Fluorosilicone HTV (FVMQ) Silicone Rubber
Product Overview
Silico® FVMQ HTV Silicone Rubber is a high-performance, peroxide-cured elastomer that combines the excellent temperature stability of silicone with outstanding resistance to fuels, oils, solvents, and chemicals. Designed for extreme environments, it is widely used in aerospace, automotive, and industrial sealing systems where conventional silicone fails.
