The EPDM Rubber Extrusion Weatherstrip is a high-performance sealing solution specifically engineered for flat cabinet doors and industrial enclosures. Utilizing premium Ethylene Propylene Diene Monomer (EPDM) rubber, this seal strip provides an airtight and watertight barrier, effectively preventing the ingress of dust, moisture, and external contaminants while ensuring superior thermal insulation for sensitive electrical equipment and cabinetry.
Designed for versatility and durability, our rubber extrusion profiles are available in multiple materials including TPE, PVC, CR, NBR, and Silicone to meet specific environmental demands. Whether applied in automotive glazing, architectural curtain walls, or industrial machinery, these seals offer exceptional resistance to ozone, UV radiation, and extreme weather conditions, ensuring long-term structural integrity and operational efficiency.

Frequently Asked Questions
EPDM is generally superior for outdoor weatherproofing and ozone resistance, making it ideal for automotive and building exteriors. Silicone offers higher temperature resistance and is often preferred for food-grade or medical applications.
Yes, we provide professional sample customization. You can send us your physical sample or technical drawings, and we will develop the corresponding molds and fixtures for precision production.
While standard stock items can be delivered within 10 days, custom orders typically take between 30 to 60 days depending on the complexity of the mold and the total quantity ordered.
For electrical cabinets, EPDM or Flame Retardant sealing strips are recommended due to their excellent insulating properties and ability to block dust and moisture from sensitive components.
We use standard exported packing: each roll is usually 50 meters, wrapped in firm plastic bags and placed in professional cartons (approx. 505030 cm) to prevent deformation during transit.
We support free sample provision if the part is in stock. However, customers are generally responsible for the sample cost and courier shipping charges.
