Addition Cure Molding Silicone Rubber

Name:Addition Cure Molding Silicone Rubber
Number: HY-988
Count: 438
Distribution time: 2010-06-17
Usage:For making precision molds, silicon insoles, food grade molds, such as chocolate, cake moulds, baby nipples, mobile shell and models, superior manual mold design, etc.

Description:
HY-988 is a kind of addition cure high temperature resistance organic molding silicone in liquid form. It's a two-component material with mixing ratio of 10:1 and with moderate viscosity and can be poured and brushed. The mold made out of the part A liquid silicone and part B the platinum curing agent, which with high temperature up to 250-300℃, has dimension stability, low linear shrinkage.

Features:
Silicone rubber will not release low molecule under the condition of crosslinking,so the volume will not vary,linear shrinkage will less than 0.1%;it does not subject to the thickness of the products, and can be cured deeply;it with high tensile and tear strength and anti-yellowy under high temperature of 200℃.

Applications:
It's applicable to make precision molds, silicon insoles, food grade molds, such as chocolate, cake moulds, baby nipples, mobile shell and models, superior manual mold design, etc.
