Insulation Blankets on Polyolefin Plastics Processing Equipment – Cost and Analysis of Use (PPT)

摘要

Injection, extrusion and processing of polyolefin resins into products create cost in plants that may be modified by the use of insulation jackets on heated equipment components. Polyolefin materials are the most commonly used materials in large tonnage processing machines, and reducing the cost of energy and safety in processing can significantly impact profit and loss as well as eliminate many processing variables. Examining the use of removable insulation jackets on heated barrels, melt pipes, dies, and more, noting the effects on energy use, safety, ambient temperature, heater band life, wiring and overall operations yields several compelling factors and highlights criteria for use. Case studies include the estimated cost and ROI for operating with blankets versus without as well as estimated payback using power consumption curves and costing analysis. The use of blankets may be part of an overall energy and safety savings plan for the plant, and the straightforward approach yields both tangible and intangible benefits.
