Polycarbonate Resin


Polycarbonate (abbreviated as PC) refers to a non-crystalline thermoplastic high molecular polymer containing a carbonate group (-COO-) in a molecular chain. It is a thermoplastic engineering plastic with excellent comprehensive performance. Its excellent performance in mechanical, optical and thermal properties makes it have three characteristics of high impact resistance, high transparency and high heat resistance. It is a durable engineering plastic.


(1) The product has four comprehensive characteristics of transparency, toughness, heat resistance and flame retardancy.

(2)Wide temperature range, stable performance over the temperature range of-100 ° C- 129° C

(3) High heat reflection temperature

(4) Low molding shrinkage and good dimensional stability

(5) Excellent electrical characteristics


Zhejiang Dexin Petrochemical PC plant adopts green environmental protection and international advanced non-phosgene processtechnology to produce PC products with a melt index of 5-35. The total planned capacity of PC is 520,000 tons/year, which is constructed in two phases. The design capacity of the first phase is 260,000 tons/yearr with the supporting upstream 240z000tons/year of bisphenol A (BPA), 640,000 tons/year of phenol/acetone. And a 200,000 tons/year dimethyl carbonate (DMC) unit.


As a thermoplastic engineering plastic with excellent comprehensive performance, ZPC polycarbonate products can bemainly used in optical lighting, electrical and electronic, automotive, construction, packaging, etc, and can be made into plastic alloys with other resins to meet specific needs.
