Prospect Analysis Of TPE.TPR Material Application Field

Main applications and prospects of TPR/TPE:


    Application of thermoplastic elastomer TPR/TPE in the footwear industry: The sole made of SBS instead of vulcanized rubber and polyvinyl chloride has good elasticity (low stress or residual distortion), beautiful color, good wet skid resistance, breathability, and resistance to abrasion. Grinding, low temperature and bending resistance, not stinky feet, wearing comfort, etc., have higher friction coefficient on asphalt pavement, moisture and snow-covered road surface. Waste SBS soles can be recycled and used at a moderate cost. The sole pattern can be a semi-transparent beef bottom or a colorful two-tone sole, or a foamed sole. The cheap integral molded canvas shoes made of SBS are 15-25% lighter than PVC shoes and have a 30% higher coefficient of friction, and have excellent abrasion resistance and low temperature flexibility. SBS has these excellent properties, making it widely used in the footwear industry. China is the world's largest producer of footwear products and the largest consumer market for footwear products. In a certain period of time, the footwear market will continue to be the main target market for domestic SBS. After China's accession to the WTO, the export quota for footwear will be abolished and the export advantages will be fully utilized. In order to eliminate the imbalance in the development of the eastern and western regions, the state has begun to increase investment in the western region in order to accelerate its economic development. In the next few years, with the economic take-off of the western region and the rising living standards of the people, the demand for shoes based on TPR (pellets for SBS footwear) will increase year by year.

 

The application of thermoplastic elastomer TPR/TPE in asphalt modification: The application of SBS in asphalt modification includes the modification of waterproof membrane asphalt and the modification of road asphalt. The bitumen waterproofing membrane modified by SBS has the characteristics of good low temperature flexibility, good self-healing ability and durability, high temperature flow resistance, aging resistance, good thermal stability and impact resistance, and can greatly improve the performance of the waterproof membrane. , to extend its service life, to meet the needs of important buildings and structures. It has been widely used in municipal engineering including bridge decks (concrete), subways and underground passages, and water conservancy projects including ponds and canals. At present, there are many manufacturers of modified bitumen membranes in China, among which there are 15 modified bitumen membranes imported and put into operation. There are more than 50 domestically developed production lines with a total production capacity of approximately 140 million m 2 /year, 2003. The actual consumption of SBS is about 63,700 tons. With the massive investment in infrastructure construction in China and the acceleration of construction, China's modified asphalt has a good development prospect, and accordingly, the demand for SBS will increase. It is estimated that by 2008, the consumption of SBS in the modified asphalt field will reach 112,000 tons, and the average growth rate from 2003 to 2008 will be about 12%.

 

Thermoplastic elastomer TPR/TPE in polymer modification applications: SBS is a good resin modifier, can be blended with PP, PE, PS, ABS and other resins to improve the impact resistance and flexing performance of the products. This type of product is mostly used in electrical components, car steering wheels, bumpers, seals, etc. Compared with developed countries and regions in foreign countries, China's polymer modification industry is still in its infancy. In 2003, the consumption of SBS in polymer modification in China was about 16,500 tons. With the development of China's automobile industry and home appliance industry, consumer demand for performance, safety, durability and other performance will gradually increase, coupled with the rapid development of China's synthetic resin industry, the domestic polymer modification industry will be booming development of. It is estimated that by 2003-2008, the application of polymer modified SBS products in China will grow at a rate of more than 20% and will reach a level of 45,000 tons by 2008.

 

Thermoplastic elastomer TPR/TPE in the application of the adhesive: Because SBS has good solubility in hydrocarbon solvents, fast dissolution, good stability, strong cohesion, avoiding the harm of human health with aromatic hydrocarbon solvents. In addition to the good elasticity, adhesive strength and low temperature performance of SBS adhesive, its low viscosity and creep resistance are better than those of general EVA and acrylic adhesives, and it has been widely used in daily life. It can be used in the production of shoe adhesives, metallurgical powder molding agents, silicone adhesives, wood quick-drying adhesives, labels, adhesive tapes, disposable sanitary products, laminating adhesives, sealants and hooks. Electronic components and generally strong plastic, adhesive and stickers and so on. In 2003, China's adhesive industry actually consumed about 43,700 tons of SBS. It is estimated that by 2008, the demand will reach 87,000 tons, and the average annual growth rate of demand in 2003-2008 will be about 14.7%.

 

Application of thermoplastic elastomer TPR/TPE in other fields: SBS can also be used as the main raw material for toys, furniture and sports equipment; as a flooring material, automotive upholstery material, carpet bottom layer and sound insulation material, and wire and cable sheathing. In addition, SBS can also be used in cement processing, automotive manufacturing and interior decoration, as well as the manufacture of various hoses for light oil, medical devices, household appliances, pipe strips, and wire and cable. In other areas in 2003, the domestic consumption of SBS was approximately 13,100 tons. It is expected to reach 50,000 tons by 2008, with an average annual growth rate of more than 30%.
