VINYL TERMINATED POLYDIMETHYLSILOXANE

SILSOURCE™ VF-65000

Product Description

Vinyl terminated polydimethylsiloxane is a type of siloxane polymer, where each silicon atom is bonded to two methyl groups (-CH₃) and one vinyl group (-CH=CH₂) at the terminal positions. This structure allows the polymer to undergo crosslinking reactions, making it highly versatile for applications requiring silicone elastomers, coatings, and adhesives. The vinyl groups at the ends of the polymer chain facilitate easy curing or vulcanization, particularly in applications where further chemical bonding or reaction is required.
