Injection Molding Materials
Choosing the right injection molding material can make or break your project. Our comprehensive guide helps you quickly compare options based on strength, flexibility, and heat resistance, so you can confidently select the ideal material for prototypes, production parts, or custom designs—ensuring high-quality results every time.
PEI
Type: PEI
Temperature Resistance, Strength, CorrosionResistant, Flame Retardancy, Electrical Insulation, Aging Resistance
PEI (polyetherimide) is a high-performance thermoplastic engineering plastic that combines excellent heat resistance, mechanical properties, and chemical stability, enabling it to be widely used in high-end industrial fields such as aerospace, electronics and electrical engineering, and medical equipment.
PP
Type: PP
Corrosion Resistant, Strength
Polypropylene (PP) is a well-balanced thermoplastic characterized by lightweight material, excellent chemical resistance, and good flexibility. Owing to these properties, it finds wide application in fields such as packaging, household appliances, automotive, daily necessities, and medical devices.
PET
Type: PET
Corrosion Resistance, Strength, High Transparency, Processability
PET (polyethylene terephthalate) is a common thermoplastic polyester with excellent mechanical properties and strong chemical resistance. It also offers glass-like transparency and luster, with a high light transmittance of about 88–92%, and is widely used in beverage bottles, food packaging, and engineering plastics.
