107 Silicone Rubber Base is hydroxyl‑terminated polydimethylsiloxane, CAS 70131‑67‑8. It is general‑purpose base polymer for RTV‑2 two‑component condensation cure mold‑making silicone. With controllable silanol groups, it can react with cross‑linker and organotin catalyst to form flexible silicone rubber. The finished mold features low linear shrinkage, good elasticity and excellent pattern replication capability, widely used for art craft reproduction, resin casting and various industrial mold

Product Detail

Product Overview

107 Silicone Rubber Base belongs to hydroxyl‑terminated polydimethylsiloxane series, CAS 70131‑67‑8. This is general‑purpose base polymer designed for RTV‑2 condensation cure mold‑making silicone. Hydroxyl content and viscosity are strictly controlled for each production batch. After compounding with reinforcing fillers, silane cross‑linking agent and organotin catalyst, it cross‑links into flexible elastic silicone rubber. Reliable batch consistency supports mass production of different kinds of casting molds.

Key Features

General‑purpose 107 base polymer for RTV‑2 two‑component condensation cure mold silicone
Stable hydroxyl terminal groups for predictable condensation curing reaction
Excellent wetting and dispersing performance for reinforcing silica fillers
Cured silicone rubber exhibits low linear shrinkage rate
High elasticity and good tear resistance for repeated demoulding
Outstanding fine‑detail reproduction for complex patterns and textures
Wide formula adaptability for soft and medium‑hard mold grades
Compatible with standard silane cross‑linkers and organotin catalysts
Low volatile content, stable batch‑to‑batch repeatability

Main Applications

RTV‑2 condensation cure mold‑making silicone compound
Art craft, sculpture and ornament reproduction molds
Resin, plaster, wax and low‑melting‑point material casting moulds
Custom flexible molds for small‑batch industrial duplication
Prototype tooling and decorative article mold production
Multiple general‑purpose mold silicone formulations

Processing Suggestions

Complete feeding, kneading and mixing operations under strictly moisture‑free environment. Add reinforcing fillers, silane cross‑linking agent and organotin catalyst according to target mold formula. Adjust filler loading to achieve required hardness, tear strength and shrinkage indicator. Keep moisture away during whole production procedure to avoid incomplete curing and surface tacky defects.

Storage & Packing

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