PVC Seal

A PVC seal is a flexible, durable gasket made from polyvinyl chloride (PVC), designed to provide waterproof, dustproof, and weather-resistant sealing in construction, automotive, and industrial applications. It offers a cost-effective alternative to rubber seals while maintaining reliable performance in moderate conditions.
Key Features & Benefits
✔ Weather & UV Resistant – Withstands sunlight, rain, and temperatures from -20°C to 70°C (-4°F to 158°F).
✔ Chemical Resistance – Resists mild acids, alkalis, and oils (not suitable for strong solvents).
✔ Lightweight & Flexible – Easy to install in tight spaces without cracking.
✔ Flame Retardant – Meets UL94 HB/V0 standards (optional).
✔ Customizable – Available in strips, cords, or molded shapes.

Applications
Windows & Doors – Weatherstripping for homes/offices.
Electrical Enclosures – Seals control panels and junction boxes.
Automotive Trims – Edge protection for doors and hoods.
Installation Tips
Clean surfaces before applying adhesive-backed seals.
For hollow profiles, ensure even compression to avoid gaps.
Replace if discolored, brittle, or deformed.
