Single-extruded sponge rubber strip
Flexibility
Flexibility
Flexibility
This product is manufactured using high-quality EPDM sponge rubber via a continuous single-extrusion process, featuring a composite structure that combines guide channels with protruding ribs. It offers excellent flexibility and stable resilience, ensuring a tight fit against vehicle windows, doors, sheet metal, and architectural structures to provide reliable sealing and cushioning. It is widely used in architectural doors and windows, automotive glass guide channels, door interior trim edges, vehicle body sheet metal seams, and various slot-mounted applications; dimensions, hardness, density, color, and length can be customized to meet specific customer requirements.
Key Advantages:

Dimensional stability: Single-extrusion process ensures a consistent cross-section, suitable for mass production.
Guide-channel design: Enables precise positioning during installation and ensures a secure fit.
High resilience: Effectively compensates for assembly tolerances and maintains long-term sealing performance.
Excellent sealing: Provides water, dust, and sound insulation, reducing wind noise and unwanted rattling.
Shock absorption and cushioning: Minimizes friction and impact between the glass, interior components, and the vehicle body.
Weather and aging resistance: Resistant to ozone and UV radiation, making it suitable for long-term outdoor use.
Easy installation: Flexible and pliable; compatible with clip-in or press-fit installation methods.

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.
