Total Energies Polypropylene 3281
PP(聚丙烯)
道达尔能源(Total Energies)
产品描述
Polypropylene 3281: The high melt strength of TotalEnergies Polypropylene 3281 allows uniform draw down during processing, resulting in maximum line speeds and a good balance of physical properties.
Process Stability: Excellent polymer stability of TotalEnergies 3281 produces consistent product properties during extrusion, even with the use of regrind.
FDA: 3281 has passed USP Class VI testing and complies with all applicable FDA regulations and may be used under these provisions for food contact applications.
Applications: 3281 is recommended for sheet and strapping applications where high melt strength and high extrusion speeds are required.
Processing: 3281 resin processes on conventional extrusion equipment with typical melt temperatures of 390°F-450°F (200°C-232°C).
