  • 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.
