Product Overview

30cst Methyl Hydrogen Silicone Oil (CAS 63148-57-2) is a high hydrogen content polymethylhydrosiloxane with 1.55% active hydrogen. It is specially developed as a high-efficiency crosslinker for LSR liquid silicone rubber. Featuring even molecular weight distribution and consistent reactive activity, this PMHS fluid is the ideal cross-linking raw material for addition cure silicone formulations.

Key Features

1.55% high active hydrogen content, stable crosslinking reactivity
Low volatility, excellent compatibility with vinyl silicone polymer
Moderate viscosity of 30cst, convenient feeding and uniform mixing
No by-products generated during curing, keeping LSR products transparent
Improve tensile strength, elasticity and thermal stability of finished silicone parts

Main Applications

Crosslinking agent for LSR liquid silicone rubber
Addition curing system for food-grade & industrial liquid silicone
Raw material for silicone coating, silicone encapsulant
Modifier for various vinyl-containing silicone materials

Usage Guidance

Mix uniformly with vinyl silicone base rubber under platinum catalyst environment. The dosage should be adjusted according to target hardness and curing requirements. Avoid contact with tin catalysts, amines and heavy metal substances which may cause premature gelation.

Storage & Package

Seal and store in a cool, dry and ventilated warehouse, keep away from direct sunlight and high temperature. Standard packaging: 25kg plastic drum, 200kg iron drum. Shelf life: 12 months under proper storage conditions.
