Thermoplastic Elastomers Are Increasingly Used In Automobiles

Jan 24, 2020

Thermoplastic elastomers are increasingly used in automobiles

The thermoplastic elastomer is mainly divided into two methods: one is extrusion molding and the other is injection molding. Extrusion molding is rarely used. Manufacturing and processing thermoplastic elastomers through injection molding is fast and economical. Thermoplastic elastomers can also be processed by blow molding, thermoforming, and thermal welding. None of these methods can be applied to thermosetting rubber products. Therefore, the thermoplastic elastomer TPE / TPR industry has developed particularly quickly, especially in automotive applications, dual-material applications, bonding, etc., and its commercial status is becoming increasingly important.

    Taking the car as an example, it can be found in the body, interior parts, chassis, and engine periphery, and it has witnessed excellent performance in the severe test of the car. Thermoplastic elastomers have the advantage of being able to replace rubber and used in the modification of general thermoplastic resins such as PVC, PE, PP, PS, and even engineering plastics such as PU, PA, CA, so as to maintain the advantage of continued development.

    Among them, G172D thermoplastic elastomer has similar flexibility, elasticity and mechanical strength as rubber, but it has better heat resistance and weather resistance than rubber in the processing of plastic molds. All grades of KEYFLEX BT are block copolymers consisting of hard segments of polybutene-terephthalate and soft segments based on long-chain polyether glycol. It is widely used in automotive radiator and coolant hose and fuel quick-connect seals. The performance of thermoplastic elastomer tough materials can match many organic materials under severe working conditions. Plastic mold processing has a wide market potential and unlimited development space.
