METHOD OF PRODUCING RIGID POLYURETHANE AND POLYISOCYANURATE FOAMS USING POLYETHYLENE TEREPHTHALATE WASTE STREAMS AS POLYOL EXTENDERS |
摘要 |
A polyethylene terephthalate waste stream comprising polyethylene terephthalate oligomers, monoethylene glycol and polyethylene glycols can be employed as a polyol extender in the production of rigid polyurethane and polyisocyanurate foams. The properties of such foams are comparable with those made without an extender or with the use of the more expensive commercially available extender. |
