Procurement specialists and product formulators are constantly on the lookout for high-performance materials that can enhance their product lines. Hydroxyl Silicone Oil, identified by CAS 70131-67-8, also known as Hydroxy Terminated Polydimethylsiloxane or OH Polymer, is one such essential chemical. As a leading manufacturer and supplier based in China, we offer this critical material and provide insights into why sourcing it from us is a strategic choice.

Understanding Hydroxyl Silicone Oil (CAS 70131-67-8)

This organosilicon compound is characterized by the presence of terminal hydroxyl (-OH) functional groups. This molecular architecture grants it unique reactivity, making it an excellent intermediate for synthesizing more complex silicone polymers and elastomers. Its properties include a colorless, transparent liquid appearance, high flash point, low freezing point, and remarkable stability across a wide temperature range (-50°C to +250°C). These attributes are vital for applications where material reliability is paramount, driving the need to buy from quality manufacturers.

Key Specifications and Performance Benefits for Buyers

When evaluating suppliers for CAS 70131-67-8, several specifications are critical:

  • Viscosity: Available in various grades, with common viscosities ranging from tens to hundreds of thousands of centistokes, allowing for tailored formulation use.
  • OH Content: The percentage of terminal hydroxyl groups influences reactivity, with higher content generally indicating greater cross-linking potential.
  • Purity: High purity ensures consistent performance and predictability in downstream applications. We guarantee >99.9% purity for our product.
  • Appearance: Consistently colorless and transparent, indicating a well-controlled manufacturing process.

The benefits of using this material include excellent electrical insulation, superior water repellency, and robust resistance to aging and weathering, making it a preferred choice for demanding applications.

Diverse Applications Driving Industrial Demand

The versatility of Hydroxyl Silicone Oil makes it indispensable in numerous industries:

  • Silicone Rubber Industry: It serves as a primary raw material for producing RTV (Room Temperature Vulcanizing) silicone rubbers, sealants, and adhesives, which are vital in construction, automotive, and electronics.
  • Textile Auxiliaries: Used as a finishing agent to improve fabric softness, smoothness, and drape.
  • Plastic and Rubber Auxiliaries: Acts as a mold release agent and processing aid, enhancing manufacturing efficiency.
