Silicone strip extruder information, and it also has good dustproof, sound insulation and decorative effects. It also protects the car body and effectively improves the comfort of the ride. The characteristics of the car seal are resistant to -40°C. In the low-temperature experiment, the sealing strip does not become hard and brittle, and still maintains softness and good adhesion of the strip, showing excellent cold resistance. The performance characteristics of the EPDM sealing strip: excellent comprehensive performance and outstanding resistance Ozone resistance, excellent weather resistance, good high temperature and low temperature resistance, outstanding chemical resistance, resistance to a variety of polar solutes, and low relative density. 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 auxiliary seal of the information compensation ring of the silicone strip extruder is a metal bellows called a bellows mechanical seal. 2. The composition of the mechanical seal: mainly includes the following four types of components, a. The main seals: moving ring and static ring, b , Auxiliary seal: sealing ring, c, compression: spring, push ring, d, three, and put the PVC sealing strip and silicone rubber sealing strip in the freezer compartment of the refrigerator at the same time. After a few hours, the PVC sealing strip will become The hand feels very stiff, easy to break, and the physical properties of the silicone rubber seal have no change. Doors and windows are the barriers to the quiet living environment. Doors and windows are also important and interesting bridges between people's internal world and the external world. The sealing performance of doors and windows is constantly enriched, and the opening is more and more catering to the needs of life. This significant change It implies the improvement of the quality of life. In fact, they all represent a trend of living quality. When doors and windows form concepts in the process of human civilization, doors and windows have also become another carrier of human civilization, and they can be used to satisfy the use of functions. Transformed into a desire for spiritual refuge and ideal extension. High-quality products will improve the overall style and performance of the door in terms of appearance, internal quality, or later use. Wrapped seals are a modern development trend. Where can wrap seals be used? Wooden windows, aluminum clad wood, aluminum alloy doors and windows, wooden doors, wood-plastic doors, ecological doors, log doors, solid wood doors, painted doors, oak doors, composite doors, suit doors, security doors, sliding doors, wardrobe doors, cabinet doors, Bronze doors, cast aluminum doors, plastic steel doors and windows, 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. Silicone extruder information Excellent weather resistance and aging resistance, ozone resistance, chemical corrosion resistance, foam flexible sealing strip, excellent cold and heat resistance (-50℃~+170℃), super elasticity, 200% Stretching, high quality and low price 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 strip, curtain wall sealing strip, etc. Under normal circumstances, EPDM sealing strips can be used stably for more than ten years. With the continuous development and maturity of thermoplastic elastomer (TPE) technology, the application areas continue to expand. According to the classification of vulcanization (1) Discontinuous vulcanization (the extruded rubber strip is After a certain length is cut, put it in a vulcanizing tank, and put the extruded semi-finished rubber strip into the model to vulcanize); (2) Continuous vulcanization method (microwave continuous vulcanization method, salt bath continuous vulcanization method, hot air continuous vulcanization method, etc.) Several methods). The product is environmentally friendly, easy to construct, and has good anti-seepage, anti-leakage and water-stop effects. 2) Corrosion resistance, aging resistance, high and low temperature resistance +80℃~-45℃, no flow, no deformation, no embrittlement, long service life, thermoplastic EPDM rubber sealing strip The sealing strip is a new material developed on the basis of imported technology and domestic independent research and development in recent years. It is mainly used for automotive door and window sealing strips. In recent years, it has been used for building door and window sealing. Its outstanding advantages are: ①The performance and service life are equivalent to those of vulcanized EPDM rubber sealing strips.
An increasing dependence on the use of rubber seal strip suppliers custom sealing strip has made numerous changes in the custom sealing strip industry over the past decades.
have become more diverse in appearance and function thanks to the advanced technology. Choose a that you can trust to deliver an excellent user experience reliable performance at Kenna Rubber & Plastic.
You will have a custom sealing strip that looks custom sealing strip all the time, Because your is handling with it.
