IOTA 232 Tetramethyldiphenyltrisiloxane is a phenyl‑hydrogen terminated cross‑linking monomer. With built‑in phenyl groups, it takes part in hydrosilylation cross‑linking for addition‑cure systems. Cross‑linked phenyl silicone rubber and phenyl silicone resin obtain characteristic performance brought by phenyl segments. It mixes well with methyl silicone oil, liquid silicone rubber and other phenyl silicone polymers for synthesis and processing of phenyl silicone rubber and resin. This high‑purity clear liquid has boiling point 130‑131℃@2.5 mmHg and stable physicochemical properties. Available in 15 kg / 200 kg coated iron drums and keep in cool ventilated warehouse. It serves as essential cross‑linking raw material for high‑end phenyl‑silicone formulations.
