Custom-profile EPDM rubber sealing strips
damping
Noise reduction
Temperature stability
Automotive EPDM profiled rubber weatherstrips are manufactured using high-quality EPDM (Ethylene Propylene Diene Monomer) material via a precision extrusion process, featuring diverse cross-sectional profiles designed to suit specific vehicle models and installation locations. These products offer excellent elasticity, weather resistance, temperature stability (withstanding both high and low temperatures), and aging resistance; they effectively fill gaps between vehicle body components to provide sealing, vibration damping, noise reduction, and protection. Widely used for vehicle doors, windows, bodywork, trunks, engine compartments, and other areas requiring sealing and cushioning, these strips can also be custom-developed based on customer drawings, samples, or technical specifications.
Key Advantages:

High-quality EPDM material: Resistant to ozone, UV radiation, and aging; suitable for long-term outdoor use.
Excellent temperature resistance: Maintains good elasticity and sealing performance in both extreme cold and high-heat conditions.
Multi-lip sealing design: Increases the sealing contact area, effectively blocking the ingress of rain, dust, and air.
High resilience: Resists permanent deformation after prolonged compression, ensuring a consistent seal.
Vibration and noise reduction: Minimizes vibration and wind noise at vehicle doors, windows, and body joints.
Secure and reliable installation: Supports slot-in, clip-on, and embedded installation methods.
Flexible profile customization: Custom profiles can be developed based on CAD drawings or samples.
Stable dimensional accuracy: Precision extrusion ensures cross-sectional consistency, meeting mass production requirements.

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.
