What is the Difference Between Neoprene and Polyethylene Gaskets?

Rubber-based gaskets, usually we see transparent rubber pads, EVA rubber pads, EVA foot pads, round foot pads, semi-circular transparent foot pads, rubber pads, silicone pads, rubber pads, PU, PVC, EPDM transparent pad, hemispherical foot pad, hemispherical rubber pad, glass pad, bumper pad, non-slip pad, shock pad, anti-corrosion pad, waterproof pad, sponge pad, foam pad, etc.

Oil resistance is a very important characteristic of rubber materials. In many cases, rubber pads need to be used in the environment of various oily media. Oil resistance is a very important parameter of rubber pads, but the oil resistance of various rubber materials also has Different, will be described in detail below

Fuel resistance: FKM and FMVQ have the best resistance to fuel oil. And neoprene and chlorinated polyethylene rubber CPE have the worst fuel resistance.

The fuel resistance of NBR increased with the increase of acrylic content. Chlorohydrin rubber has better fuel resistance than nitrile rubber.

Resistance to mixed fuel: Fluorosilicone rubber FMVQ and fluorine rubber FKM have the best resistance to mixed fuel oil. Acrylic rubber has the worst resistance to mixed fuels.

The resistance of NBR to mixed fuel increases with the increase in acrylic content.

High in fluorine

The rubber industry is one of the important basic industries of the national economy. It not only provides people with daily-use, medical and other light industrial rubber products that are indispensable for daily life, but also provides various rubber production equipment or rubber components to heavy industries and emerging industries such as mining, transportation, construction, machinery, and electronics. It can be seen that the rubber industry has a wide range of products and the backward industry is very broad.

In recent years, the rubber industry has developed a lot. The existing sub-sectors have steadily increased, and the new rubber sub-sectors have developed rapidly. At the same time, the rubber industry also has problems such as environment, resources, disasters, and innovation.

In 2004, the total area of natural rubber planting in the country was 696,200 hectares, the area of cutting was 459,900 hectares, and the dry rubber output was 573,300 tons. Among them, 411,000 hectares of rubber are cultivated in agricultural land and 285,200 hectares are privately owned, accounting for 59.03% and 40.97% of the total rubber area of the country.

In 2005, Hainan suffered a rare drought of 50 years and a typhoon disaster not encountered in a century, and natural rubber production was hit hard. In order to tap the development potential of domestic natural rubber planting and processing, and increase self-sufficiency, the Chinese rubber industry has made unremitting efforts, conscientiously implemented the national security, energy saving, environmental protection and cleaner production policies, and achieved significant results. In particular, the rubber additive industry has actively adjusted its product structure. Green environmentally-friendly additives have grown significantly. The output ratio of excellent varieties of antioxidants has reached 80%, and the promoter has reached 50%. The production of toxic, harmful and highly carcinogenic NOBS has been effectively controlled; The comprehensive utilization rate of waste rubber has reached more than 65%, and the field of post-processing and utilization of recycled rubber and rubber powder has expanded.

In 2006, the Third Session of the Sixth Council of the China Rubber Industry Association discussed and issued the "Eleventh Five-Year Plan Scientific Development Plan Opinions of the Chinese Rubber Industry" and the "11th Five-Year Plan" Opinions on the Implementation of Famous Brands in the Rubber Industry. This is the first industry plan formulated by the association. The plan shows that the rubber industry must take the road of independent innovation during the "Eleventh Five-Year Plan" period, and the entire industry must effectively turn to the track of scientific development, so that China will become a strong country in the rubber industry in the world.

China's rubber industry has broad prospects for development. By 2010, China's total consumption of natural rubber will reach 2.3 million tons, and the product structure of the rubber industry will undergo significant changes. New products, replacement products will increase, new materials and new processes will be expanded, and production technology will significantly improve.

The characteristics of the rubber industry determine that when a country's rubber industry matures, the prosperity of the industry and the operation of the entire economy will maintain a strong correlation: the length of its development cycle is equivalent to the length of the country's economic cycle, and the trend However, since the rubber industry is a basic industry, its cyclical change should be slightly ahead of the economic cycle. In addition, because the rubber industry is at the forefront of the national economic production chain, its periodic fluctuations are less than the fluctuations of industries at the end of the industrial chain, and less than the fluctuations of the entire economy. Therefore, from the perspective of industrial investment, the mature rubber industry is closer to the income-based investment industry.
