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.
TPU
Type: TPU
Impact Resistance, Wear Resistant, Chemical Resistant, Aging Resistance
TPU (Thermoplastic Polyurethane), commonly known as urethane rubber, is a thermoplastic elastomer. It features excellent elasticity, abrasion resistance, and chemical corrosion resistance, and is widely used in applications such as mobile phone cases (soft shells), sports shoe soles, and medical catheters.
CPVC
Type: CPVC
Temperature Resistant, Chemical Resistant, Flame Retardancy
CPVC (Chlorinated Polyvinyl Chloride) is a thermoplastic plastic obtained by chlorination modification of polyvinyl chloride (PVC). Such structural changes enable it to far outperform ordinary PVC in terms of heat resistance, mechanical properties, and chemical resistance, making it an ideal material for high-temperature and corrosive environments.
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.
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.
TPU
Type: TPU
Impact Resistance, Wear Resistance, Chemical Resistant, Aging Resistance
TPU (Thermoplastic Polyurethane), commonly known as urethane rubber, is a thermoplastic elastomer. It features excellent elasticity, abrasion resistance, and chemical corrosion resistance, and is widely used in applications such as mobile phone cases (soft shells), sports shoe soles, and medical catheters.
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.
