Methyl Hydrogen Silicone Fluid
Everything you need to know about our products and company
Methyl hydrogen siloxane serves as a multifunctional additive that significantly improves processing characteristics and final properties in silicone rubber applications. This specialized silicone fluid features reactive Si-H groups that enable efficient cross-linking through hydrosilylation reactions with vinyl-functionalized silicone rubbers.
In high-temperature vulcanization (HTV) systems, it acts as an effective cross-linking agent that increases curing speed by over 50% while providing precise control over cross-linking density. This results in enhanced tear strength (40% improvement) and extended service temperature resistance up to 200°C, making it ideal for demanding automotive and industrial applications.
For liquid silicone rubber (LSR) formulations, Methyl hydrogen siloxane effectively eliminates bubble formation during curing, reducing porosity by 90% while improving flow characteristics and mold release properties. It significantly enhances adhesion to various substrates including metals and plastics, achieving peel strength values of 4.5 kN/m.
Certified to FDA and USP Class VI standards, hydrogen-containing silicone oil finds widespread use in medical and food-grade silicone products. With precisely controllable hydrogen content (0.01%-1.6%) and molecular weight distribution, it provides tailored solutions for various performance requirements, establishing itself as an essential material for developing high-performance silicone rubber products.
