Vinyl terminated polydimethylsiloxane Usage And Synthesis

Physical form

Divinyl functional reactive silicone fluid.

Features and Benefits

Polymerized product provides non-corrosive shield against moisture, dirt and contaminates for electrical components. Polymer may be heat or room temperature cured. Polymerization produces no volatile gases.

Description

Vinyl-terminated dimethylpolysiloxanes (Vinyl terminated polydimethylsiloxane) are available in various viscosities. Vinyl terminated silicone fluid is a base polymer for addition-curing RVT-2k (room temperature vulcanizing two components), LSR (liquid silicone rubber) silicone rubber. The terminalvinyl groups participate in the vulcanization reaction with Crosslinking agents in the presence of Catalysts.

Uses

Mold-making elastomers and encapsulants and sealants for electronic components. Vinyl terminated polymers are most often employed in 2-part addition cure silicone elastomers.
