Some people believe that replacing metal with pps plastic will reduce product quality. In fact, the use of pps plastic instead of metal can improve product quality in many occasions. PPS material has the advantages of high temperature resistance, corrosion resistance and good mechanical properties. It can replace stainless steel, copper, aluminum, alloys and other metals, and is considered to be the best substitute for metals. In recent years, the scope of application of polyphenylene sulfide has been expanding, and it has been widely used in electronics, electrical, automotive, construction, machinery, new energy, transportation and other industries, and replacing steel with plastic has become an international trend.
Why can PPS plastic replace metal?
PPS plastic is a rising star. It not only retains the excellent characteristics of ordinary plastics, but also has higher temperature resistance and mechanical strength than ordinary plastics.
1. High performance
Modified PPS plastic is one of the best varieties of engineering plastics with high temperature resistance, and its thermal deformation temperature is generally above 260 °C. In addition, it also has the advantages of small molding shrinkage, low water absorption, excellent fire resistance, vibration fatigue resistance, strong arc resistance, etc., especially in high temperature and high humidity environments, it still has excellent electrical insulation, so it can be used in Many application areas replace metals as engineering materials.
2. Lightweight product
The specific gravity of ordinary pps plastic is about 1.34~2.0, which is only 1/9~1/4 of steel and about 1/2 of aluminum. This property of pps is especially important for mechanical equipment such as vehicles, boats, and airplanes that need to be reduced in weight.
3. High strength
For the same volume of material, the strength of pps is usually lower than that of metal, but because pps is much lighter than metal, when compared with the same weight of metal, pps is much stronger than ordinary metal. Among existing structural materials , it has the highest intensity.
4. Easy to process
PPS products are often formed at one time, while metal products generally have to go through several, a dozen, or even dozens of processes to complete. This feature of pps is very important to save working time and increase productivity. The machining of plastics is relatively simple. Plastic products are widely used in the automobile industry, which are mainly used to replace various non-ferrous metals and alloy materials, which not only improve the aesthetics of automobile modeling and the flexibility of planning, but also reduce the cost of parts processing, assembly and maintenance. It can also reduce the energy consumption of the car.
