Polifil® RP-LDPE

Polifil RP-LDPE

Reprocessed Low Density Polyethylene

Polifil® RP-Low Density Polyethylene is a soft, tough material with good clarity and high chemical resistance. LDPE remains flexible and retains impact strength at very low temperatures. High melt flow (low viscosity) grades are injection molded into products such as containers and lids. Low melt flow (high viscosity) grades are used in blown films for bags and construction, extruded sheeting and pipe, and blow molded containers such as squeeze bottles. Linear Low Density (LLDPE) resins exhibit higher strength and stiffness than traditional LDPE resins for many of these same applications.

The property values listed in the PDF document(s) have been obtained using laboratory controlled test methods. They are offered without guarantee since conditions under which the product is used are beyond our control. Mold shrinkage is intended as a guide only, as specific shrinkage is affected by part design, mold design and molding conditions. Therefore, The Plastics Group disclaims any liability for loss or damage incurred in connection with the use of this product.
