IOTA 233 is T‑structured hydrogen‑terminated phenyl polysiloxane. Active Si‑H groups take part in hydrosilylation reaction to build cross‑linked networks for phenyl‑silicone products.
Wide adjustable ranges of molecular weight, viscosity and hydrogen‑content ensure good miscibility with various silicone matrices. As cross‑linking component for addition‑cure silicone rubber, phenyl silicone rubber and phenyl silicone resin, it endows end‑products with characteristic performance of phenyl‑silicone.
This chemically‑stable colorless viscous liquid is supplied in 15 kg / 200 kg coated iron drums and kept under cool‑ventilated storage. It serves as essential functional cross‑linking raw material for high‑temperature‑resistant phenyl silicone rubber and phenyl silicone resin.
