Features Of 1-000-50 High-Hydrogen Silicone Oil

  1. High active hydrogen content (≥4.5 wt%) enabling efficient hydrosilylation reactions.

  2. Low viscosity (30–50 cSt at 25°C) for excellent processability and uniform dispersion.

  3. Excellent thermal stability up to 200°C, supporting high-temperature curing processes.

  4. High purity with minimal cyclic siloxane residues (<0.5%), ensuring consistent crosslinking performance.

  5. Compatible with platinum-based catalysts and common functional silicones (e.g., vinyl-terminated PDMS).

Typical Applications Of 1-000-50 High-Hydrogen Silicone Oil

  1. Hydrosilylation-curable liquid silicone rubber (LSR) formulations.

  2. Crosslinking agent in heat-cured silicone gels for electronics encapsulation.

  3. Functional additive in pressure-sensitive adhesive (PSA) modifiers for enhanced cohesion.

  4. Surface treatment agent for silica fillers in high-performance silicone elastomers.

  5. Key component in optical-grade silicone resins for LED lens encapsulation.
