Product Detail

Product Overview

Industrial Grade 107 Silicone Raw Material is hydroxyl‑terminated polydimethylsiloxane base polymer, CAS 70131‑67‑8. Featuring 99% high polymer purity and controlled minor impurities, this condensation‑cure PDMS is manufactured for general industrial silicone production. Key indicators including viscosity and hydroxyl value are strictly monitored batch by batch. It meets formulation requirements of sealant factories, silicone compound plants and RTV rubber manufacturers for stable industrial raw material supply.

Key Features

99% high polymer purity, low volatile and impurity content
Precisely controlled viscosity and stable hydroxyl terminal groups
Great compatibility with mineral fillers and different silane cross‑linkers
Predictable condensation cross‑linking reaction for stable finished‑product quality
Excellent batch‑to‑batch consistency for continuous industrial production
Wide formula adaptability for sealants, adhesives and RTV silicone rubber
Strict quality inspection for each production batch

Main Applications

Base polymer for acetic and neutral silicone sealant production
Raw material for silicone adhesive and bonding compound
Condensation‑cure RTV‑2 mold‑making silicone rubber formulation
Industrial silicone compound for construction, electronic and sanitary fields
Custom condensation‑cure silicone products requiring high‑purity base resin

Processing Suggestions

Carry out pumping, feeding and kneading operations under moisture‑free working environment. Prevent moisture intrusion during material handling. Combine with cross‑linking agents, catalysts and functional fillers according to target product formula. Water contamination will cause incomplete curing and surface tacky defects.

Storage & Packing

Packed in sealed 200kg iron drum. Store in cool, dry and ventilated warehouse. Keep drums tightly sealed. Avoid moisture exposure, high temperature and direct sunlight. Reseal drum immediately after partial material discharge. Proper storage maintains polymer reactivity and ensures full shelf‑life.
