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.

  • CNC machined TPU automotive seals and gaskets

    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 injection molding plastic material — high-performance, chemical-resistant, and durable plastic for precision-molded components.

    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.

  • PTFE injection molding plastic material — high-performance, chemical-resistant, heat-resistant, and durable plastic for precision-molded components.

    PTFE

    Type: PTFE

    Temperature Resistance, Corrosion Resistance, low friction Coefficient, Aging Resistance

    Polytetrafluoroethylene (PTFE), commonly known as Teflon, is a high-performance fluoropolymer. It is frequently used in mechanical components requiring reduced friction and wear—such as bearings, gears, and piston rings—due to its non-stick properties, low friction characteristics, and self-lubricating capabilities. PTFE also exhibits excellent electrical insulation properties, making it highly suitable for applications like high-frequency cables, high-voltage insulators, and electronic components.

    Additionally, PTFE maintains stable performance during long-term use across an extreme temperature range from -200°C (ultra-low temperature) to 260°C (high temperature), enabling its use in harsh environments such as aerospace systems, deep-sea equipment, and high-temperature industrial apparatus.

  • LDPE plastic material with excellent flexibility and chemical resistance for injection molding and packaging applications.

    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 injection molding plastic material — high-density, durable, and chemical-resistant plastic for precision-molded components.

    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.

  • PET injection molding plastic material — high-strength, chemical-resistant polymer for precision-molded components and industrial applications.

    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.
