Silicone round strips are connected to form a sealing ring, which is mainly used in the door leaf door frame, side window, front and rear windshield, engine cover and trunk cover, which play a role in waterproof, dustproof, sound insulation, temperature insulation, shock absorption, and decoration. The unique formula design makes EPDM rubber seals have excellent anti-aging, high and low temperature resistance and chemical resistance performance, good elasticity and compression deformation resistance, and will not crack or deform after long-term use. It can maintain its original high sealing performance between -50 degrees and 120 degrees. 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 round strips are connected into a sealing ring to prevent collisions. There will be 'bumps! Bumps!...' when you close the door and cabinet doors for countless times. Will it affect your mood and mood every day? New PU foam sealing strip
s , Has super resilience, no deformation, tasteless and environmental protection, sound insulation and anti-collision effect is more obvious, it is worth having, 5) EPDM rubber material 40°F-248°f (-40°C-120°C), nitrile- Butadiene rubber material is 40°F-248°f (-40°C-120°C), silicone rubber material is 40°F-260°f (-40°C-126. And this EPDM sealing strip is on the design , Is often more advanced, it has an independent bubble structure, so that it can form a good sealing bond rate, all the bubbles have reached a uniform distribution, can play a good expansion and contraction Performance. It is precisely because of this that it can achieve the superior performance of no flow, no deformation, no cracking, etc., and it cannot be combined with many uneven substances on the contact material used except for the plane. 4. Good impact resistance. Many people want to use foam sealing strips as cushioning materials, because the impact resistance of this product is very good, the physiological stability of the rubber sealing strips is very good, and the resistance to deformation is also very strong. Yes, it is not only resistant to ozone but also very resistant to ultraviolet rays, so this product has been widely used, and it is inseparable from many places such as medical diversion, electronics, wire and cable, etc. This product also has a very good advantage, that is, long service life. 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 and has a relatively harsh climate. Under the local environment, it can withstand the invasion of cold air and ensure good performance, thereby ensuring personal safety. Technical realization elements: The technical problem to be solved by the present invention is to provide a rubber formula for automobile products and a preparation method thereof. In a harsh climate, it can withstand the invasion of cold air to ensure good performance and ensure personal safety. Silicone round strips are connected to seals and energy-saving doors and windows are roughly composed of profiles, hardware, glass and EPDM door and window sealing strips, and The processing technology is composed of several modules. The sealing strip has a lower cost due to its lower proportion and the influence of some traditional concepts that do not pay attention to the energy-saving standards of doors and windows. It has been ignored by many door and window manufacturers, but we cannot but admit the sealing strip It plays a vital role in door and window systems. What important role can EPDM sealing strips play in door and window systems? For car sealing strips, we must pay more attention to maintenance and master the correct maintenance methods. Otherwise, The maintenance effect cannot be achieved. Let’s take a look at the importance of car sealing strip maintenance. The characteristics of the product The elasticity and compression resistance of the car sealing strip are very good, and it also has good resistance to aging and Ozone and chemical effects, etc., make the product very strong and durable during use, and it is also very convenient to install. It plays a key role in the electrical cabinet. The frame seal is composed of dense rubber, foam rubber and steel wire film. The cabinet sealing strip is mainly used for cabinets, electrical cabinets, and machinery. It is mainly used for fixing effects and sound insulation, waterproof, dustproof, and sealing. Recommended temperature Scope: PVC material 20°F-150°f(-29c-65, a door can not be beautiful, but a sealing strip must be installed to ensure sound insulation, temperature and sealing performance
