Automotive Applications
Our precision extruded rubber solutions protect and enhance vehicle systems across entire platforms,from conventional powertrains to next-generation electric vehicles.
Door Seal Systems
Automotive door weatherstrips are mounted to the door panel using adhesive backing or plastic fasteners (retaining clips), forming the primary seal between the door and vehicle body to effectively block ingress of external contaminants including water, dust, wind noise and airborne particles.
Luggage Weatherstrips
Tailgate weather seals install along body panel edges to form a secure barrier against moisture, air and contaminants entering the cargo area. Our proprietary EPDM formulations deliver superior permanent set resistance, mechanical strength, and outstanding resistance to weathering, UV, chemicals and extreme temperatures.
Sunroof sealing strip
Sunroof seals strips are installed along sunroof openings to prevent water, noise and air leakage, our EPDM rubber compounds offer excellent UV resistance, compression set properties, water resistance and temperature stability from -40°C to 120°C.
Door Glass Runs
Door Glass Runs can be extruded in different geometries and sizes to meet automotive sealing needs. The main material choice is EPDM compounds, and the products include: Door Glass Runs (flocking lined or surface coated models), Fiber Impregnated Rubber Runs, Flocked Integrated Glass Runs and other non-reinforced all-rubber runs with optional flocked/coated inner surfaces.
