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.
PC+ABS
Type: PC+ABS
Impact Resistance, Strength
PC+ABS is a blend-modified material that combines the advantages of both materials. It not only inherits the high impact resistance of PC but also the material strength of ABS, while improving its heat resistance. It is often used in electronic product casings, automotive interiors, consumer products, and more.
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.
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.
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.
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.
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.
