Good qulity liquid silicone injection molding process is highly automated with short cycle times

A Liquid Silicone Rubber material is a two-part platinum-cured elastomer that can be injected into a mold cavity to manufacture a part.

LSR is very versatile in the elastomer industry and is seen across a whole spectrum of parts from consumer products to medical devices and everything in between.

Most silicone rubber varieties share in common naturally-occurring qualities of high electrical insulation, resistance to extreme temperatures, chemical inertness and resilience in harsh environments.

Product description

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.

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.
