There are many kinds of plastic products in our life. How can we distinguish that kind of plastic products better? Before we can tell, we must have a certain understanding of these plastics. We can determine what kind of plastic is environmentally friendly. Let's see what recycled engineering plastics are.
　　What types and uses of engineering plastics
　　Introduction of Engineering Plastics: polyphenylene ether
　　The consumption of polyphenylene ether has been very large, and has gradually replaced stainless steel to manufacture surgical medical equipment, and also involves the manufacture of gears, blower blades, pipes, valves and parts in some electronic and electrical industries.
　　Introduction of Engineering Plastics: polyphenylene sulfide
　　PPS is also a relatively high price in engineering plastics. It is often used in combination with other materials in the process of use, which has good heat resistance and can resist corrosion to a certain extent and has certain flame retardant performance.
　　Introduction of Engineering Plastics: polyamide
　　Polyamide is actually the nylon that people often say, and it is also the most popular one in engineering plastics. It has good mechanical properties, durability, corrosion resistance and heat resistance. Most importantly, it is also very convenient to process. It has been widely used in automobile, electronic and electrical industries.
　　Introduction of Engineering Plastics: Polycarbonate
　　Polycarbonate is characterized by metal strength and good ductility and toughness. It looks very like glass and has good light transmittance. Therefore, it is often used as lighting glass, lampshade, signal lamp, windshield, etc. it is one of the engineering plastics widely used at present.
　　Introduction of Engineering Plastics: polyformaldehyde
　　Polyformaldehyde is one of the most promising plastics in engineering plastics. Because of its hardness and strength as metal, it has gradually replaced some parts made of metal. It has been widely used in electronic, electrical, mechanical, instrument, daily light industry, automobile, building materials, agriculture and other industries. It is believed that its future development will be better.
