IOTA 234 Diphenyltetrasiloxane (CAS:66817‑59‑2) is colorless transparent liquid with GC purity ≥95%. Specific gravity:1.005, refractive index (20℃):1.4622, flash point＞110℃, boiling point 95‑96℃/0.25 mmHg. Stable batch‑to‑batch performance. As phenyl‑modified hydrogen‑containing cross‑linker, it exhibits excellent compatibility with methyl silicone oil, liquid silicone rubber, phenyl silicone rubber and phenyl silicone resin without phase separation, facilitating formula adjustment. It is used for cross‑linking of addition‑cure silicone rubber, phenyl silicone rubber and phenyl silicone resin. Packed in 15 kg and 200 kg coated iron drums. Store in cool and ventilated place. Suitable for industrial‑scale production of high‑end phenyl‑silicone materials.
