Processability and Trends in the Mechanical Properties of Low Density Polyethylene Parts Produced Using Increasing Levels of Commingled Recyclate as a Filler

摘要

As the plastics industry is increasingly confronted with environmental demands and regulations, the need for successful and reliable recycling programs is greater than ever. One of the keys to the success of these recycling programs and to the success of recycled resins is identifying feasible end uses for commingled recycled polymers. One possibility is for plastics manufacturers to specify commingled recycled resins, as a filler, in their products. This can provide savings for the manufacturer, while helping to promote plastics recycling. When specifying the level of commingled recycled resin to be used in a product, the designer must consider the net effect it will have on the proc-essability and the mechanical properties of the part. This study will examine and attempt to predict the net effect of increasing the level of commingled post-consumer and post-industrial recyclate, used as a filler, in the production of low-density polyethylene parts.
