LR-120 Methylphenylsilicone Rubber Gum (120 Silicone Rubber)

M.W. 50~80 (×10000); M.W. 40~70 (×10000)

Gum silicone rubber serves as a versatile raw material for phenyl-mixed glue, offering low-temperature resistance, high-temperature endurance, and radiation protection. Building on this foundation, the fluorosilicone (FVMQ) silicone rubber gum offered by brands Silfluo introduces superior chemical stability for the most demanding applications. In its raw form, this gum silicone rubber has a clay-like consistency, requiring milling and catalysts to be vulcanized into a solid, elastic material—realizing the full application potential of gum silicone rubber.
