The needs of the plastic board processing industry
The processing of plastic board due to its reasonable price and excellent product performance can improve certain physical properties of plastic products and become engineering plastics with special properties. With the rapid development of the plastics industry, the filled modified masterbatch is not only an additive material, which can reduce the cost of plastic products, but also improve certain physical properties of plastic products, such as reducing notch shrinkage, improving appearance and feel. And having market recognition has become an indispensable raw material in certain plastic products. Modified plastics is a new industry in the fastest growing plastics industry in recent years, and has become an important part of the plastics processing industry and the main material for plastic products.
Engineering plastics filled and modified masterbatch was put on the market in the early 1980s. The main raw material of the filling modified masterbatch is olefin resin, and non-metallic mineral powder is used as the filler (calcium carbonate, talc, kaolin, silica fume). The surface activator mainly includes aluminate coupling agent, titanate coupling agent, Silane coupling agent, etc. Plasticizers and other additives, mainly stearic acid, PE wax, paraffin wax, white oil, etc. Modified masterbatch is a new modified material developed on the basis of filler masterbatch. Modified masterbatch can significantly improve the physical properties of plastic products and improve the defects of certain materials, such as car bumpers and instrument decorations, using PP+ Talc powder can increase its impact strength and reduce shrinkage.
The plastic board processing reinforced masterbatch mainly uses inorganic materials (mica, glass fiber, etc.) to improve the mechanical properties of the product, and some resins or additives with special properties are added in the processing. , Such as adding antioxidants, heat stabilizers, flame retardants and other additives. For example, PEEK polyether ether ketone in special engineering plastics has the characteristics of high heat resistance, radiation resistance, corrosion resistance, fatigue resistance, high strength, wear resistance, and good electrical properties. It has been used in aerospace, defense and military industry, electronic information, It is widely used in medical and health, automobile manufacturing, household appliances, and other fields, and has become an indispensable key material. In particular, it can meet the needs of domestic aerospace, cutting-edge electronic equipment, national defense and military industry, nuclear energy and nuclear power industries.
