Polyphenylene sulfide microparticles
Polyphenylene sulfide microparticles have a linseed oil absorption amount of 40 to 1,000 mL/100 g and a number average particle diameter of 1 to 200 μm. The porous PPS microparticles have a large specific surface area and therefore promote fusion of particles when molded into various molded bodies by applying thermal energy, thus enabling formation or molding of a coating layer of particles at a lower temperature in a shorter time. The porous PPS microparticles have a porous shape and therefore enable scattering light in multiple directions and suppression of specific reflection of reflected light in a specific direction, thus making it possible to impart shading effect and matte effect when added to a medium.
