NOVA Chemicals Sclair® 99K Homopolymer HDPE Film Resin
Categories: Polymer; Film; Thermoplastic; Polyethylene (PE); High Density (HDPE); High Density Polyethylene (HDPE), Film Grade

Material Notes: 99K complies with the U.S. FDA specifications for olefin polymers and may thus be used in the United States as an article or component of an article intended for use in contact with food, without temperature or food-type restrictions, subject to technical suitability.

NOVA Chemicals' polyethylene resins are chemically and biologically inert.

Features: Excellent processability, Excellent Stretchability, High stiffness, Superior strength, Low gel

Additives: Process stabilizer, Process aid

Applications: Industrial woven bags, Tarpaulins

Film properties are typical of blown film extruded on a 2.5" extruder with 4" die and a 35-mil die gap at a blowup ratio of 2.5:1, but are dependant on operating conditions.
