Detailed

Halogen-free plastic and the difference between the general plastic, halogen refers to fluorine, chlorine, bromine, iodine, astatine and other halogen elements, halogen-free plastic does not contain the above elements (or content less than the specified value); due to the production requirements To meet the environmental requirements of halogen-free, in the molding of materials through high-temperature plasticization will be released, the decomposition of residual species of toxic and hazardous substances, but at the same time will have a very serious corrosion and wear, Will be depleted. The screw screw barrel can be used as the whole of the whole hardening, spraying the whole screw alloy, the cylinder bore (with high wear resistance, high corrosion resistance, high temperature and high pressure) Cast double alloy. Adhesive strength: 10000psi or more. Surface finish: screw surface is less than 0.04um. Surface hardness: HRC62-70 degrees. FR52G30NH BK337 high temperature halogen-free flame retardant nylon and so on. For halogen-free environmentally friendly products such as: electronic components, electrical connectors, household appliances, computer plugs, auto parts and so on.
