Detailed Product Description: | Since PA PA retardant added flame retardants, flame retardant most easily decomposed at high temperature, the release of the acidic substance having a corrosive effect on the metal plate nylon PTFE plate temperature, and therefore, the plasticizing component (screw, a plastic head, apron, over pad ring, flange, etc.) need to hard chrome plating. Technological aspects, try to control the barrel temperature is not too high, not too fast injection speed, in order to avoid high temperature plastic material decomposition products cause discoloration and mechanical performance. Nylon Performance: chemical and physical properties of PA6 and PA66 are very similar, however, the low melting point, and the process temperature range is very wide. Its impact resistance and solvent resistance better than PA66, but also more moisture. PA6 shrinkage between 1% to 1.5%. Join fiberglass shrinkage can be reduced to 0.3% to 0.5% (but perpendicular to the flow direction and even slightly higher). PA6 due to have a good mechanical strength, stiffness and wear characteristics of POM rods board tetrafluoroethylene film is widely used in structural components and manufacturing bearings. PA6 is easy to absorb moisture PTFE, so the drying process with particular attention. Recommended drying at 90 ℃ 12 hours. The melt temperature was 230-280 ℃, for enhancing varieties 250-280 ℃. Mold temperature: 80-90 ℃. If the wall thickness is greater than 3mm, recommend the use of low temperature 20-40 ℃ Mold. For glass fiber reinforced materials mold temperature should be greater than 80 ℃. pp pp plates stick PTFE plate corrosion, Tianjin Third, PTFE provided by Three Plastic Co., Ltd. of Tianjin. Three Plastic Co., Ltd. Tianjin (www.tjzssj.com) strong, credible, in Tianjin plastic plate (sheet, section), bar industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Tianjin into the brilliant three and you work for a better future! |
