107 Silicone Raw Material 80000 cst is hydroxyl‑terminated polydimethylsiloxane with CAS 70131‑67‑8. As high‑viscosity 107 base gum, it provides excellent elasticity and high elongation after cross‑linking. With stable viscosity and reliable batch consistency, it is widely used for formulating high‑performance neutral sealants, special RTV silicone rubber and customized silicone compounds.

Product Detail

Product Overview

107 Silicone Raw Material 80000 cst is OH‑terminated polydimethylsiloxane, well‑known as 107 silicone rubber base polymer, CAS 70131‑67‑8. This high‑viscosity grade is designed for demanding condensation‑cure silicone systems. Controlled hydroxyl end‑groups guarantee predictable cross‑linking reaction. Strict production control ensures stable viscosity and consistent performance across batches for industrial large‑scale formulation.

Key Features

High viscosity 80000 cst for high‑elasticity silicone end products
Reactive hydroxyl terminal groups for condensation cross‑linking
Good compatibility with diverse silane cross‑linkers and mineral fillers
Delivers high elongation and low‑modulus performance after curing
Low volatile impurities, stable storage performance
Reliable batch‑to‑batch uniformity for continuous production

Main Applications

High‑elongation neutral silicone sealant formulation
Special one‑component and two‑component RTV silicone rubber
High performance silicone adhesive raw material
Modified silicone compound manufacturing
Industrial sealing, potting and gap‑filling silicone products
Custom condensation‑cure silicone formulation

Processing Suggestions

All mixing, dispersion and grinding operations must be completed under moisture‑isolated conditions. Match with corresponding cross‑linking agents, catalysts and functional fillers. Adjust formula proportion according to target hardness, tensile strength and elongation requirements. Strictly prevent moisture contamination during the whole manufacturing process.

Storage & Packing

Store in cool, dry and ventilated warehouse, keep containers fully sealed. Avoid moisture intrusion, high temperature and direct sunlight. Standard iron drum packaging. Reseal drum tightly immediately after partial discharge. Observe recommended storage conditions to maintain full shelf‑life.
