。Conventional technology and its challenges In recent years, as products have become more sophisticated, thermoplastic resins with excellent sliding properties, i.e., thermoplastic resins with low wear and low coefficient of friction, have been used in a wide range of fields such as various electronic device parts, sports goods, and leisure goods. There is an increasing demand for plastic resins. Therefore, many attempts have been made to improve the sliding properties of thermoplastic resins in order to cope with the current situation. As a method for improving the sliding properties of thermoplastic resin, there is, for example, a method of mixing inorganic particles into thermoplastic resin. However, when this method is used, although the amount of wear of the obtained molded product itself is reduced, the amount of wear of the other material with which it comes into contact increases,
In addition, the fluidity of the resin during molding deteriorates, resulting in poor processability, making it difficult to manufacture precision molded products such as thin-walled molded products.

This causes the molded product to become distorted or deformed. Furthermore, the surface smoothness of the shaped product cannot be obtained.
