Nylon (PA) has a series of excellent properties such as high mechanical strength, chemical resistance, oil resistance, wear resistance, self-lubricating, and easy processing and molding, and has become one of the widely used thermoplastic engineering plastics both domestically and internationally.

Thermoplastic elastomers, abbreviated as TPE or TPR, are also referred to by many as SBS, a specific type of elastomer. But in reality, there is no unified name for thermoplastic elastomers both domestically and internationally, and most of the time they are represented by the English abbreviation TPE.

Thermoplastic elastomer is an environmentally friendly low-carbon composite material that possesses the characteristics of rubber (high elasticity, compression permanent deformation, etc.), as well as the processing characteristics of plastic (simple process). In most regions, the abbreviation TPE is commonly used to refer to thermoplastic elastomers. Another theory is that TPE is the general term for thermoplastic elastomers, TPU is thermoplastic polyurethane, TPV vulcanized thermoplastic elastomers, and TPR is generally considered as shoe sole material in China.

PU is the general term for polyurethane, while TPU is a thermoplastic polyurethane elastomer. TPE is a polyolefin elastomer, while TPU is a polyurethane elastomer. TPU has much better wear resistance, and its hardness can be very low.

The main methods for implementing grafting reactions include solution method, melting method, solid-phase method, and radiation grafting method.

Injecting TPE materials requires strict control of temperature, pressure, injection speed, and other process parameters to ensure the production of high-quality finished products. Meanwhile, appropriate mold design and equipment maintenance are also key factors to ensure successful processing of TPE.

PE has excellent mechanical processing performance, but its surface is inert and non-polar, resulting in poor printability, dyeing, hydrophilicity, adhesion, anti-static performance, and compatibility with other polar polymers and inorganic fillers. In addition, its wear resistance, chemical resistance, environmental stress cracking resistance, and heat resistance are poor, limiting its application range. Modification is needed to improve its performance and expand its application field.

Nylon and glass fiber injection molding generally use glass fiber modified raw materials. Has good rigidity and is a leader in rigid materials. However, we often encounter a phenomenon: what if high rigidity raw materials have poor impact resistance?
