Plastic modification is a method of improving the quality of plastics by adding additives, fillers, etc. to alter their properties. Meanwhile, plastic modification is also the most effective way to reduce the cost of plastics. The elements of formula design in plastic modification mainly include material selection, compounding, dosage, and mixing method. The interaction between various elements can be either mutual assistance or mutual cancellation. Therefore, designing a high-performance, easy to process, and low-cost formula is not an easy task.

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.

PVC needs to add additives in processing in order to produce various products that meet people's needs, such as soft, hard, transparent, good electrical insulation, foaming, etc. When selecting the variety and dosage of additives, it is necessary to comprehensively consider various factors, such as physical and chemical properties, flowability, and formability, in order to ultimately establish an ideal formula.

Coupling is an important connecting device between the main motor of the extruder and the gearbox. Currently, nylon rod couplings and safety couplings are commonly used on the market. Nylon rod couplings have a simple mechanical structure and low cost, but the torque is not accurate. They rely entirely on the shear force of the torque greater than that of the nylon rod. When the nylon rod is cut off, it needs to be reattached.

The main components of automobile lights are composed of reflectors, lenses, casings, light sources, electronic circuits, and installation accessories. With the development trend of lightweight automobiles, the proportion of plastics in automobiles is getting higher and higher.

With the development of industries such as automobiles, machinery, electronics, and aerospace, the requirements for material properties are becoming increasingly high. Developing high-performance and multifunctional modified nylon (PA) special materials has become a major research and development topic.
