NATURAL SOLVENT FOR REDUCING VOLUME OF FOAMED POLYSTYRENE, AND METHOD FOR VOLUME-REDUCING TREATMENT OF FOAMED POLYSTYRENE USING THE SAME

摘要

PPROBLEM TO BE SOLVED: To provide a method by which a foamed polystyrene is inexpensively, safely and rapidly dissolved, and subjected to volume reduction. PSOLUTION: A natural solvent for reducing the volume of the foamed polystyrene is characterized by comprising at least one kind of compound selected from among geranyl acetate, terpinolene, -terpinene, -terpinene, -phellandrene, p-cymene, bornyl acetate, 1,8-cineol, -pinene, terpinen-4-ol, iso-thymol, citral, citronellal, terpinyl acetate, and citronellyl acetate. The method for a volume-reducing treatment of the polystyrene using the natural solvent is provided. PCOPYRIGHT: (C)2009,JPO&INPIT
