Polyimide resin
    Thermoplastic polyimide resin

    BH-TPI-w01

    BH-TPI-w01 polyimide resin material is a polymer with a chain-like structure featuring imine and aromatic rings in its main chain. It is easy to process and shape, and its thickness can be flexibly adjusted according to specific needs, meeting various application requirements. During processing, no chemical crosslinking occurs, and it can be melted and processed again after damage. It possesses self-extinguishing and flame-retardant properties, with a high oxygen index, and does not release toxic gases after combustion. It exhibits good radiation resistance, maintaining structural stability under high temperature, high vacuum, and radiation exposure conditions. With excellent insulation properties, it retains superior electrical characteristics even in high-temperature environments, making it suitable for use in high-voltage motors.
