Automotive door seal strips are indispensable components in vehicle manufacturing and maintenance, mounted along door frames, sashes, and contact edges. Their core function is to seal gaps between doors and the car body, blocking air leakage, water infiltration, dust, and external noise. Constructed from elastic, wear-resistant materials like EPDM or thermoplastic elastomer (TPE) for durability, they enhance cabin thermal insulation, improve air conditioning efficiency, and reduce driving noise. Applied in passenger cars, commercial vehicles, and trucks, they are critical for elevating ride comfort and protecting vehicle interiors.
