Product Description
Description
High-Tech silicone rubber, also called highly transparent silicone rubber, refers to silicone with very high transparency (higher than glass).
Features
This type of silicone not only has the advantages of silicone rubber's high temperature and aging resistance, but also has the advantages of easy processing and high transparency.
Application
1. Silicone-robot dummies silicone
2. Aerospace aviation Silicone
3. Car field silicone
4. Marine vessel silicone
5. Military silicone rubber
Parameters
G series of addition molding translucent mold silicone rubber parameters (25℃)

Attention
1. The rubber material should be sealed and stored, and the mixed rubber material should be used up within the specified time to avoid waste
2. Do not let the rubber material and contain nitrogen (N), sulfur (S), phosphorus (P), tin (Sn), lead (Pb), mercury (Hg). Contact with alcohols, water, etc., such as organotin compounds and silicone rubber containing organic tin. Sulfur, sulfide, sulfur-containing rubber, amine compounds, and ammonia-containing materials. Also, do not contact containers or molds that contain condensation rubber. Otherwise, the addition molding liquid silicone will be sticky, incompletely cured or even not cured.
