PCTG (polycyclohexylenedimethylene terephthalate glycol-modified copolymer) is the premium BPA-free clear polymer for injection blow molding applications requiring water-clear transparency, chemical resistance to cosmetic formulations and food contact compliance. Korea Ever-Power ZQ40 and ZQ60 IBM machines produce PCTG containers from 10ml through 500ml for cosmetic, personal care, food and pharmaceutical applications where clarity, chemical resistance and BPA-free compliance are simultaneously required.<\/p>\n

PCTG IBM wall haze below 1% at 0.5-0.8mm body wall \u2014 comparable to glass clarity and superior to GPPS IBM at equivalent wall thickness due to PCTG\u2019s amorphous copolyester structure<\/p>\n<\/div>\n

PCTG IBM barrel temperature range on Korea Ever-Power ZQ40\/ZQ60 \u2014 significantly higher than PP (210-240\u00b0C) but lower than PPSU (340-370\u00b0C), requiring standard ZQ40\/ZQ60 barrel configuration without special high-temperature upgrade<\/p>\n<\/div>\n

PCTG is hygroscopic and MUST be dried to below 0.02% moisture before IBM processing. Insufficient drying produces hydrolytic degradation and bubble\/haze defects in PCTG IBM wall. Minimum 4-hour drying at 80-90\u00b0C in dehumidifying hopper dryer<\/p>\n<\/div>\n

CHEMICAL RESISTANCE<\/p>\n

Superior to PS\/PP<\/p>\n

PCTG IBM resists alcohols up to 70%, aromatic fragrance components, esters, and cosmetic surfactants that cause haze or ESCR failure in PS or PP IBM \u2014 making PCTG IBM the preferred material for cosmetic formulations with alcohol or essential oil content<\/p>\n<\/div>\n<\/div>\n<\/div>\n
