  • PEI polyetherimide engineering plastic pellets

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

    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.

  • Low carbon steel CNC machining metal material — durable, high-precision metal for CNC machined components and industrial applications.

    Low Carbon Steel

    Economical, Machinability

    Low carbon steel (with carbon content not exceeding 0.25%) is one of the most commonly used types of steel in both industry and daily life, thanks to its excellent plasticity, weldability, and low cost. It is widely applied in components such as pistons, screws, and drive shafts. However, due to its limited strength, it usually requires post-treatment.
