Optimizing Mechanical Properties with methyl hydrogen silicone fluid
In silicone rubber production, methyl hydrogen silicone fluid serves as a key crosslinking agent due to its active Si-H groups, which react with vinyl-functionalized polysiloxanes via hydrosilylation. This reaction, catalyzed by platinum complexes, forms a thermally stable, three-dimensional network.
Studies show that optimized MHSF concentrations (0.5–2.0 wt%) improve tensile strength by 25% and elongation at break by 30% in high-consistency rubber (HCR). Furthermore, its low volatility ensures minimal weight loss during curing, making it essential for high-performance seals, gaskets, and automotive components exposed to extreme temperatures.
