In the realm of specialty chemicals, Hydroxy Terminated Polydimethylsiloxane (CAS 70131-67-8), also known as OH Polymer or Hydroxyl Silicone Oil, plays a pivotal role as a versatile intermediate. Its unique hydroxyl-terminated structure enables it to be a foundational component in numerous advanced formulations across diverse industries. As a dedicated manufacturer and supplier in China, we specialize in producing this essential material and highlight its significance for R&D scientists and procurement managers.

Understanding the Functional Advantage of OH Polymer

The defining feature of CAS 70131-67-8 is the presence of reactive hydroxyl groups at the end of its polymer chains. These functional groups allow the molecule to participate in various chemical reactions, most notably condensation polymerization. This reactivity is what makes it an indispensable ingredient for formulating:

  • RTV Silicone Sealants and Adhesives: The hydroxyl groups react with cross-linking agents (like silanes) to form durable, flexible, and weather-resistant silicone elastomers. These are crucial for sealing applications in construction, automotive, and electronics.
  • Silicone Rubber Compounds: It serves as a base polymer for many silicone rubber formulations, contributing to their excellent thermal stability, flexibility, and electrical insulation properties.
  • Surface Treatment Agents: Its ability to bond with various substrates makes it an effective agent for imparting hydrophobicity, smoothness, and release properties to textiles, leather, paper, and fillers.

Impact Across Industries

The integration of Hydroxy Terminated Polydimethylsiloxane into formulations translates to tangible improvements in end-products:

  • Construction: Enhances the performance of sealants, providing long-lasting protection against environmental factors. Procurement teams often buy this for its reliability in high-performance construction materials.
  • Electronics: Its excellent dielectric properties and thermal stability are leveraged in potting compounds and encapsulants, protecting sensitive electronic components.
  • Textiles: Used as a softener and finishing agent, improving the feel and handling of fabrics. Manufacturers seek this chemical auxiliary for its efficacy.
  • Automotive: Contributes to the durability and performance of sealants, gaskets, and coatings used in vehicles.
