Plastic alloy is to use physical blending or chemical grafting method for high performance, functional and specialty of new materials, including generally plastic alloy and engineering plastics alloy. General plastic alloy, such as PVC (polyvinyl chloride), PE (polyethylene), PP (polypropylene), PS (polystyrene) alloy, these still have wide use-value, but because of its production technology is widely mastered, in foreign countries, the company supplies more varieties is high value engineering plastics alloy. Engineering plastics alloy blend of general engineering plastics (resin), mainly including to PC, PBT, PA, POM (POM), PPO, such as PTFE (polytetrafluoroethylene) engineering plastics as the main body of the blend system, as well as ABS resin modified materials. The comprehensive performance of PC/ABS plastic is good, but its chemical resistance is poor and vulnerable to more powerful chemical solvent corrosion cracking and other defects caused by products. The material has been widely used in GM's rear license plate, Volkswagen & LAVIDA car’s rear door’s decoration, and etc.
Main plastic alloy materials PC-ABS Plastic Alloy Materials ABS engineering plastics aka PC + ABS (engineering plastic alloy),this material has both PC resin’s excellent heat resistance, weather resistance, impact resistance and dimensional stability, and also has ABS resin’s excellent fluidity. So it is used in thin –walled and complex shape products, can maintain its excellent performance, and maintain the plastic and a kind of ester composition of the material. It can be widely used in automotive parts, business machines, telecommunications equipment, Household appliances and lighting equipment. PC-PBT Plastic Alloy Material PC-PBT is a blend of PC and PBT.PC has the advantage of tough and strength ender room temperature, but in the case of high temperature, heat deformation is serious. The disadvantage is that the stress is cracked under force and the viscosity is large. The advantage of PBT is that its rigidity is not affected by temperature and the deformation is small. The blended material PC-PBT retains the advantages of PC and PBT. PC-PBT has high surface hardness, high rigidity and toughness, but also has high resistance to high temperature, and also has high resistance to stress cracking; It can be widely used in car bumpers, car handles, electronic components and so on. PC –PMMA Plastic alloy Material PC-PMMA is a blend of PC and PMMA. Both PC and PMMA is layered, but not compatible with each other. Its alloy (PC –PMMA) is a multi-layer structure, due to the different refractive index of them, the incident light in the reflection will produce light interference, so the alloy opaque, but with pearl color, can be made to pearl-like products. PC –PMMA plastic is transparent, tasteless, non-toxic, and can issue pearl like light, it is high-grade food packaging material.
