ExxonMobil Vistamaxx 7050BF Propylene Elastomer for Nonwovens & Hygiene Applications
MFR (230°C/2.16kg): 45 g/10min
Permanent Set: 10%
✅ Nonwovens Grade
Vistamaxx 7050BF is a propylene-based elastomer specifically engineered for nonwovens and hygiene applications requiring excellent elasticity and processability. Produced using ExxonMobil’s proprietary metallocene catalyst technology, this grade is primarily composed of isotactic propylene repeat units with random ethylene distribution. It is suitable for spunbond and meltblown nonwoven processes and can be blended with PE, PP, and other polymers including styrenic block copolymers. RoHS compliant and suitable for hygiene and personal care applications.
With a low permanent set of 10% and excellent elastic recovery, Vistamaxx 7050BF delivers outstanding performance in elastic hygiene films, nonwoven laminates, and personal care products where comfort, fit, and durability are essential.
This grade offers excellent adhesion to conventional and metallocene PP and PE, good chemical resistance to aqueous systems and non-hydrocarbon based fluids, and consistent processability across a wide temperature window. Its compatibility with a broad range of polymers enables versatile formulation for tailored performance in nonwoven and film applications.
Supplied in free-flowing pellet form, Vistamaxx 7050BF is particularly suited for spunbond nonwovens, meltblown nonwovens, elastic hygiene films, and laminate applications where elasticity, softness, and processability are critical.
