This product is a high-performance composite component manufactured using fluorosilicone (FVMQ) overmolding on PA+GF (Glass Fiber Reinforced Nylon).

It combines the high mechanical strength and dimensional stability of PA+GF with the excellent chemical resistance and elasticity of fluorosilicone rubber, making it suitable for demanding industrial, automotive, and fluid system applications.

The overmolding process forms a durable interface between the rigid structural substrate and the flexible sealing layer, enabling both load-bearing capability and reliable sealing performance in harsh environments.
