Injection Molding Materials Classification

Injection molding materials are usually divided into the following 5 categories according to the scientific classification system:
Commodity Thermoplastics (PP, PE, PS): Cost-effective solutions for high-volume applications
Engineering Plastics (ABS, PC, Nylon, POM): Enhanced mechanical/thermal properties
High-Performance Polymers (PEEK, PPS, PEI): Extreme temperature/chemical resistance
Thermosetting Polymers(Epoxy, Silicone): - Irreversible curing for electrical insulation
Modified Compounds: Custom blends with additives (e.g. glass-filled nylon)
Future innovation directions include modified plastics that can be more customized for different performance needs. All injection molding materials are classified based on characteristics like durability, heat resistance, flexibility, and eco-friendly options.
