CX-350&351 Low Hydrogen Silicone

  • Colorless viscous transparent liquid
  • Excellent water repellency and moisture resistance.
  • It is used in the fields of electronics, electrical, textiles, to play a role in waterproof, insulation, corrosion resistance or softness.


This product is formulated from imported raw materials. The hydrogen-containing active groups in the molecular chain are evenly distributed. It can react with other active groups, double bond polymers and other organic compounds. It is a thermally conductive silicone resin gel,and can be use as the basic raw material of foaming agent, modified silicone oil and other products.


  • Colorless viscous transparent liquid
  • As a chain extender for addition type liquid silicone rubber, and a crosslinker for addition type heat vulcanized silicone rubber.
  • The basic raw material of organic polymer modified materials.


  • Better mechanical properties and excellent thermal conductivity.
  • Improve the elongation at break of the product, increase the toughness and reduce the hardness.
  • Excellent water repellency and moisture resistance.
