CX-305B Single-ended Vinyl Silicone

  • Fast heat cure
  • Soft and smooth, suitable for a variety of cosmetic formulations;
  • It is widely used in electronic and electrical potting, heat conduction and heat dissipation, sealing filling, cosmetics and other industries.


CX-305B is a non-toxic, odorless, transparent oily substance, formulated from imported raw materials, with a vinyl active group at one end of the molecular chain, which can react with other active groups, hydrogen-containing groups and other organic compounds. Under the catalysis of peroxy compounds, a silicone elastomer is formed, which is used to adjust the viscosity of silica gel, or to make liquid silicone rubber with different hardness and mechanical properties. No other low molecules are released during the reaction. It is the basic material for the production of addition-molded liquid silicone rubber, silicone gel and other products.
