Application:
1. Hydrosilylation of basic raw materials it was used all kinds of end-reactive linear modified silicone.
2. It's the key intermediate of the block copolymerization .
3. Can be used as plus liquid silicone rubber's chain extender, plus hot forming curing agent 's crosslinker, improve product's elongation at break, increase in toughness, reduced the hardness.
4. The beginning of raw material of the organic polymer modified materials, commonly used in resin's modified reaction.
5. moisture-proof are as same as 202,203.
