Applications
PETROTHENE NA 963 is a series of resins formulated with special antiblock additive and designed for a wide variety of industrial film applications where high impact strength and excellent drawdown are needed. NA 963 exhibits uniformity, ease of processing and good tensile strength.
Regulatory Status
The basic resin NA 963 meets the requirements of the Food and Drug Administration regulation, 21 CFR 177.1520. This regulation allows the use of this olefin polymer in "…articles or components of articles intended for use in contact with food…" Specific limitations or conditions of use may apply.
Processing Techniques
Generally recommended extrusion conditions include a melt temperature range of 310°350°F; a blow-up ratio range of 1.8-2.5:1. Drawdown to 1.0 mils is possible at commercial rates when proper extrusion techniques are used. Specific recommendations for processing NA 963 can be made only when the end use applications, required properties and processing equipment are known.
