Two-part, white silicone system designed for use with injection molding equipment
Cures with heat via addition-cure chemistry
1:1 Mix Ratio (Part A: Part B)
High tear strength
Designed to resist blocking and rehealing that otherwise might be induced by the radiation sterilization of molded parts.
APPLICATION
For the injection molding of parts requiring a material with a medium durometer including: molded rubber stoppers, gaskets, seals, valves, o-rings and other precision parts
Suitable for over-molding applications
Can be used with NuSil's Healthcare color masterbatches for applications requiring colored silicones
