In simple terms, thermoplastic elastomers are thermoformed, and some products can be produced with injection molding machines, extruders, and blow molding machines! It has the function that the nozzle can be 100% recycled and part of traditional rubber! However, some mechanical properties and anti-aging properties are far inferior to rubber, such as automobile tires, thermoplastic elastomers cannot do it, only natural rubber can do it!
Thermoplastic elastomers can be bonded with PP, PC, ABS, PS, PE, PA and other hard adhesives, and are generally used in some auto parts, daily necessities, sporting goods, children's toys and kitchen supplies, etc., and are often used on toothbrush handles. Soft rubber is thermoplastic elastomer (TPE)
1. Thermoplastic elastomer is a linear structure, which is physically cross-linked through hydrogen bonds, and the hydrogen bonds are broken at high temperature, making it plastic; rubber is chemically cross-linked and has no thermoplastic properties.
2. Rubber is soft, and thermoplastic elastomers have a wide range of hardness, between rubber and plastic.
3. The processing methods are different. Rubber is processed by rubber mixing, and thermoplastic elastomers are generally processed by extrusion.
4. Different properties, rubber usually needs to add various additives and needs vulcanization reinforcement, while thermoplastic elastomers have good performance
5. The concept of elastomer is wide, thermoplastic elastomer is also called thermoplastic rubber, rubber usually refers to thermosetting rubber
