DESCRIPTION:
1. This product is the end vinyl polydimethylsiloxane, active
intermediate material.
2. The product has common
performance of methyl silicone oil.
3. Two ends of vinyl is too active to react with hydrogen
silicone with catalyst, also can participate in a variety of other
reactions.
4. it has better intermiscibility with organic material comparing
to methyl silicone oil, easy to compatibility with other organic
materials.
5. For containing lively double bond, easy to have reaction with
organic material such as polyurethane, acrylic acid etc.
CAS No.: 68083-19-2
STRUCTURAL FORMULA:
APPLICATION:
1. Used as basic raw material
of high temperature vulcanizing silicone rubber (HTV), to enhance
the hardness and strength of silicone rubber.
2. For the production of liquid silicone rubber, it’s the main
material of injection molding silicone rubber.
3. This product will be reacted with organic material such as
polyurethane, acrylic acid etc., to produce new material that have better
performance (weathering resistance, ageing resistance, anti-UV, reinforcing and
toughening etc.), widely used in the plastic,resin,paint, and coatings
modified.
