For professionals in the chemical and manufacturing sectors, a thorough understanding of product specifications and chemical properties is fundamental to successful procurement and application. This is especially true for versatile materials like Polydimethylsiloxane (PDMS), including its important variant, Silanol Terminated Polydimethylsiloxane (CAS 70131-67-8). As a dedicated chemical supplier, we provide critical information to empower informed purchasing decisions.

Silanol Terminated Polydimethylsiloxane is recognized for its distinctive chemical characteristics. Typically appearing as a colorless transparent liquid, its purity often exceeds 99.5%, making it suitable for high-end applications. Key specifications include a low melting point (<-60°C), indicating its liquid state across a wide temperature range, and a density around 0.98 g/mL. The presence of terminal silanol (Si-OH) groups is its defining feature, enabling it to participate in condensation reactions. This reactivity is crucial for its use as a precursor in silicone polymer synthesis and as a crosslinking agent in RTV silicone formulations.

When potential buyers, such as procurement managers or R&D scientists, search for information, they often use terms like 'PDMS chemical properties,' 'silanol terminated polydimethylsiloxane specifications,' 'CAS 70131-67-8 data sheet,' or 'where to buy high purity silicone fluid.' These queries reflect a need for precise technical details that influence purchasing decisions. Understanding these specifications allows users to predict performance, ensure compatibility with other materials, and optimize their formulation processes.

As a manufacturer and supplier, we are committed to providing comprehensive and accurate product data. Our Silanol Terminated Polydimethylsiloxane is produced under strict quality controls, ensuring that it meets the listed specifications consistently. By offering this transparency, we help our clients confidently select the right materials, avoid costly errors, and achieve superior results in their applications, whether in textile finishing, coatings, or advanced material synthesis.
