LSR is platinum-cured and natural transparent silicone which is more transparent than solid silicone. Liquid silicone rubber can mixed with pigmentation to produce colorful LSR molded products.
The silicone products we supply include liquid silicone rubber and room temperature vulcanizing silicones.
The products are transformed into silicone elastomers through the process of vulcanization.
Our silicone rubber products deliver excellent performance in the silicone engineering range of products
Product description
Silicone rubber molding is accomplished in five different ways:
1. cast molding,
2. injection molding,
3. compression molding,
4. transfer molding
5. dip molding
