A resin composition for sliding member according to the present invention contains 40 to 80 mass% of a polyphenylene sulfide resin and as an additive, 15 to 40 mass% of a polytetrafluoroethylene resin, 2 to 20 mass% of an ultra-high molecular weight polyethylene resin, 0.1 to 5 mass% of a modified polyolefin resin, and 0.5 to 5 mass% of an amorphous polymer.

The present invention provides: a graphite sheet polyimide film, which is derived from a first precursor composition comprising a first polyamic acid and comprises a sublimable inorganic filler and a spherical polyimide-based filler; a manufacturing method therefor; and a graphite sheet manufactured using the same.

The present invention relates to a resin composition containing a polyvinyl chloride resin and an acrylic resin and a board for interior materials manufactured using the same. More specifically, the present invention relates to a resin composition having excellent heat resistance due to a high glass transition temperature, having high flexibility even with a low plasticizer content, and having excellent processability due to such properties, as compared with the case wherein a polyvinyl chloride resin is used alone, and to a board for interior materials manufactured using the resin composition. According to the present invention, the resin composition may be applied to both a calendering method and an extrusion method due to excellent processability thereof.
