Equistar Petrothene® NA442051 Low Density Polyethylene

 

Subcategory: Polyethylene; Thermoplastic; LDPE; Polymer; Equistar Low Density Polyethylene; Equistar Polyethylene

Key Words: LDPE

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.

Certification
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. Contact your Equistar sales representative for more information.

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. For exact recommendations, please contact your Equistar representative.
