purpose
- hydrosilylation of basic raw materials it was used all kinds of end-reactive linear modified silicone.
- its the key intermediate of the block copolymerization .
- can be used as plus liquid silicone rubbers chain extender, plus hot forming curing agent s crosslinker, improve products elongation at break, increase in toughness, reduced the hardness.
- the beginning of raw material of the organic polymer modified materials, commonly used in resins modified reaction.
- moisture-proof
