SILKLONThermoplastic polyurethane elastomer film
Silklon is a film extruded from thermoplastic polyurethane elastomer resin (TPU),and it has both rubber flexibility and plastic strength / hardness. We have been manufacturing and selling it since 1989. We can offer films with thickness of 8 μm to 800 μm by inflation or T die process film formation which can also film different kinds of three layers. If necessary, we will also handle separators (PE, PET, paper etc) and please consult with us for customization according to your request.
