Polyphenylene sulfide (PPS) is a high rigid crystalline resin engineering plastic with stable structure, which has the advantages of high temperature resistance, non toxicity, flame retardancy, chemical corrosion resistance, good insulation performance and so on. It can be used in rigid and durable mechanical products; On electrical products requiring heat and flame resistance; It can also be used in chemical devices requiring corrosion resistance. Especially under the conditions of high temperature, high humidity and high frequency, it still has excellent electrical properties. The electronic label encapsulated by PPS engineering plastic has many advantages, such as high temperature resistance, flame retardancy, chemical corrosion resistance, high rigidity and wear resistance, and can be used in the harsh environment of high temperature, high humidity, wear resistance and corrosion resistance, such as laundry, automobile engine maintenance identification, chemical raw material tracking and many other applications of electronic labels.
