For procurement managers and R&D scientists seeking versatile chemical solutions, Hydroxyl Terminated Silicone Oil, also known as OH Polymer or Silanol Terminated Polydimethylsiloxane (CAS No. 70131-67-8), represents a powerful tool. This functional silicone fluid acts as an indispensable chemical auxiliary agent in a myriad of industrial applications, from rubber manufacturing to textile finishing. As a leading manufacturer and supplier based in China, we offer a reliable source for this high-performance material, emphasizing quality, customization, and competitive pricing.

The Broad Spectrum of OH Polymer's Utility

The defining feature of OH Polymer is the presence of reactive hydroxyl (-OH) groups at its molecular ends. This characteristic allows it to participate in various chemical reactions and surface modifications, making it a highly adaptable auxiliary agent:

  • Chemical Reactions: It serves as a reactive intermediate, enabling the synthesis of more complex silicone polymers, resins, and crosslinked networks, particularly in RTV silicone sealants and rubbers.
  • Surface Modification: The hydroxyl groups can interact with various substrates, improving adhesion, providing hydrophobicity, or acting as compatibilizers.
  • Rheology Modification: In formulations, it can influence viscosity, flow properties, and thixotropy.
  • Lubrication and Softening: It imparts excellent lubricating and softening properties, especially valuable in textile and leather treatments.

Industries Relying on OH Polymer as an Auxiliary Agent

As a trusted supplier, we see demand for OH Polymer across a wide range of sectors:

  • Rubber Auxiliary Agents: A primary use is in the silicone rubber industry, where it acts as a base polymer or modifier for RTV and other silicone elastomers. Manufacturers actively seek bulk OH Polymer for their compounding needs.
  • Coating Auxiliary Agents: Incorporated into paints and coatings to improve flexibility, weathering resistance, and surface properties.
  • Plastic Auxiliary Agents: Used to enhance the processability and surface finish of plastics.
  • Textile Auxiliary Agents: Provides softening, lubrication, and improves the feel and sewability of fabrics.
  • Electronic Chemicals: Utilized for insulation, potting, and encapsulation due to its dielectric strength and thermal stability.
  • Water Treatment Chemicals: Employed in certain formulations for its surface-active properties or as a component in specialty treatments.
