Abstract

PURPOSE: To obtain at low cost plastics having excellent toughness, heat resistance, etc., by blending gypsum with plastics in the production of the plastics.
CONSTITUTION: Gypsum in the form of powder etc. and in a desired ratio is blended in any desired stage of the process for the production of plastics to obtain the desired plastics. For example, when 10W15wt% gypsum is incorporated into materials for the production of the plastics, there can be obtd. molded articles having somewhat low hardness. When 60W70wt% gypsum is incorporated into the plastics, there can be obtd. molded articles having high hardness. The amount of gypsum to be blended is determined according to the purpose and use. The molded articles obtd. therefrom have excellent mechanical strength etc. and are suitable for automobile body, panel, etc.
