Polyimide resin
    RTM polyimide resin

    BH-RTM

    BH-RTM polyimide resin material is a polymer with a chain structure featuring imine and aromatic rings in its main chain. It exhibits a very low melt viscosity, with a viscosity of ≤1.0 Pa·s during melting and a maintenance time of ≥2 hours. The curing process is straightforward. When compounded with other materials, it demonstrates excellent rheological properties and high stability during the heating and curing process, without releasing small molecules that could damage the internal structure of the material. Its long-term use temperature can exceed 300°C, and its short-term use temperature can exceed 500°C.
