Dow DOWLEX™ IP-41 High Density Polyethylene
Categories:	Polymer; Thermoplastic; Polyethylene (PE); High Density (HDPE); High Density Polyethylene (HDPE), Injection Molded
Material Notes:	DOWLEX® IP-41 resin is an improved processing high density polyethylene resin designed to offer excellent processability and rigidity required for food containers, overcaps, and other general purpose applications. DOWLEX IP-41 resin balances peak molecular weight with a proprietary, optimized molecular weight distribution and a slightly higher density for excellent rigidity. This resin has demonstrated excellent processability over a wide range of molding conditions. This material complies with FDA regulation 21 CFR 177.1520 (c) 3.2 (a) for food contact applications.
