Temperature Control, Polyol & TDI Conditioning
In the polyurethane foam slab-stock process, constant, repeatable temperature of polyols and isocyanates at desired set points is of foundational importance. Precise temperature control and precise metering are of equal importance. The foam machine manager must have authority over as well as be responsible for the proper unloading, storage, conditioning, temperature control, metering and dispensing of chemicals (from tank car or tank truck to finished product). In this article I am attempting to assist that manager in doing a job well done.
