Thermoplastic functional elastomers (TPE) are a type of high-performance polymer material that combines the elasticity and flexibility of traditional vulcanized rubber with the ease of processing of thermoplastic plastics. TPE exhibits high elasticity of rubber at room temperature and can melt and flow like plastic at high temperatures. It can be rapidly molded through injection molding, extrusion, and other processes without the need for vulcanization, making it an efficient and environmentally friendly material; Green” Material Science.
This series of products offers a variety of grades ranging from general grade to special functional to meet the application needs of different industries.
(1) Product Features
1、 Excellent elasticity and softness: comfortable touch, good resilience, and can provide a wide range of hardness.
2、 Easy processing and high efficiency: significantly simplifies production processes, shortens process time, improves production efficiency, reduces production costs, and enhances performance ratio.
3、 Excellent weather resistance and chemical resistance: It has excellent high and low temperature performance and wide temperature use range, and has good anti-aging, ozone, and common chemical reagents.
4、 Excellent coloring ability: can be adjusted to various bright and permanent colors without the need for spraying, reducing costs and VOC emissions.
5、 Good sealing and shock absorption: providing reliable anti slip, shock absorption, and sealing effects, widely used in handheld tools, seals, shock pads, etc.
6、 Environmentally friendly and non-toxic: The odor meets the requirements of level 3 or below.
7、 Adhesive with various materials: Some grades can achieve secondary encapsulation molding with hard plastics such as PP, ABS, PC, PA during injection molding, forming a strong bond and simplifying the product assembly process.
