Overview

Thermoplastics elastomer (Thermoplastics elastomer), referred to as TPE. TPE also has the functions and properties of traditional thermoplastic rubber (softness, elasticity, and good touch). It also has the dual advantages of simple processing, fast speed and recyclability of general thermoplastics. It is a polymer material that has the properties of vulcanized rubber (that is, the properties of an elastomer) at room temperature, and can be plastically deformed at an appropriate temperature. It can be molded by plastic processing machines. After natural rubber and synthetic rubber, the so-called third-generation rubber is referred to as TPE. It is also referred to as thermoplastic rubber (Thermoplastis.rubber), referred to as TPR due to its functions and properties.

Thermoplastic elastomers (TPE) can be summarized into two types: general TPE and engineering TPE. At present, it has developed into 10 categories and more than 30 varieties covering almost all areas of synthetic rubber and synthetic resins.

Processing and molding methods include injection molding, extrusion, and casting.

Advantage	Use	Application situation
Tensile strength, elasticity, friction resistance, fatigue resistance, low price and good quality	Rubber shoes, modified asphalt, synthetic resin modifiers, adhesives, toys and daily necessities	About 80% of the consumption is used in the footwear industry. At present, my country has become a major producer and exporter of footwear in the world. Every year, it needs to import a large amount of SBS products from Taiwan, South Korea, Japan and Russia.
Excellent bonding performance and good heat resistance	Adhesive field	90% is used in the field of adhesives, the main material of hot melt adhesives in Europe, America and Japan
The impact strength is greatly improved than SBS, and the weather resistance and heat aging resistance are also significantly improved than SES	SBS or SEBS is the base material and other engineering plastics to form IPN-TPS, which greatly improves the cold and heat resistance of engineering plastics, and is used in toys, medical devices and daily necessities.	It has better performance than SBS and can replace the application of SBS
Significant improvement in compression set resistance, heat aging resistance, oil resistance, etc.	The main applications in the automotive field are bumpers, dashboards, steering wheels, interior parts, fan covers, wheel covers and luggage, etc.; in the field of home appliances, there are wires and cables, household appliances, etc.	The application of TPO in automobiles involves nearly a hundred parts and components, and the amount of automobiles accounted for more than 75% of the total output. The importance and good prospects of TPO in automobiles and electronic and electrical applications have become the fastest growing type of TPE
Good wear resistance, low friction coefficient, simple coloring process	Automotive glass channel sealing strip, container, construction and other fields	TPV is expensive, and demand mainly depends on imports
High strength, good toughness, wear resistance, oil resistance and other excellent properties.	Gaskets, sealing rubber, shoe materials, sports goods, shock absorption materials, industrial casters, high-pressure tubing, conveyor belts, pipes, special-shaped materials, cable sheaths, gears, films, solid tires, brake pads, drive tires, rollers, etc. aspect.
Under low stress, its tensile stress is greater than other polymer products of the same hardness, so the wall thickness of the parts can be made thinner, and the low temperature toughness, chemical resistance, oil resistance, and good electrical insulation properties	Mainly used in airbag opening doors, heavy truck and off-road vehicle equipment parts, sealing rings, hoses and ducts, etc., in the fields of automobiles, home appliances, power tools, sporting goods, etc.
