Everything you need to know about our products and company
Vinyl Terminated Silicone Fluid (VT-SF) is a specialized organosilicon compound featuring reactive vinyl groups (-CH=CH₂) at both ends of the polydimethylsiloxane molecular chain. This unique chemical structure provides exceptional versatility while raising important questions about its safety profile. As a key intermediate in silicone elastomers, sealants, and high-performance materials, understanding its toxicity is crucial for industrial applications.
The toxicity profile of Vinyl Terminated Silicone Fluid varies significantly based on formulation, purity, and application context. When properly manufactured and handled according to industry standards, high-purity VT-SF demonstrates low toxicity levels suitable for numerous industrial and even medical applications .
According to safety data sheets, pure Vinyl Terminated Polydimethylsiloxane (CAS 68083-19-2) carries a GHS07 warning with specific hazard statements including H302 (Harmful if swallowed), H315 (Causes skin irritation), H319 (Causes serious eye irritation), and H335 (May cause respiratory irritation) . These classifications primarily apply to concentrated forms, and appropriate handling precautions are necessary during industrial processing.
The flash point of VT-SF exceeds 110°C, indicating relatively low flammability risk under normal conditions . This thermal stability contributes to its safety profile compared to more volatile organic compounds. Material Safety Data Sheets from specific formulations classify vinyl terminated polysiloxane compounds as non-hazardous and non-flammable with a health rating of 0 according to NFPA standards .
Global standards organizations have established rigorous frameworks for VT-SF safety and quality:
Leading manufacturers like Biyuan implement these standards throughout their production processes, conducting rigorous toxicity testing to ensure customer safety and regulatory compliance across industries.
Medical-grade Vinyl Terminated Silicone Fluid demonstrates excellent biocompatibility when properly formulated and purified. With ISO 10993 certification, these fluids are suitable for wearable medical devices, implants, and diagnostic equipment where direct body contact occurs . The material’s stability allows it to withstand sterilization processes including autoclaving (121°C) and gamma irradiation without degradation or toxic byproduct formation.
In these demanding sectors, VT-SF must meet stringent safety standards such as SAE AMS 3320 for aerospace and ASTM D1418 for automotive seals . The fluid’s thermal stability (withstanding -60°C to +300°C continuously) ensures no toxic emissions even under extreme operational conditions, making it ideal for fuel system seals and engine components.
For electronics encapsulation and consumer products, high-purity VT-SF with low volatile content (<0.3%) minimizes outgassing risks . Biyuan’s specialized formulations achieve ±0.5% viscosity consistency, exceeding standard tolerance requirements to ensure predictable performance and enhanced safety in sensitive applications .
While VT-SF itself demonstrates low toxicity, proper handling remains essential:
Standard protocols for exposure include:
The toxicity profile of VT-SF significantly depends on manufacturing quality. Industrial-grade products may contain impurities or higher volatile content, while premium suppliers like Biyuan implement closed-loop production systems and rigorous purity controls to minimize potential contaminants .
Advanced manufacturers utilize headspace gas chromatography to precisely measure vinyl content and impurities, ensuring batch-to-batch consistency and reduced toxicity risks . This analytical precision separates premium VT-SF suitable for sensitive applications from standard industrial grades.
Modern Vinyl Terminated Silicone Fluid production increasingly addresses environmental concerns. Biyuan’s REACH-compliant formulations incorporate sustainable manufacturing practices aligned with EU Green Deal objectives, reducing environmental impact while maintaining performance . Properly formulated VT-SF demonstrates low ecological toxicity and supports circular economy principles through recyclable silicone systems.
Vinyl Terminated Silicone Fluid presents a low toxicity risk when handled according to manufacturer specifications and industry standards. Its well-characterized safety profile makes it suitable for diverse applications from medical devices to aerospace components. The key to safety lies in selecting premium-quality VT-SF from certified manufacturers like Biyuan, who adhere to international standards and provide comprehensive safety documentation.
By understanding the specific toxicity characteristics and implementing appropriate handling protocols, manufacturers can safely leverage the unique properties of Vinyl Terminated Silicone Fluid across industrial applications while ensuring workplace safety and regulatory compliance.
