IOTA 234 Diphenyltetrasiloxane is phenyl‑hydrogen‑containing siloxane cross‑linker. Its molecular structure contains phenyl groups and active Si‑H bonds to participate in hydrosilylation cross‑linking and build cross‑linked networks for phenyl‑silicone products. It is miscible with methyl silicone oil, liquid silicone rubber, phenyl silicone rubber and phenyl silicone resin. As cross‑linking component, it is applied in synthesis of addition‑cure silicone rubber, phenyl silicone rubber and phenyl silicone resin to deliver characteristic properties of phenyl‑silicone to cured articles. This high‑purity clear liquid features stable physicochemical performance. Available in 15 kg / 200 kg coated iron drums and stored in cool ventilated warehouse. It acts as key raw material for special‑grade phenyl silicone rubber and phenyl silicone resin formulations.
