Is the difference between rubber strip
s and silicone? Four composite sealing strip
s-Shanghai Shenya Sealing Parts Co., Ltd. is the first in China to develop and produce composite sealing strips composed of 4 kinds of rubber materials, which are wrapped on the surface of foam rubber (bubble tube). Covered with a thin protective layer of glue to further increase the service life of the seals. The car seals are classified according to the surface treatment state. The surface of the seals can be divided into flocking seals after additional treatment; surface coating seals ; There are special functional classifications of fabric-applied sealing strips for automobile sealing strips. Some sealing strips have electronic intelligence functions, such as anti-pinch sealing strips. Automobile product rubber formula and its preparation method and process Background technology: At present, the low temperature performance of rubber products used in automobiles on the market is generally around -25°C, but the rubber parts on automobiles cannot withstand cold air in a harsh climate. The airflow caused the product life to be greatly reduced. The performance of rubber products used in automobiles directly affects personal safety. For example, the recall of some of the cars sold by Toyota in the past few years caused serious reputational consequences. Therefore, all automobile manufacturers need a long-term stable performance. Adequately safe rubber products. The difference between rubber strip and silica gel plays a key role in various electrical cabinets. The main performance of EPDM products: the product is non-toxic, environmentally friendly, resistant to aging and high temperature, stable performance, and can be used in summer and winter To maintain good performance, considering the process performance of commonly used rubber materials, sometimes it is necessary to use combined rubber, such as natural rubber (NR) and CR and styrene butadiene rubber (SBR), or polyethylene (PE), EPDM and NR Rubber and plastic combined type to improve ozone resistance. , Elastomer TPE water floating sealing strip is applied to door and window sealing strip, mainly divided into: plastic steel door and window sealing strip, aluminum alloy door and window sealing strip, wooden door sealing strip, cold storage door sealing strip, grain storage door sealing strip, flame retardant door and window sealing strip , Glass sealing strips, automatic revolving door sealing strips, building door sealing strips, curtain wall sealing strips, etc., the so-called sealing strips with pores inside, this product is formed at one time through the microwave vulcanization process during production. Therefore, the surface is not only very smooth, but also has good aesthetics. It will not leave any joint marks during production. At the same time, the elasticity and resistance to compression deformation are also very strong. Let us take a detailed look at the hair The characteristics of the bubble sealing strip. The surface of the plastic steel door and window sealing strip is smooth and clean. It not only has excellent sealing and waterproof performance, but also plays a role of beautiful decoration. In terms of material selection, manufacturers with higher requirements generally choose EPDM rubber or thermoplastic EPDM rubber, according to the location And use classification (1) window glass sealing strip; (2) door sealing strip; (3) decorative strip, molding strip; (4) other sealing strips (trunk lid sealing strip, engine hood sealing strip, water tank sealing strip, Emergency door sealing strip, etc.). Technical realization factors: The technical problem to be solved by the present invention is to provide a rubber formula for automobile products and a preparation method thereof, which has good low-temperature performance, can withstand the attack of cold air in a local environment with relatively bad weather, and guarantees good performance. Ensure personal safety. Technical realization factors: The technical problem to be solved by the present invention is to provide a rubber formula for automobile products and a preparation method thereof, which has good low-temperature performance, can withstand the attack of cold air in a local environment with relatively bad weather, and guarantees good performance. Ensure personal safety. Is the difference between rubber strips and silica gel? For this reason, the GB12002-89 'Sealing Strips for Plastic Doors and Windows' was formulated very early to standardize the production and inspection of sealing strips. However, currently in the building materials market, rubber and plastic sealing strips for doors and windows The quality and price are very confusing. Four composite sealing strips-our company took the lead in developing and producing composite sealing strips composed of 4 kinds of rubber materials in China, and coated with a layer of foam rubber (bubble tube). The thin protective layer glue further improves the service life of the seal. Excellent weather resistance and aging resistance, ozone resistance, chemical corrosion resistance, flexible foam sealing strip, excellent cold and heat resistance (-50℃~+170℃), super elasticity, 200% stretch, good price Lian door and window sealing strip door and window sealing strip classification Plastic steel door and window sealing strip, aluminum alloy door and window sealing strip, wooden door sealing strip, cold storage door sealing strip, grain storage door sealing strip, flame retardant door and window sealing strip, glass sealing strip, automatic revolving door sealing strip, Building door sealing strips, curtain wall sealing strips, etc. Uses are mainly used in the door frame, side windows, front and rear windshield, engine cover and trunk cover, which play the role of waterproof, dustproof, sound insulation, temperature insulation, shock absorption, and decoration. The unique formula design makes three Ethylene propylene rubber sealing strip has excellent anti-aging, high and low temperature resistance and chemical resistance performance, has good elasticity and resistance to compression deformation, and will not crack or deform after long-term use. It is between -50 degrees and 120 degrees. It can maintain its original high sealing performance. Technical features: 1. An automobile product rubber, characterized in that the automobile product rubber is composed of EPDM, carbon black, softening oil, processing aids, and accelerators.
