The concept, classification and distinction of modified plastics and plastic raw materials.
(1) according to the characteristics of resin when heating and cooling, classification: 1. Thermosetting plastics, two, thermoplastics(2) according to the classification of plastic use: general plastics, engineering plastics, plastic raw materials
Modified plastics should, in principle, be made from the plastic raw materials produced by petrochemical plants. By adding plastic additives, they can enhance their hardness, fire resistance, high temperature or low temperature, weather resistance and ultraviolet resistance. Therefore, modified plastics are processed from plastic raw materials, which is the relationship between source and flow.
Classification: modified plastic products are mainly a variety of flame retardant resins, toughening resin, plastic alloy, functional masterbatch etc..
Concept: modified plastics, refers to the base of the general plastics and engineering plastics, after filling, blending and enhancement processing method of modification, improve the performance of flame retardant plastic products, strength, impact resistance, toughness.
