Product Description

Product Description

Product Introduction:
1. EPDM Sponge Foam Sealing Strip
EPDM sponge foam sealing strips are made from ethylene propylene diene monomer (EPDM) rubber, processed through a foaming technique to create a lightweight, flexible, and compressible material. The sponge-like structure provides excellent sealing performance, thermal insulation, and vibration damping. Ideal for irregular surfaces, it ensures airtight and watertight seals in dynamic or static applications.  
2. EPDM Solid Sealing Strip
EPDM solid sealing strips are dense, non-porous rubber profiles known for exceptional durability, UV resistance, and weatherproofing. Their robust structure offers long-term resistance to extreme temperatures, ozone, and chemicals, making them suitable for heavy-duty industrial and construction applications.
