Today, modified plastics are an emerging industry and are in a period of rapid development. Especially in the automotive and home appliances, it has broad prospects for development.
Modified plastic for vehicles
At present, major auto companies are looking for ways to reduce fuel consumption, including body weight loss. By increasing the amount of modified plastics for automobiles, the weight of the vehicle body is reduced, thereby realizing light weight of the automobile. Generally, the specific gravity of plastic is 0.9-1.6, and the specific gravity of glass fiber reinforced composite is less than 2.0, while brass is 8.4, A3 steel is 7.6, and aluminum is 2.7. Therefore, although it is not as strong as carbon fiber or metal material in terms of strength, the weight reduction effect of plastic is the best in terms of specific gravity, and it can be said to be the material of choice for lightweight vehicles.
PP blended modified plastic is blended with PP base material by filler, crosslinker, coupling agent, compatibilizer, reinforcing agent, anti-aging agent, and melt flow rate modifier to modify PP. Greatly improve its performance. It is a traditional process for producing PP bumper special materials by blending various synthetic rubbers and PP to improve the low temperature toughness of PP. Most of the bumper materials are toughened with EPDM. At present, SBS, SEBS (styrene-ethylene-butadiene-styrene block copolymer) and other toughening, or EPDM and SEBS, EPDM and PE are used together. China's bumper special materials are mainly modified by PP/EPDM blending.
Modified plastics for household appliances
The home appliance industry is one of the most important industries in the modified plastics industry. The application of modified materials in the field of home appliances is more and more extensive. In the future, there are six major trends in the modification of home appliance plastics: lightweight, more attractive colors, and continuous improvement of safety indicators. Low cost, energy saving, low carbon and healthy.
The demand for modified plastics in home appliances is constantly changing, requiring modified plastics manufacturers to continuously improve their formulations according to customer needs. Modified plastics can be used to make exterior parts, casings, and blades for home appliances. In addition to large appliances such as TVs, refrigerators, and washing machines, the demand for modified plastics in small household appliances such as microwave ovens, rice cookers, soya-bean milk makers, and electric ovens is also growing.
