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.
Application
These grades are particularly suitable for the economical production of large series of injectionmoulded articles.
Parts made from RUI-HE RH6250-50 can be used for technical and pharmaceutical applications.
These articles are also suitable for use in conjunction with foodstuffs.
Processing
Mixing
Rui-he RH 6250 series Liquid Silicone Rubber is a two-component material supplied as parts A and B,
which should be combined in a 1:1 ratio. Meter mix equipment which pumps, meters, and mixes
the two components without the incorporation of air is strongly recommended for production.
Pot Life
After the A and B components are mixed, Liquid Silicone Rubber will remain usable for at least 48 hours at room temperature.
Storage
The 'Best use before end' date of each batch is shown on the product label.
Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable.
In this case however, the properties required for the intended use must be checked for quality assurance reasons.
