Plastics are macromolecular compounds (macromolecules) polymerized by addition polymerization or polycondensation with monomers as raw materials. They have moderate deformation resistance, intermediate between fibers and rubber, and are composed of synthetic resins, fillers, plasticizers, and stable Additives, lubricants, colorants and other additives.
The main component of plastic is resin. Resin is a polymer compound that has not been mixed with various additives.
Household plastics are mainly general plastics, including PP, PVC, PS, ABS, HIPS, GPPS, etc.
The main characteristics of plastics for home appliances: better mechanical properties, thermal properties, aging resistance; flame retardant properties, electrical insulation properties; better processing properties, dimensional stability; low price.
Among household appliances, televisions, washing machines, refrigerators, and air conditioners have a large demand for plastic raw materials, especially for washing machines and refrigerators, each of which is 30% -40% or more. The plastic content of TV sets is 23% -25%, and the air conditioner is 11%. In the future, the pace of “replacing steel with plastic” in the home appliance industry will accelerate, and its demand for plastics will be even greater.
PP and PS account for an important proportion of the four household electrical plastics, of which PS accounts for 84.5% of the amount of plastic used in the production of televisions, and PP accounts for 76.5% of the amount of plastic used in the manufacture of washing machines, both of which are important and The main proportion, in addition, ABS, PVC also accounted for an important proportion in home appliance plastics.
