CERTENE HI-752 Muehlstein Polyethylene, High Density

Product Description

HI-752 is a certified prime copolymer designed for INJECTION MOLDING applications requiring good balance of mechanical properties. HI-752 features easy processability, good stiffness, good impact strength, high warpage resistance and excellent dimensional stability. HI-752 is especially suitable for pails, waste bins, bottle and fish crates, tote bins, fruit and vegetable trays, and handling materials where resistance to low temperature impact and toughness is required. HI-752 is not UV stabilized. Recommended processing temperature is 210 to 250°C. with mold @ 20 to 40°C.. HI-752 complies with FDA regulation 21CFR 177.1520 (c) 3.1 (a) + 3.2 (a) and with most international regulations concerning the use of Polyethylene in contact with food articles.
