15mm Round PPS NTAG 213 NFC Tag is made of PPS and heat-resistant vinyl material with Ntag213 nfc chips .A carrier capable of withstanding high temperatures, acid-base corrosion, and other special requirements. It is made of high-rigidity crystalline resin engineering plastic, featuring stable structure, heat resistance, non-toxicity, flame retardancy, chemical corrosion resistance, and good insulation properties. It can be used in rigid and durable mechanical products, as well as electrical products requiring heat and flame resistance, and in chemical equipment requiring corrosion resistance. It has extensive applications in material sorting, workpiece identification, and glass product tracking and management. Normal working temperature is﹣20℃~65℃, for special working environment such as -10℃~100℃ (14°F /212°F ) can work each 30mins and 200 cycles , high temperature 100℃(212°F) can store over 1000 hours  , -10℃~140℃ (14°F/284°F) can work each 30mins and 100 cycles .storing under 140℃(284°F) will 200 hours .They all follow IP67 level and water proof ,dust proof ,moisture proof ,etc.Another rfid frequency chips are available .
