Total PPH 3281 Polypropylene, Extrusion Grade
Categories: Polymer; Thermoplastic; Polypropylene (PP); Polypropylene, Extrusion Grade

Material Notes: Low melt flow homopolymer for sheet extrusion, strapping, and in-line thermoforming applications

Melt Strength – The high melt strength of FINA 3281 allows uniform drawdown during processing, resulting in maximum line speeds and a good balance of physical properties.

Process Stability – Excellent polymer stability of FINA 3281 produces consistent product properties during extrusion, even with the use of regrind.

FDA – FINA 3281 complies with all applicable FDA regulations and may be used under these provisions for food contact applications.

Recommended Applications -- FINA 3281 is recommended for sheet and strapping applications where high melt strength and high extrusion speeds are required.

Processing – FINA 3281 resin processes on conventional extrusion equipment with typical melt temperatures of 390-450°F (200-232°C)

Data provided by the manufacturer, Total Petrochemicals.

Total Petrochemicals acquired former Fina and Atofina plastics product lines.
