LyondellBasell Petrothene® NA442051 Low Density Polyethylene
Categories:	Polymer; Film; Thermoplastic; Polyethylene (PE); Low Density (LDPE); Low Density Polyethylene (LDPE), Film Grade
Material Notes:	Applications PETROTHENE NA 442 is a series of low density/EVA copolymer resins for high impact/high clarity packaging and lamination applications. NA 442 exhibits excellent processability and good balance of optics and strong heat sealing characteristics. Regulatory Status NA 442 meets the requirements of the Food and Drug Administration regulation 21 CFR 177.1350. This regulation allows the use of this ethylene vinyl acetate copolymer "…in articles or components of articles intended for use in contact with food." Specific limitations or conditions of use may apply. Processing Techniques NA 442 has excellent drawdown characteristics that yield outstanding output rates. Optimum properties are obtained over a broad range of extrusion conditions at melt temperatures between 330°-380°F melt temperatures and a blow-up ratio between 1.7-3.0:1. Using proper techniques and equipment, NA 442 can be drawn to 1.0 mil at commercial production rates. Specific recommendations for the processing of NA 442 can be made only when the end use application, required properties and the processing equipment are known. Physical Properties These are typical values and not to be construed as specific product limits. Data obtained from film produced in a 3.5"(89mm) blown film line, commercially available 8"(203 mm)die, 375°F(191°C) melt extrusion temperature, 2:1 BUR, 1.25 mil (32 micron) gauge, 0.025"die gap at 130 lb/hr. This product is from the former Equistar product line.
