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.
HIPS
Type: HIPS
Impact Resistance, Economical, Electrical Insulation
High Impact Polystyrene (HIPS) is a low-cost and easily processable plastic material. It is often used in the manufacturing of low-strength structural components in scenarios where comprehensive requirements for a material’s impact resistance, processability, and cost are required. Additionally, with its excellent dimensional stability and ease of being painted and bonded, it has become an ideal material for prototyping.
HDPE
Type: HDPE
Corrosion Resistance, Strength, Electrical Insulation
High-Density Polyethylene (HDPE) is a lightweight, chemically resistant, and high-strength material. It is flexible and tough, commonly used in applications such as food packaging (e.g., food containers), agricultural films, daily necessities (e.g., storage boxes), and water tanks.
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.
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.
