Polyimide masterbatch products are used for injection molding. The performance reaches the level of similar products in Japan, which is higher than that of similar products in the United States. Due to military use, the US Congress has adopted a strategy of banning the sale of high-end thermoplastic polyimide materials to China, and only low-end products can be sold to China.
According to different product needs, there are two types of polyimide solution products developed, which are: Thermoplastic BLS-120 (low viscosity type) Thermosetting BLG-120 (high temperature type)
Polyimide profiles are made of thermoplastic/thermosetting powder materials through high temperature and high pressure processing. Dimensions and specifications can be customized. The material is mainly used in aviation, aerospace and rocket parts, heat insulation, seals, petrochemical, precision instruments and other fields.
The product is a truly fully soluble polyimide (PI) without the precursor - polyamic acid. The glass transition temperature (Tg) of the product is 320-330 °C, the temperature of thermal weight loss is about 525 °C, the intrinsic viscosity is 0.5-0.7dl/g (in NMP, 30 °C test), the product is 100% imidized, pure solid powder. At room temperature, it is soluble in common solvents. The dissolved concentration can reach more than 20%.
It is not easy to overflow during the molding process, which greatly improves the molding efficiency and yield of the molded products. The PI powder has uniform fineness and an average particle size of 800 meshes. The molded products have high transparency and light color. 20 products. This product has high temperature resistance, wear resistance, self-lubrication, high mechanical strength, radiation resistance, and good dimensional stability at high temperature.
BPG-100 is suitable for reinforcing materials, such as reinforced polytetrafluoroethylene, which can effectively improve temperature resistance, friction resistance, and dimensional stability (creep resistance).
