What are the processing techniques for modified plastics?

　　The processing techniques for modified plastics mainly include the following methods:

　　Add the modified method

　　By adding small-molecule inorganic or organic materials (such as fillers, reinforcing fibers, flame retardants, etc.) to polymers, performance can be enhanced through a simple and cost-effective process, making it ideal for improving properties like strength, toughness, and flame resistance.

　　Blending Modification

　　Blending different polymers or fillers can enhance performance—for example, nylon alloying improves water absorption and dimensional stability by incorporating other high polymers, or polymer alloys can be created through dynamic vulcanization.

　　Chemical reaction modification

　　This includes chemical methods such as copolymerization and crosslinking—for example, ABS plastic, which enhances material performance by modifying polystyrene with the addition of acrylonitrile and butadiene.

　　Nanocomposite Modification

　　Introducing nanomaterials (such as carbon fibers and whiskers) into plastics significantly enhances thermal performance, mechanical properties, and barrier characteristics—while keeping costs comparable to those of conventional plastics.

　　Surface Modification

　　Directly improve plastic surface properties such as glossiness, anti-aging performance, and conductivity, or enhance the adhesion of coatings through surface treatments—ideal for optimizing electroplating processes.

　　Interpenetrating Network Modification and Reactive Extrusion Method

　　Achieve compatibilization or crosslinking reactions via a twin-screw extruder, resulting in an interpenetrating network structure, or carry out blending and crosslinking simultaneously in the molten state.
