to reduce the shrinkage at 155 ° C.
