Dow DOWLEX™ IP-22 High Density Polyethylene
Categories:	Polymer; Thermoplastic; Polyethylene (PE); High Density (HDPE); High Density Polyethylene (HDPE), Impact Grade
Material Notes:	DOWLEX® IP-22 resin is an improved processing high density polyethylene resin designed for excellent flow, high impact, and moderate stiffness. DOWLEX IP-22 resin balances peak molecular weight with a proprietary, optimized molecular weight distribution and a slightly lower density for impact and integrity. Typical applications are housewares, toys and general purpose applications. This material complies with FDA regulation 21 CFR 177.1520 c 3.1 for food contact applications. The regulation should be consulted for complete details. Data provided by Dow Chemical.
