TERMINAL HYDROGEN SILICONE
TERMINAL HYDROGEN SILICONE

H-terminated PDMS is the short name of hydrogen terminated polydimethylsiloxane. It belongs to hydrogen terminated linear silicone and not to hydrogen branched silicone.

In the preparation of H-terminated PDMS, the molecular weight and hydrogen content are different with the different ratio of sealing agent to D4. We mainly have 8 types.
