The rapid development trend of the automobile industry and the continuous improvement of the application of automobile technology in my country have prompted everyone to put forward higher standards for its comfort, and automobile sealing strips play a key role in this. Since the tightness of the body is a key indicator for evaluating the characteristics of the entire vehicle, today's manufacturers attach great importance to the improvement of automotive sealing strip technology. The following small series to tell the importance of choosing the method of car sealing strip.
The rapid development trend of the automobile industry and the continuous improvement of the application of automobile technology in my country have prompted everyone to put forward higher standards for its comfort, and automobile sealing strips play a key role in this. Since the tightness of the body is a key indicator for evaluating the characteristics of the entire vehicle, today's manufacturers attach great importance to the improvement of automotive sealing strip technology. The following small series to tell the importance of choosing the method of car sealing strip.
The automobile sealing strip is a special rubber sealing strip system, which can ensure the sealing performance. It has excellent waterproof, dustproof, windproof, shock absorption, noise reduction, heat preservation, heat insulation and other characteristics. It can be said that the automobile sealing strip has now become an independent and key industry in the automobile related industry.
The automobile sealing strip occupies a key influence in the parts. Its production process and the characteristics of the automobile sealing strip are not hardened and brittle in the low temperature test of -40, but still maintain softness and good adhesive tape adhesion, showing Excellent cold resistance.
The automobile sealing strip is mainly made of EPDM rubber with good elasticity, compression deformation resistance, aging resistance, ozone chemical resistance, and a wide temperature range (-40~120). It is foamed and compacted. It contains a unique metal clip And tongue-shaped buckle, so it is durable and easy to install.
The performance of automobile sealing strip directly affects personal safety. For example, a partial recall of a model sold in previous years has had serious credit consequences. Therefore, all manufacturers need a rubber product with long-term stable performance and sufficient safety. At present, the low temperature performance of rubber products in the market is generally around -25, but the rubber parts on the car cannot withstand the cold airflow in the harsh local environment, which greatly reduces the product life.
Any product is easily damaged during use. In order to reduce the probability of this phenomenon, the product needs to be effectively maintained. Because of its excellent physical and mechanical properties, it is often used in the manufacture of aluminum alloy insulation window seals for high and low voltage switch cabinets of aircraft, automobiles, trains, buses, ships, high pressure steam hoses, tunnels, viaducts and other industrial and agricultural seals.
Automobile sealing strip is mainly used for automobile doors and windows. It is extruded from ethylene propylene diene monomer rubber (EPDM) with good elasticity, compression deformation resistance, aging resistance, ozone, chemical action and wide service temperature range (-40 ℃ ~ 120 ℃). With good impact resistance, many people have to use foam sealing strips as cushioning materials, because the impact resistance of such products is very good, the physiological stability of rubber car sealing strips is very good, and the deformation resistance is also very strong. It is not only anti-ozone, but also has good anti-ultraviolet performance, so this kind of product has been widely used, and it is indispensable in many places such as medical shunt, electronics, wire and cable. There is also a very good advantage, is the long service life.
