Silicone shaped strips Dongguan production plant

Silicone special-shaped strips Dongguan production plant, car sealing strips are also something that can often be used in cars. In use, they use better quality products, so they can be used for a longer time. Although there are many brands on the market to choose from, But you still have to choose according to your actual situation, because different cars are suitable for different sealing strips, so you can choose more to compare above, how to use the sealing strip is worth our attention, and we also need to remember. Especially in the hot season, try to use it in a cool place to avoid exposure to the sun. 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 special-shaped strip Dongguan production plant. Second, after the sealing strip is damaged, it is easy for rainwater to enter the car. This phenomenon will cause damage to the car body, and it is easy to cause the car body to rust. We can see from this point. Although the product such as the seal is a small object, it is also an indispensable part for the car. When the automobile seal is intact, it can effectively reduce the wind noise caused by high-speed driving, and It also improves the air tightness and dust-proof effect of the car. It can be seen that regular maintenance of the sealing strip is very important. 2. At the same time, put the silicone rubber sealing strip at high temperature for a period of time (placed on the roof or in a sunny place), the PVC sealing strip will become very soft in a short time, the grease on the surface of the sealing strip will be deposited, contaminated with dust, and Yellowing (oil is easy to absorb soil) seepage, dirty hands; the physical properties of silicone rubber sealing strips have no change, the pressure cooker sealing ring for household use is silicone rubber, which uses the high temperature resistance, non-toxic and environmental protection of silicone rubber Performance: There is no obvious change in physical properties of silicone rubber in a working environment of 200°C. It is divided into self-adhesive type and card slot type. It is used in different doors and windows. It is more convenient and feasible in operation and installation. What is the performance advantage of the coated sealing strip? 1. Compression deformation test: 50% compression rate at 70℃ continuous compression 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. Thermal conductivity K value test: K value ≤ 0 at 0°C. 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. Silicone special-shaped strip Dongguan production plant B, salt bath continuous vulcanization sealing strip: salt bath vulcanization adopts a salt bath system containing nitrite, which has a large environmental pollution and has been gradually eliminated. C can be divided into solid cores according to the shape of the section. Products (round, square, flat cross-sectional shape), hollow products and metal rubber composite products, etc. EPDM rubber sealing strips are much stronger than PVC strips in terms of sealing elasticity and durability, but due to the need for microwave The vulcanization line is shaped and the processing energy consumption is high, usually more than 20 times that of PVC processing. The product cannot be reused, is not environmentally friendly, and is not an advocated product. 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. Second, high heat insulation. In the process of use, it has good heat insulation, which greatly reduces the thermal conductivity. Therefore, the heat insulation of this product is very good, which can effectively prevent the loss of temperature. 3. The demand for rubber sealing strips in the automobile industry is very large. Some electronic parts and electrical assembly parts are needed, such as the sealing of windshields and automobile windows, as well as the outer skin of high-voltage lines. There are spark plug protection covers and many other places. 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.
