Chemical Information

Main component:dual-end vinyl Polydimethylsiloxane

Cas No.：68083-19-2

Molecular Structure:CH₂=CH-(CH₃)SiO[Si(CH₃)₂O]_nSi(CH₃)CH=CH₂

The NV-SIVI280L Series is a high-purity linear polydimethylsiloxane with reactive vinyl terminals, specifically processed to minimize low-molecular-weight cyclic siloxanes. By leveraging advanced stripping technology, this series maintains a strictly controlled cyclic content (D3-D10 < 500ppm or < 100ppm), ensuring full compliance with the most rigorous global environmental and health regulations, such as EU REACH. It provides a reliable, high-purity base for formulations where regulatory safety and the reduction of siloxane migration are critical priorities.

Typical properties

Key Features & Benefits:

Regulatory Excellence: Strictly controlled low molecular weight cyclic siloxanes (D3-D10) to meet stringent global environmental standards, including EU REACH and silicones industry restrictions.

Low Outgassing: Minimizes fogging and siloxane migration, ensuring long-term stability in enclosed systems

High Purity Base: Refined through advanced thin-film evaporation to ensure consistency in high-performance formulations.

Linear Reactivity: Provides a precise and stable crosslinking network when cured with platinum catalysts and hydrogen-containing silicone oils

Applications:

Electronics & Semiconductors: Ideal base polymer for potting compounds and thermal interface materials (TIMs) where outgassing must be avoided.

High-End Silicone Rubbers: Used in the production of Liquid Silicone Rubber (LSR) for infant care, medical components, and food-contact items.

Specialty Coatings: Solvent-free release coatings and pressure-sensitive adhesives (PSA) requiring high environmental compliance.
