pom plastic materials, plastic Jichang (certified), Daling Shan plastic pom provided by Dongguan Chang Ping Jichang plastic materials. Dongguan Changping Jichang plastic materials (jichang668.1688.com/) is specialized in the "plastic materials, fire-retardant plastics, engineering plastics, POM, PC, PA66, PA6" business, the company adhering to the "honesty, hard service "concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Mr. Zhou. POM processing conditions (for reference only, the actual situation according to specific grades may be): (1) drying: If pom plastic raw material storage, without drying in a dry environment, dry conditions 80-90 ℃, 2 hours. (2) POM melting point is 190-230 degrees Dongguan pom plastic materials, acetal copolymer melting point is 190-210 degrees. (3) Mold temperature: 80-105 degrees, in order to reduce mold shrinkage pom plastic, can choose higher mold temperature. (4) Injection pressure: 700-1200bar. (5) Injection speed: medium or high injection speeds. POM characteristics and uses: (1) low coefficient of friction and good geometric stability, particularly suitable for the production of gears and bearings; (2) good high temperature performance for pipe fittings (pipe valve, pump housing), lawn equipment; (3) tough, flexible, low-temperature creep resistance; (4) having a high crystallinity resulting in a relatively high shrinkage (1.2-3.0%); (5) melting point significantly, once they reach the melting point, melt viscosity decline rapidly.
