World class silicones for worldwide solutions

Hydride Siloxanes

See Product List


Our hydride functional siloxanes are divided into crosslinkers and chain extenders, both of which not only influence the viscosity of the formulation, they are also responsible for the desired mechanical properties. While the crosslinker crosslinks the formulation and chain extenders lengthen the chain and thus give the elastomer the desired hardness and elongation.

CHT also offers these two types in combination. The flash point is regularly >65 °C and the density is 0.97 g/mol. The product is a colourless liquid.


  • Modifies Shore hardness
  • Increases tensile strength
  • Improves surface properties
  • Supports formulations with high elongation at break
  • Low D4; D5; D6 content

Finding the right silicone for your application is not limited to CHT’s product portfolio. Our technical team will partner with you to either modify specifications in a current product or custom formulate a new one to meet your exact requirements.
