High Viscosity 107 Silicone Rubber is hydroxyl‑terminated polydimethylsiloxane, CAS 70131‑67‑8. This high viscosity base polymer is optimized for extrusion grade silicone sealant. It has outstanding compatibility with reinforcing fillers and thixotropic agents. After condensation curing, finished sealant shows good mechanical strength, elastic recovery and weather resistance. It adapts to automatic extrusion production line for mass manufacturing of one‑component and two‑component silicone seala

Product Detail

Product Overview

High Viscosity 107 Silicone Rubber is hydroxyl‑terminated polydimethylsiloxane base polymer, CAS 70131‑67‑8. This condensation‑cure PDMS is developed for extrusion grade sealant production. Viscosity and hydroxyl value are strictly controlled batch‑by‑batch. When compounded with fillers, thixotropic additives and cross‑linking system, it delivers stable rheological property to meet high‑speed extrusion requirement of sealant production lines. Stable raw‑material quality supports continuous large‑volume sealant manufacturing.

Key Features

High viscosity 107 silicone polymer customized for extrusion grade sealant
Stable hydroxyl terminal groups for consistent condensation cross‑linking
Excellent wetting and dispersion effect for high‑loading mineral fillers
Good rheology adaptability, cooperates well with thixotropic additives
Guarantees smooth extrusion without sagging during sealant production
Cured sealant possesses high elasticity, cohesive strength and weather resistance
Fits one‑part and two‑part sealant extrusion process
Low volatile impurities, reliable batch‑to‑batch repeatability
Suitable for automatic continuous sealant production line

Main Applications

Base polymer for extrusion grade construction silicone sealant
Raw material for one‑component and two‑component condensation‑cure sealant
Industrial extrusion silicone sealant and adhesive compound
High‑speed automatic production of neutral and acetic silicone sealant
Custom extrusion‑process silicone sealant formulations

Processing Suggestions

Perform feeding, kneading and dispersion under strictly moisture‑free workshop environment. Compound with reinforcing fillers, thixotropic agent, cross‑linking agent and catalyst according to sealant formula. Adjust filler and additive dosage to get ideal extrusion performance and anti‑sagging property. Prevent moisture intrusion in full production flow to avoid premature curing and product defects.

Storage & Packing

Packed in sealed 200kg iron drum. Store in cool, dry and ventilated warehouse. Keep drum tightly sealed. Keep away from humidity, high temperature and direct sunlight. Reseal drum immediately after partial material discharge. Proper storage retains polymer reactivity and ensures valid shelf‑life.
