What are the different processing methods for silicone rubber?
Liquid silicone rubber is a high-purity, two-component platinum-cured silicone reinforced with specially treated silica. It is specially formulated for producing technical parts, where strength, resistance and high quality are a must. LSRs are less viscous than HCRs and therefore pumpable materials, ideal for liquid injection molding.
