The spiraling technique consists in coupling a series of adhesive-coated strips, winding them around a mandrel, obtaining a tubular whose electrical, thermal, impregnation and mechanical characteristics are the sum of the ones of each layer.
Politubes uses only the best high quality insulating films UL approved available from the global leading manufacturers.
Spiral wound tubing offer insulation class between thermal class A – 105°C, B – 130°C, class F – 155°C, class H – 180°C till class C > 400°C.
Despite tubes very thin thickness, spiral wound tubes can offer a dielectric strength between 3 kV/mm till 300 kV/mm with reference to the standard: ASTM D-149.
Politubes adhesives, carefully selected during our forty years of experience, comply with all REACH and RoHS most updated regulations.
Spiral wound tubes are compatible with resins and chemicals used in the electromechanical industry and ensure that the original properties of the films used are fully maintained.
