Liquid silicone rubbers of the SILPURAN 6600 series are paste-like, easily-pigmentable two- component compounds with short curing times. Their vulcanizates are noted for their high transparency and excellent mechanical and electrical properties.Compared to the SILPURAN 6000 series the coefficient of friction of a post-cured article made of SILPURAN 6600 is reduces by 50-70%. SILPURAN 6600/40 A/B is designed for medical applications in compliance with the WACKER SILICONES HEALTH CARE POLICY including imolantation for ＜30 days. 

Specific features
