Tetravinyltetramethylcyclotetrasiloxane

Synthesis and Properties of Cross-Linkable Polysiloxane Using a Super base Catalyst

1,3-Divinyltetramethyldisiloxane (D6210) 1,3,5,7-Tetravinyltetramethylcyclotetrasiloxane (PS925; aka Cyclic vinylmethylsiloxanes) Polysiloxanes are widely used in the semiconductor industry as encapsulation materials. These materials have high electrical insulation characteristics and are highly transparent to solar radiation, as well as having a high degree of both chemical inertness and thermal stability leading to a large range of operational temperatures and…
