  • 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.

  • PEI polyetherimide engineering plastic pellets

    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.

  • 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.

  • Clear PMMA acrylic sheet for optical applications

    PMMA (Acrylic)

    Type: PMMA (Acrylic)

    Impact Resistance, High Transparency, Weather Resistance

    Acrylic (also known as polymethyl methacrylate, PMMA) boasts not only excellent optical performance but also outstanding UV resistance. With a light transmittance of up to 92%—comparable to glass—it has become a popular material in scenarios ranging from neon signs in shopping malls and display case panels in museums to precision optical lenses and stage light covers.

  • CNC machined TPU automotive seals and gaskets

    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 Acetal Plastic Material

    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.
