The performance of silicone rubber, particularly Room Temperature Vulcanizing (RTV) systems, is intrinsically linked to the quality and properties of its base polymer. For manufacturers of RTV silicone rubber, selecting the right raw materials is crucial for achieving desired elasticity, durability, and processing characteristics. Hydroxy Terminated Polydimethylsiloxane (CAS 70131-67-8), often referred to as silanol-terminated PDMS, stands out as a foundational component in this critical area. As a leading chemical supplier, we delve into why this specific silicone fluid is indispensable for modern silicone rubber production.

Hydroxy Terminated Polydimethylsiloxane is characterized by its reactive silanol (Si-OH) end groups. These functional groups are the key to its role as a base polymer. During the RTV curing process, these hydroxyl groups react with crosslinking agents, typically in the presence of a catalyst, to form a three-dimensional network. This crosslinking is what transforms the liquid polymer into a flexible, elastomeric solid. The viscosity, molecular weight, and purity of the Hydroxy Terminated PDMS directly influence the rheology of the uncured compound and the mechanical properties of the cured rubber, such as tensile strength, elongation, and tear resistance.

Procurement managers and R&D scientists looking to buy Hydroxy Terminated Polydimethylsiloxane for their silicone rubber formulations are seeking reliability and performance. Our company, a prominent manufacturer of silanol terminated PDMS, ensures that our product meets the highest standards. The consistent hydroxyl content and controlled viscosity of our material, identified by CAS 70131-67-8, are vital for predictable curing behavior and optimal final product properties.
