Injection molding of liquid silicone rubber LSR Manufacture China two-part platinum-cured elastomer
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
Ruihe RH6250 SERIES Liquid Silicone Rubber (F-LSR) is specifically designed for liquid injection molding.
The product is supplied as a two component, soft fluorosilicone paste. It heat cures to a 60 durometer material.
The cured rubber product is resistant to a wide variety of solvents and chemicals over a wide temperature range
of -63 to +175°C (-82° to +347°F) under immersion conditions, and up to +225°C (+437°F) in dry heat.
