Car seal strip is one of its important components, widely used in car doors, Windows, bodies, seats, sunroofs, engine case trunk and other parts, with waterproof, sealing, sound insulation, dust, frost prevention, shock absorption, warm and energy saving. 

    Automotive seals must have strong tensile strength, good elasticity, temperature resistance and aging resistance, so rubber seals have higher requirements for sliding seals. Next, introduce you to the detection of automobile seal strip. There are many ways to classify automotive seal products, usually according to the title of the device (parts), data varieties, composite data quantity, working characteristics and other factors to classify:  

    (1) according to the composite component classification: dense adhesive (single hardness is dense adhesive, different hardness is composite adhesive); Sponge rubber and dense rubber double compound; Sponge glue, dense glue and skeleton composite; Quadruple compound; Multi-compound, etc. 

   (2) According to the assembled parts of the car classification: door frame; Luggage strip; Engine cover strip; Guide groove; Inner and outer strips (inner and outer cut water); Head wind window and others. 

    Automobile doors and Windows rubber seals can be divided into solid core products (round, square, flat section shape), hollow products and metal EPDM rubber composite products according to the section shape. Among them, metal EPDM rubber composite seals account for more than 60%. There are three kinds of EPDM rubber materials for automobile sealing strips: dense rubber, sponge rubber and hard EPDM rubber. The sealant of the sealing strip uses aging resistance, low temperature resistance, water resistance, chemical corrosion resistance, especially the ozone aging resistance of EPDM rubber. EPDM can be combined with steel tape, steel wire braided tape, TPE, flannelette, flocking, PU coating, silicone coating, etc., to ensure that the car indoor and external and its own waterproof, dustproof,
