What is Recycling PET into Polyurethane Foam about?
The document discusses the chemical recycling of PET plastic to produce polyurethane foam. PET plastic is broken down using diethylene glycol and a manganese catalyst through a process called transesterification. This degrades the PET polymer chains. The degraded PET is then mixed with castor oil and toluene diisocyanate to produce a polyurethane pre-polymer. Blowing agents react to produce carbon dioxide gas, causing the pre-polymer to foam up into polyurethane foam. The castor oil improves the quality and
