CPE can act as a compatibilizer between PVC and PE and can improve the properties of the blends. It is of great significance for the recycle and reuse of PVC and PE recycled plastics.
The main methods of modification are chemical modification, filling modification, strengthening modification, blending modification and nanocomposite modification.
In fact, any plastic raw material has at least a certain proportion of stabilizers when it leaves the factory to prevent it from degrading in storage, transportation and processing. Therefore, strictly speaking, "unmodified plastics" do not exist. In industry, basic resins produced by chemical plants are commonly called "unmodified plastics" or "pure resins".
Blending modification refers to the blending of other plastics, rubber, or thermoplastic elastomers with PP and filling them into larger crystal spheres in PP to improve the toughness and low temperature brittleness of PP.
PP is a common plastic raw material and one of the commonly used modified raw materials. The modification methods can be divided into four kinds: filling modification, strengthening and toughening modification, blending modification and functional modification.
Foamed PP has a broad development prospects.
Foamed plastics are widely used in various fields of daily life and industry due to their low density, good impact load absorption, good insulation, sound insulation and high specific strength.
The market for acrylic elastomers will grow from $648.2 million in 2017 to $983.9 million in 2022, with an annual composite growth rate of 8.7 percent, according to the latest forecast by Markets and Markets, a leading U.S. market research firm.
Special plastics for food packaging currently occupy the most important position in the field of food sales and packaging. It mainly includes PE, PP, PS, PET, PC, PVDC and so on.
Several formula of ps modification
The flame retardant modification of PA66 is mainly realized by two ways.
