Small size and large energy rubber seal for automobile protection
The modern automobile industry has put forward higher and higher requirements on sealing parts. It not only needs to have excellent sealing performance, but also needs to be beautiful, safe and environmentally friendly. Sealing performance has also become an important index to evaluate automobile quality, and automobile sealing parts have a promising development prospect.
The modern automotive industry hasincreasingly high requirements for sealing parts. Not only have excellentsealing abilities, the sealing parts must be aesthetically pleasing, safe andeco-friendly. Sealing performance has become an important indicator forappraising automobile quality.
In rubber industrial products, seal products are a kind of basic accessories with high technical content and multiple categories.
Sealing device is everywhere. Sealing technology should be at the forefront of other projects to protect the safety in all fields. "keeping leakage" will be the theme of eternal pursuit now and in the future.
According to the national bureau of statistics, the market size of the rubber seal in 2016 was around 14.98 billion yuan, while in 2017 it was around 16.8 billion yuan. The average annual compound growth rate of the industry market size from 2005 to 2017 was about 16.1 percent.
High performance rubber seals have great market potential
Rubber sealing strip is the fastest developing rubber product for automobile in recent years. It is widely used in door, window, body, skylight, engine box and trunk, and has the function of sound insulation, dustproof, water proof and shock absorbing.
With the rapid development of China's automobile industry, a huge market of high-performance rubber sealing parts has been created.
The rationality of the structure, the humanization of the design, the process and automation of the production process, the safety and environmental protection of the products, the recyclability of the products, the beauty of the supporting facilities and the diversity are all the product properties that should be considered by the enterprise of automobile rubber seal.
The technology of automobile sealing parts has been constantly updated, and some new materials, new processes and new equipment have been put into actual production.
Ethylene-propylene rubber used in automobile sponge sealing strip
At present, most of automobile sealing strip materials are mainly made of ethylene propylene rubber (EPDM) as the main raw material. With excellent weather resistance, heat resistance, ozone resistance, uv resistance, good processing performance and low compression permanent deformation, it is one of the first choice materials for producing sealing strip.
To take the lead in high-end markets such as automotive sponges, strict control must be exercised over product polymerization structure, polymerization purity, and even the structure of rubber gels.
Manufacturers must effectively make the high viscosity rubber into a uniform mixture, which is then extruded and cured into sealing strips.
Lanxess Keltan epdm can meet the high-tech automotive sponge rubber seal system, such as Keltan 4903, Keltan 7341A is known for its extremely high Mooney viscosity.
As the latest addition of Keltan family, Keltan 6251A has provided customers with unprecedented surface effect, supplying high-end automobile seals to audi, gm and other cars.
Along with people's attention to the automobile, the implicit request to the automobile accessory comes into being and more demands are put forward in the automobile sealing accessory.
In recent years, China's automotive rubber sealing industry has achieved a leapfrog growth, the future development will be unstoppable.
