IOTA 2238 Pentamethylphenyl dihydrotrisiloxane contains phenyl groups and active Si‑H bonds in its molecular structure. It participates in hydrosilylation cross‑linking to build cross‑linked networks for phenyl‑silicone polymers.
It is well‑miscible with methyl silicone oil, liquid silicone rubber, phenyl silicone rubber and phenyl silicone resin. Used as cross‑linker for addition‑cure silicone rubber, phenyl silicone rubber and phenyl silicone resin, it endows cured products with characteristic properties of phenyl‑silicone materials.
This high‑purity clear liquid delivers stable physicochemical performance. Available in 25 kg / 200 kg internally coated iron drums. It is an indispensable functional raw material for manufacturing high‑end phenyl silicone rubber and phenyl silicone resin.
