Picture of silicone anti-slip rubber strip
s, car sealing strip
s can be classified into solid core products (round, square, flat cross-section shapes), hollow products and metal rubber composite products according to the cross-sectional shape. Second, the three-dimensional heat aging resistance Ethylene-propylene sealing strips have been tested many times before production. From the experiments, it can be seen that the product can continue to work in a high-temperature environment without aging. Therefore, many companies use the product to improve Work efficiency, so as to get more profits. 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. Silicone anti-slip tape pictures Actually, we cannot do without this product in many places in our lives, because its use effect is very good, friends who don’t know can take a look at the EPDM seal with me The characteristics of the strip. Third, the ozone resistance of the ozone resistance product is very good. It can be completely exposed to the air to work, so that the superiority of the product is more prominent, and the EPDM sealing strip is resistant to ultraviolet radiation. The effect is also very good, and it also has excellent physical and mechanical properties, so it is often used to make airplanes, trains, cars, and so on. It is used to maintain the door, window glass, front and rear windows, triangular windows and other parts of the body. Its better maintenance ensures safe and comfortable driving. However, few car owners pay attention to its maintenance, but in fact its maintenance is very It’s important because once it’s aging and damaged, it will cause rain leaks in the cabin and increase the wind noise of the car. Rain leaks can easily corrode the body. We can keep the car sheltered from wind, rain, dust and heat by maintaining it. , The effect of sound insulation, and when the body is shaken and twisted, it also plays a role in buffering, absorbing shock and retaining glass. It also plays a decorative role on the edge of the door and window junction, so the owner must maintain it frequently. With the improvement of people's living standards, the improvement of housing conditions and people's high attention to home decoration, more and more people pay attention to the privacy, sound insulation and sealing effect of indoor rooms, 035W/m2K; 5. Fatigue resistance test: imitation The window has been opened and closed 500,000 times without significant changes in shape. 6. Sound insulation test: only IV68 windows with intermediate rubber strips, reducing noise by 43 decibels7, IV76 windows with intermediate rubber strips and additional rubber strips, reducing noise by 45 decibels8, Outdoor aging resistance test: It has been more than 20 years, and the performance is maintained intact. The series of products are environmentally friendly products and do not contain CFC harmful substances. 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. Doors and windows bring light and vitality to the room. Doors and windows extend the limited space infinitely. Said ternary bc sealing strip (rubber EPDM)-suitable for special environment of -40℃-+160℃, It has superior anti-ozone characteristics, purple light reflection characteristics and chemical solvent resistance characteristics, which are far beyond similar products. It is widely used in vehicle seals and building seals. In addition to various physical and chemical performance indicators in the field, our company has developed and designed different use The Hardy and heat of the field combine to send foam and solid, with special properties that can meet the needs of the application. Humanization 'In the past, the tradition has always paid more attention to materials and workmanship, ignoring the attention to humanization in use. What are the performance advantages of coated seals? 1. Compression deformation test: 50% compression rate at 70°C continues to compress 22 hours, deformation rate≤10%2, compression force test, under 25% compression rate, apply a force of 15N/100mm, compression rate≤10N3, temperature range test: from -40℃ to 90℃, the sealing performance is not obvious Change 4. Heat conduction K value test: K value ≤ 0 at 0℃. Sealing strip is a very important part of doors and windows. It can not only ensure the watertightness of doors and windows, but also reduce sound insulation. At the same time, it can also be protected by external forces. However, due to the usual Sunlight will cause aging, shrinkage or deformation, so we have to check regularly and look at the specific gravity. If it is of good quality, the weight will be light, if it is a defective product, the weight will be heavier. This is because the regular manufacturers will use calcium carbonate as a filling. Some manufacturers use talcum powder to increase the weight of their products, so we can easily distinguish good products from inferior products by looking at the specific gravity when buying.
