HY-SEMMAS Mono-Methacrylate Terminated Polysiloxane
HY-SEMMAS mono-methacrylate terminated polydimethylsiloxane is a modified silicone material that combines the flexibility and heat resistance of PDMS with the curability of methacrylate groups, enabling crosslinking through free-radical polymerization.
Product Features
Excellent oxidation resistance, high/low temperature resistance and weatherability.
Excellent water resistance and stain resistance with lubricity.
Good compatibility with metal, plastic, rubber and other substrates.
Customizable mono- or di-end-capped structures and molecular weight distribution from 1000 to 100000.
Mainly used in contact lens and other optical/medical material applications.
