Rubber sealing strips are designed to create airtight and watertight seals that prevent the ingress of air, water, dust, and other contaminants. The materials used in manufacturing these strips significantly influence their performance. High-quality rubber, often silicone or EPDM (ethylene propylene diene monomer), demonstrates excellent elasticity, resilience, and resistance to harsh environmental conditions. This makes it an ideal choice for sealing strips that must withstand extreme temperatures, UV exposure, and chemical corrosion.
