Solid EPDM rubber sealing strip
Stable hardness
Wear-resistant
water proof
These solid EPDM rubber sealing strips are manufactured using high-quality EPDM material via a continuous extrusion process, resulting in a dense, high-strength structure with excellent sealing and weather-resistant properties. Featuring stable hardness and resistance to wear and tearing, they effectively provide sealing, cushioning, dustproofing, waterproofing, and protection. They are widely used in applications such as architectural doors and windows, automotive door frames, construction machinery, equipment cabinet doors, and sheet metal joints. Customization of cross-sectional dimensions, hardness, color, and length is available based on customer drawings or samples.
Key Advantages:

EPDM adhesive strips
As the "King of Weather Resistance," EPDM rubber strips are renowned for their superior resistance to ozone, ultraviolet radiation, and heat oxidation. They maintain excellent elasticity and compression recovery over a wide temperature range of -40℃ to 120℃. Widely used in fields requiring extremely high long-term outdoor durability, such as automotive door and window seals and building curtain wall seals, they are the preferred material for withstanding wind and sun exposure, with a service life of up to decades.

Colored and black compound rubber
As the "cornerstone of rubber product performance," compounded rubber is a key intermediate material formed by homogenizing raw rubber with various compounding agents through precise formulation and efficient mixing processes. It possesses highly customizable physicochemical properties. It provides a ready-to-use semi-finished product for subsequent molding processes such as calendering, extrusion, and compression molding, and is widely used in almost all rubber product fields, including automotive, construction, electronics, and medical industries. It is the core foundation that determines the quality and reliability of the final product.
