New Sealing Strip
A solid sealing strip is a compact, non-porous, foam-free sealing product typically made from base materials such as ethylene propylene diene monomer (EPDM), silicone, or PVC. It is produced through processes including extrusion and vulcanization. Some products also feature an embedded metal skeleton to enhance their shape-retaining capability.

Foam sponge seals (also known as foamed sponge seals) are porous, elastic sealing products manufactured by injecting a foaming agent into base materials such as rubber, silicone, and EPDM, followed by vulcanization and foaming processes. Their internal structure is honeycomb-like or highly porous, combining the characteristics of “soft elasticity + high compression recovery + lightweight.” Their primary functions include filling gaps, providing cushioning and shock absorption, and offering sound and thermal insulation. They are widely suitable for applications that require relatively low sealing pressure but also demand comfort.

Silicone sealing strips are elastic sealing products made from silicone rubber (silicone) as the core raw material through processes such as mixing, extrusion, and vulcanization. Thanks to the unique chemical stability and physical properties of silicone materials, these strips have become versatile, high-performance sealing components widely used across various industries, playing an irreplaceable role in demanding environments and precision applications.

Silicone, formally known as silicone rubber, is a high-molecular elastomer with a backbone primarily composed of silicon-oxygen bonds. It exhibits excellent resistance to both high and low temperatures, remaining stable over an extreme temperature range from -60°C to 250°C and resisting aging and deformation easily.
