Modified plastic products are currently widely used in home appliances, automobiles, communications, medical, electronic and electrical, rail transit, precision instruments, home building materials, security, aerospace, military and other fields. From 2010 to 2019, my country's modified plastics also achieved a rapid increase, from an annual output of 7.05 million tons in 2010 to about 19.55 million tons in 2019; the modification rate increased from 16.2% in 2010 to 2019 Of 20.4%.

Plastics are currently widely used in various production activities in human society, with a wide range of downstream applications due to their light weight, high strength, insulation, light transmission, and wear resistance. 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. Modified plastic products refer to the addition of suitable additives, fillers or other polymer components on the basis of general plastics, engineering plastics or special engineering plastics, which are processed and modified 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, modified plastic products are better than plastics in terms of flame retardancy, strength, impact resistance, and aging resistance.
