PURPOSE: To prevent microorganisms such as bacteria, yeasts fungi, etc., from growing on the surface and interior of plastic components of a washing machine by dispersedly mixing 2-(4-thiazolyl)-benzimidazole as an antimicrobial substance for suppressing the growth of microorganisms in the material for the plastic components of the washing machine.
CONSTITUTION: Polypropylene 22 as a main material for washing machine components contains 10% of talc 23 for improving the rigidity of the components. To the total amount of the talc 23 and the polypropylene resin 22 is added 0.1-2.0weight% of 2-(4-thiazolyl)-benzimidazole of storing antimicrobial property and excellent heat resistance. As inorganic substance for increasing volume, reinforcement, etc., granular inorganic substance such as calcium carbonate, barium sulfate, and mica, or further fibrous inorganic material such as glass fibers may be mixed by any amount according to requirement.
