OH Terminated PDMS 10000 cst, also known as 107 silicone rubber, is hydroxyl‑terminated polydimethylsiloxane with CAS 70131‑67‑8. It features moderate viscosity, excellent cross‑linking reactivity and consistent batch stability. As general‑purpose base polymer, it is widely adopted in condensation‑cure RTV silicone formulations for sealants, adhesives and various silicone compound production.

Product Detail

Product Overview

OH Terminated PDMS 10000 cst is a hydroxyl‑terminated polydimethylsiloxane, commonly named 107 silicone rubber base polymer. With CAS number 70131‑67‑8, this general‑grade raw material serves as core base resin for condensation cure silicone systems. It delivers balanced viscosity and reliable hydroxyl content, ensuring stable curing performance in downstream formulation.

Key Features

Controlled 10000 cst viscosity for easy mixing and processing
Reactive hydroxyl end groups for condensation cross‑linking
Low impurity, good batch‑to‑batch consistency
Compatible with silane cross‑linkers and filler systems
Excellent weather resistance after curing
General‑purpose grade suitable for multiple industrial formulas

Main Applications

One‑component and two‑component RTV silicone rubber
Construction and industrial silicone sealants
Silicone adhesive raw material
Silicone compound and potting compound production
General condensation‑cure silicone formulation

Processing Suggestions

Mix with cross‑linking agent, catalyst and inorganic fillers under moisture‑free environment. Avoid long‑term exposure to humid air before usage. Adjust formula ratio according to target hardness and mechanical requirements of finished silicone products.

Storage & Packing

Seal tightly and store in cool, dry and ventilated warehouse. Keep away from moisture, high temperature and direct sunlight. Standard packing in iron drum. Keep container closed after partial use to prevent moisture ingress. Shelf life is guaranteed under proper storage conditions.
