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.
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.
ABS
Type: ABS
Strength, Economical, Processability
ABS (Acrylonitrile-Butadiene-Styrene Copolymer) is a well-balanced engineering plastic with good mechanical properties, excellent impact resistance, and easy processability. These characteristics have led to its widespread application in fields such as consumer electronics, household appliances, automotive industry, and daily necessities.
PC
Type: PC
Impact Resistance, Processability
PC (polycarbonate, commonly known as bulletproof glue) is inherently pale yellow or colorless and transparent, featuring hardness, toughness and luster. It boasts prominent advantages: with a light transmittance of 90%, it not only has good mechanical strength but also excellent impact resistance, along with outstanding heat resistance and weatherability.
PMMA (Acrylic)
Type: PMMA (Acrylic)
Impact Resistance, High Transparency, Weather Resistance
Acrylic (also known as polymethyl methacrylate, PMMA) boasts not only excellent optical performance but also outstanding UV resistance. With a light transmittance of up to 92%—comparable to glass—it has become a popular material in scenarios ranging from neon signs in shopping malls and display case panels in museums to precision optical lenses and stage light covers.
