Analysis On China's Synthetic Rubber Industry In 2021
1. Synthetic rubber applications
Synthetic rubber, also known as synthetic, is one of the polymers made by artificial synthesis. Its production is only lower than synthetic resin (or plastic), synthetic fiber. Rubber is a material necessary for the manufacture of aircraft, warships, automobiles, tractors, harvesters, water drainage and irrigation machinery, medical equipment, etc. Rubber can be divided into and synthetic rubber. There are a few varieties of synthetic rubber with similar properties to natural rubber, most of them are different from natural rubber, but both are highly elastic polymer materials, which generally need to be vulcanized and processed before they have practicality and use value.
2. Synthetic rubber production
In recent years, the development trend of China's synthetic rubber industry is gratifying. With the continuous expansion of production scale, synthetic rubber industry will occupy a more important position in China's industrial economy. Through several years of development, the domestic synthetic rubber industry has made great progress. Both annual production and consumption have been squeezed into the forefront of the world. 2021 China's synthetic rubber production was 8.117 million tons, up 9.8% year-on-year. 、
3. The import and export of synthetic rubber
In recent years, China's synthetic rubber production capacity has increased rapidly, but it fails to fundamentally meet the huge domestic demand, and the annual import volume is still large. 2021 China's synthetic rubber import volume is 4.385 million tons, and export volume is 606,000 tons. According to China Customs data, the import amount of synthetic rubber in China in 2021 was $8,272,670,000, down 14.1% year-on-year; the export amount of synthetic rubber was $135,547,000, up 67.3% year-on-year.
Synthetic rubber materials also have excellent heat resistance, cold resistance, corrosion resistance and are less affected by environmental factors. The average unit price of China's synthetic rubber imports in 2021 is US$1,886.58/ton; the average unit price of exports is US$2,236.75/ton.
Ethylene propylene rubber is a synthetic rubber with ethylene and propylene as the main monomers, based on the different composition of monomers in the molecular chain, there are binary ethylene propylene rubber and tertiary ethylene propylene rubber, the former is a copolymer of ethylene and propylene, expressed as EPM, and the latter is a copolymer of ethylene, propylene and a small amount of non-conjugated diolefin third monomer, expressed as EPM.
In 2021, China's ethylene propylene rubber imports amounted to 169,000 tons, down 92.1% year-on-year, and the import amount was $410.43 million, down 83% year-on-year; China's ethylene propylene rubber exports amounted to 32,000 tons, down 54.9% year-on-year, and the export amount was $83.44 million, down 26% year-on-year.
Chloroprene rubber is produced from (i.e., 2-chloro-1,3-butadiene) as the main raw material for alpha polymerization, and is widely used in weather-resistant products, adhesive shoe soles, coatings and rocket fuel. 2021 China's chloroprene rubber imports amounted to 22,000 tons, up 10% year-on-year, with an import value of $92.85 million, up 16.6%; chloroprene rubber exports amounted to 15,000 tons year-on-year growth of 36.4%, the export value of $ 61.21 million, an increase of 53%.
Butadiene rubber is also known as polystyrene butadiene copolymer. Its physical properties, processing properties and the use of products close to natural rubber, some properties such as wear resistance, heat resistance, aging resistance and vulcanization speed is more excellent than natural rubber, can be used with natural rubber and a variety of synthetic rubber, widely used in tires, tapes, hoses, wires and cables, appliances and various rubber products production and other fields, is the largest general synthetic rubber species, but also the earliest to achieve In 2021, China's imports of styrene butadiene rubber amounted to 515,000 tons, down 6% year-on-year, and the import amount was 108,301,000 U.S. dollars, up 30.8% year-on-year; exports of styrene butadiene rubber amounted to 118,000 tons, up 26.9% year-on-year, and the export amount was 210,107,000 U.S. dollars, up 62.8% year-on-year.
NBR is made of and monomer polymerization, mainly using low-temperature emulsion polymerization method of production, excellent oil resistance, high abrasion resistance, heat resistance is better, strong adhesion. Its disadvantages are poor low-temperature resistance, poor ozone resistance, poor insulation performance, and slightly lower elasticity. 2021 China's nitrile rubber imports amounted to 245,000 tons, up 25.6% year-on-year, and the import amount was $583.64 million, up 87.6%; nitrile rubber exports amounted to 150,000 tons, up 141.9% year-on-year, and the export amount was $342.64 million, up 158.5%.
Butyl rubber is synthesized from isobutylene and a small amount. It is generally used in the production. In the field, butyl rubber to of has been fully popular instead. 2021 China's butyl rubber imports amounted to 218,000 tons, down 23.2% year-on-year, and the import amount was $476.67 million, down 13.3% year-on-year.
