Process characteristics of door and window seals
Jan 12, 2019

  The use of door and window seals is more and more extensive. Plastic steel door and window seals are widely used in the new generation of doors and windows in recent years. They have better anti-corrosion, weather resistance, noise reduction and heat insulation effect than ordinary door and window seals. The surface of plastic steel door and window seals is smooth, which not only has excellent sealing and waterproof performance, but also plays a role of beautiful decoration. In terms of material selection, EPDM rubber or thermoplastic EPDM rubber are generally used by manufacturers with higher requirements. Main properties of EPDM products: non-toxic, environmental protection, aging resistance, high temperature resistance, stable performance, good performance in summer and winter. 1. Steel skeleton three-compound, not easy to deform and shrink, solid assembly, good sealing 2, door, window, curtain wall sealing strip, the product has good elasticity, migration resistance, can effectively block noise, dust, wind and rain.

  Type D sealing strip can be divided into large D sealing strip, small D sealing strip, P sealing strip and E sealing strip. Automotive sound insulation and anti-collision strip is divided into three types: 3M back glue small D seal strip, 3M back glue large D seal strip and 3M back glue large P seal strip. However, with the development of automotive industry in recent years, a kind of domestic Wande double-sided adhesive occupies more and more market share. It overcomes the shortcomings of 3M adhesive construction which is not cold-resistant, simple to construct, sticky and durable, and overcomes the influence of temperature on the life of sealing strip before! Sealing strip market is mainly made of EPDM rubber, rubber and plastics. According to its use, it can be divided into automobile sealing strip, mechanical sealing strip, door and window sealing strip and so on. The sealing strips of doors and windows are classified into plastic steel sealing strips, aluminum alloy sealing strips, wood sealing strips, cold storage door sealing strips, grain depot door sealing strips, flame retardant door and window sealing strips, glass sealing strips, automatic rotating door sealing strips, building door sealing strips, curtain wall sealing strips, etc.

  Classified according to position and use (1) window glass seal strip; (2) door seal strip; (3) decorative strip and inlay strip; (4) other seal strips (suitcase cover seal strip, engine hood seal strip, water tank seal strip, emergency door seal strip, etc.). According to the classification of materials, there are three kinds of rubber materials for automobile seals: solid rubber, sponge rubber and hard rubber. The hardness of hard rubber can reach Shao's A95. Sealing strips are mostly made of EPDM, which is resistant to aging, low temperature, moisture and chemical corrosion, especially ozone aging. EPDM can be combined with steel strip, steel wire braided belt, TPE, flannel, flocking, PU coating and silicone coating to ensure the waterproof, dust-proof, sound-proof, heat-proof, vibration-reducing, wear-proof and decorative functions of the car interior and the outside world as well as its own. Generally, EPDM seals can be used stably for more than ten years. Chloroprene rubber (CR) with good ozone resistance and aging resistance can also be selected.
