The production of high-performance silicone rubber is a sophisticated process that relies on precisely engineered raw materials. Among these, Vinyl Terminated Polydimethylsiloxane (PDMS), identified by CAS No. 68083-19-2, stands out as a foundational component. This specialty silicone fluid is not merely an additive; it is the primary building block that enables silicone rubber to achieve its characteristic flexibility, thermal stability, and resilience.

Vinyl Terminated Polydimethylsiloxane acts as the base polymer in the formulation of both High-Temperature Vulcanizing (HTV) and Liquid Silicone Rubber (LSR). In these systems, the polymer chains are essentially long chains of polydimethylsiloxane with vinyl groups attached at the ends. These vinyl groups are the reactive sites that facilitate the cross-linking process, commonly known as vulcanization or curing. This reaction, usually catalyzed by platinum compounds, links the PDMS chains together, transforming the liquid or viscous polymer into a solid, elastomeric material.

The specific properties of the final silicone rubber product are heavily influenced by the characteristics of the PDMS used. Variations in viscosity and vinyl content allow manufacturers to control key performance attributes such as tensile strength, elongation at break, tear resistance, and hardness. For instance, a higher vinyl content can lead to faster cure rates and a denser cross-linked network, resulting in a stiffer rubber. Conversely, lower vinyl content PDMS can yield more flexible elastomers.
