Hydride Terminated Polydimethylsiloxane CAS 70900-21-9

Introduction

This product has the characteristics of easy processing of polymers due to the Si-C bond contained in its molecular structure. Its main chain is composed of Si-O-Si bonds, which makes it have a structure similar to that of inorganic polymers, with high bond energy and good thermal stability. Therefore, it has the dual advantages of organic and inorganic materials, such as good thermal stability, low glass transition temperature, high air permeability, excellent dielectric properties, good biocompatibility and special surface properties.

Product Specifications

Application 

1. Used as a heat stabilizer for polyvinyl chloride, a curing agent for silicone rubber, a catalyst for polyurethane foam, etc. 
2. Used as a plastic stabilizer and a rubber curing agent 
3. It can be used as a heat stabilizer for polyvinyl chloride. It is the earliest type used in organotin stabilizers. It has excellent lubricity, weather resistance and transparency. It has good compatibility with plasticizers, does not spray frost, has no sulfide pollution, and has no adverse effects on heat sealing and printing properties. Because it is a liquid at room temperature, its dispersibility in plastics is better than that of solid stabilizers. This product is mainly used for soft transparent products or semi-soft products, and the general dosage is 1-2%. It has a synergistic effect when used in combination with metals or epoxy compounds such as cadmium stearate and barium stearate. In hard products, this product can be used as a lubricant and used in combination with maleic acid organotin or thiol organotin to improve the fluidity of resin materials.
