IOTA 231 is a hydrogen-terminated linear phenyl silicone oil with active Si-H bonds at both ends of the molecular chain, with a molecular weight range of 333–1000. As a crosslinker for addition-cure silicone rubber, phenyl silicone rubber, and phenyl silicone resin, it exhibits good compatibility with various silicone materials, providing controllable crosslinking density and excellent curing performance.
Hydrogen-Terminated Structure: Active Si-H groups at both ends, well-defined reactive sites, high crosslinking efficiency.
Good Compatibility: Highly compatible with methyl silicone oil, liquid silicone rubber, phenyl silicone rubber, and phenyl silicone resin, ensuring uniform dispersion.
Controllable Crosslinking Density: Adjusts the degree of crosslinking and mechanical properties of vulcanizates via dosage variation.
Enhanced Temperature Resistance: The introduction of phenyl groups improves thermal stability and aging resistance of silicone rubber.
