Osterman & Co Osterlene® LD07520A LDPE
Categories:	Polymer; Thermoplastic; Polyethylene (PE); Low Density (LDPE)
Material Notes:	Product Description: LD07520 is designed for a wide variety of industrial film applications where high impact strength and excellent drawdown are needed. It exhibits uniformity, ease of processing and good tensile strength. Generally recommended extrusion conditions include a melt temperature range of 310-350°F (155-177°C) and a blow-up ratio range of 1.8-2.5:1. Drawdown to gauges below 1.0 mils (<25 microns) is possible at commercial rates when proper techniques are used. Availability: North America Additive: Antiblock: Yes; Slip: No Features: Good Processability; Good Strength Uses: Industrial Applications Information provided by Osterman & Company
