Why are modified plastics widely used downstream?

As one of the three major polymer compounds, plastics are formed by the polymerization of various resins formed by the petrochemical industry through addition polymerization or condensation polymerization. They are currently widely used due to their light weight, high strength, insulation, light transmission, and wear resistance. In various production activities of human society.

With the characteristics of light weight, high strength, insulation, light transmission, and wear resistance, plastics are currently widely used in various production activities in human society and have a wide range of downstream applications. But the plastic itself has poor heat resistance, large thermal expansion coefficient, easy to burn; poor low temperature resistance, it becomes brittle at low temperature; it is prone to aging under the action of the atmosphere, sunlight, long-term pressure or certain media. The above shortcomings limit the plastic Further extensive applications.

Therefore, in some industries or usage scenarios that require high material performance, plastics need to be modified to meet the performance requirements. Plastic modification refers to the addition of suitable additives, fillers or other polymer components on the basis of general plastics, engineering plastics or special engineering plastics, and processing and modification by means of filling, toughening, reinforcement, etc., to improve the plastic material Some aspects of performance. The plastic processed by the above modification technology is called modified plastic. Generally speaking, the performance of modified plastics is better than plastics in terms of flame retardancy, strength, impact resistance, and aging resistance.
