There are many common plastic modification technologies, mainly reinforcement technologies, including fiber reinforcement, self-reinforcement, molecular reinforcement; toughening technology; filling modification; blending and plastic alloy technology; flame retardant technology; nanocomposite technology; reaction graft modification; aging resistance; functional modification, including electrical conductivity, antistatic, thermal conductivity and luminescence, etc.; thermoplastic elastomer technology.

Floating fiber is also known as exposed fiber, that is, glass fiber exposed in the product surface, relatively rough.

The modified plastics are plastic products with specific properties processed or modified by physical, chemical or mechanical methods to improve the properties of the resins in terms of flame retardancy, aging resistance, mechanical properties and electrical, magnetic, optical and thermal properties

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".
