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.
LDPE
Type: LDPE
Corrosion Resistance, Toughness, Electrical Insulation
Low-Density Polyethylene (LDPE) is lighter than water, soft and tough, with excellent acid and alkali resistance as well as electrical insulation properties. It is widely used in fields such as packaging, agriculture, electronics, and daily necessities.
PVC
Type: PVC
Economical, Weather Resistance, Flame Retardancy
Polyvinyl chloride (PVC) is a widely used thermoplastic polymer material characterized by excellent mechanical properties, outstanding corrosion resistance, and superior electrical insulation performance. By incorporating various additives, it can be tailored to meet customized requirements. Owing to its unique combination of properties, PVC finds extensive applications in fields such as construction, industry, packaging, and healthcare.
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.
PEEK
Type: PEEK
Impact Resistance, Chemical Resistant, Food Grade, High Temp, Sterilizable
PEEK (Polyetheretherketone) is a top-performing thermoplastic engineering plastic, featuring excellent high-temperature resistance, robust mechanical properties, versatile corrosion resistance, top-tier biocompatibility, exceptional dimensional stability, and outstanding electrical insulation and radiation resistance. It is widely used in high-end fields such as aerospace, high-end medical care, and electronic semiconductors.
POM (Delrin)
Type: POM (Delrin)
Impact Resistance, Chemical Resistant
Polyoxymethylene (POM) is a premium high-performance engineering plastic. Known for its metal-like mechanical strength, it offers exceptional hardness, rigidity, impact and fatigue resistance, as well as outstanding wear resistance and self-lubrication. POM also provides excellent dimensional stability, strong chemical resistance, and ease of processing. With this unique combination of properties, it has become a preferred material across industries such as machinery, automotive, electronics, and medical devices—making it an ideal replacement for metal in manufacturing high-precision, wear-resistant components.
