Japan Polypropylene (PP) will maintain a 70% production rate at all its facilities until the end of February due to weak demand. “We have been running our plants at this rate since early December due to poor demand,” the source said. As one of the largest PP producers in Japan, Japan PP’s facilities at several locations have a combined capacity of about 1.08m tonnes. The start-up of its new 300,000 tonne/year PP plant had been postponed due to weak demand. Mitsubishi Chemicals holds a 65% stake in Japan Polypropylene, while Chisso Petrochemical holds the remaining 35% stake.
