Methods, systems, and apparatuses of manufacturing an automotive interior trim panel are provided. The method includes providing a mold having a negative side and a positive side, heating the mold using a first heater and a second heater, coupling the mold to a first powder box containing a first polymeric powder, molding a first polymer layer on the first side of the mold by rotating the mold, coupling the mold to a second powder box containing a second polymeric powder, and molding a second polymer layer on the first polymer layer by rotating the mold. The method further includes heating the second polymer layer during which the second polymer layer expands, compressing the thickness of the second polymer layer, cooling the positive side of the mold to reduce the temperature of the first polymer layer and the second polymer layer, and removing the part from the mold.

Provided is a vinyl chloride resin composition that is capable of forming a vinyl chloride resin molded product having suppressed gloss change. The vinyl chloride resin composition contains a vinyl chloride resin, a plasticizer, and a hindered amine light stabilizer having a molecular weight of not less than 550 and not more than 1,500. The content of the plasticizer is 75 parts by mass or more relative to 100 parts by mass of the vinyl chloride resin. The vinyl chloride resin composition is preferably used in powder molding.

A method of making a powder polyvinyl chloride-based composition comprises blending an emulsion of a polyvinyl chloride resin and a flexible acrylic resin to form a polyvinyl chloride resin/flexible acrylic resin blend. The polyvinyl chloride/flexible acrylic resin blend is isolated to form the powder polyvinyl chloride-based composition. A powder polyvinyl chloride-based composition, a polyvinyl chloride formulation, an article formed from the powder polyvinyl chloride-based composition, and a method for forming the article are also disclosed.
