Top seal silicone strip

The top-seal silica gel strip can be used at 100-120℃ for a long time, and it can maintain effective physical properties for a long period of time at 140-150℃. It can withstand high temperature of 230-260℃ in a short time, which is sudden to urban construction. In the event of an accident, it can play a delay role; coupled with the use of special formulas, EPDM rubber feels similar at -50°C to 150°C, which creates a high-efficiency work performance for installation on the production site 3. C has excellent ozone resistance and is also known as 'crack-free rubber'. It is especially used in various urban buildings with different atmospheric indexes and completely exposed to the air, and it will show the superiority of its products; 4. Anti-ultraviolet radiation provides environmental protection for residents of high-rise buildings; it can withstand voltages of 60~150KV, corona resistance, electric crack resistance, and arc resistance, which are also very good. 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. Top seal silicone strips are classified according to materials. The rubber materials of automobile sealing strips are compact rubber, sponge rubber and hard rubber. The hardness of hard rubber can reach Shore A95. EPDM can be combined with steel belt, steel wire braided belt, TPE, flannel , Flocking, PU coating, organic silicon coating, etc., to ensure the waterproof, dustproof, sound insulation, heat insulation, vibration reduction, anti-wear and decorative effects of the car interior and the outside world and itself, and it can also choose to have good ozone resistance And chloroprene rubber (CR) with good aging resistance. The function of the sealing strip is to improve the airtightness and prevent wind and rain from entering the car. In order to avoid the occurrence of the above, the sealing strip must be maintained regularly. 5. Because of its excellent physical and mechanical properties, it is often used in manufacturing Airplanes, cars, trains, passenger cars, ships, high and low voltage switch cabinets, glass curtain walls, aluminum alloy heat-insulating window sealing parts and diving products, high-pressure steam hoses, tunnels, viaduct joints and other waterproof parts and other industrial and agricultural sealing parts. Durable. It maintains stable performance and long service life in different environments. It is anti-aging, wear-resistant, non-wrinkle, non-stretching, non-stick paint surface, not affected by high temperature, dust, mildew resistance Ultraviolet and ozone erosion, our value to you starts from your experience. It is durable and lasting. It is the real experience of users. The beautiful coated PU sealing strip is green and environmentally friendly and stylishly sealed; it perfectly solves the contradiction between sealing and sound insulation , To achieve the dual effects of sealing and sound insulation; doors and windows perfectly match the product. 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.

Ensure personal safety. Top-seal silicone strips are also called fire-resistant silicone sealing strips and fire-resistant self-extinguishing silicone sealing strips. They are known for their good flame-retardant and self-extinguishing properties. The main process is to first use high-quality silicone materials to make moldings through a large extruder. Silicone strips are then made through high room temperature vulcanization and drying. Compared with ordinary silicone strips, the difference between high temperature resistant and flame-retardant silicone strips is that it needs to add flame retardant powder to the formula. The strip has super flame-retardant and fireproof performance, and it also plays a certain safety guarantee in the sealing of electronic appliances, so many people also call it a fire-proof sealing strip. 6) Classification and function, high-quality sealing strips will improve the overall style and performance of the door in terms of appearance, internal quality, or later use, and covered sealing strips are the modern development trend, and the humanized 'past' Traditional sealing strips have always paid more attention to materials and workmanship, ignoring the attention to humanization in use. With the improvement of people’s living standards, the improvement of housing conditions and people’s high attention to home decoration, the privacy of indoor rooms, More and more people pay attention to the sound insulation and sealing effect. The expensive one is 15,000 yuan and 6,000 yuan per ton, and the cheap one is only 6,000 yuan per ton. The price difference is nearly 10,000 yuan, and the quality difference is very large. It is confusing and many seals. All manufacturers claim that their products are in compliance with the GB12002-89 standard, and can issue test reports qualified by authoritative organizations. Sealing strips are classified 1, 2, according to the surface treatment state, and some of the sealing strips can be divided into flocking after additional treatment. Class sealing strip; surface coating sealing strip; with fabric patch sealing strip.
