Polypropylene fibers are used in a wide variety of applications such as carpets, medical, upholstery, apparel, and geotextiles.

Thermal and Processing Stability

Ciba® IRGANOX® B and Ciba® IRGASTAB® FS antioxidant systems are used to give melt stability and thermal protection to the polymer during manufacture, and during the lifetime of the fiber. Cibas' phenol free Ciba® IRGASTAB® FS systems offer improved thermal and color properties and give lower gas fade interaction.

Light Stability

Just as heat and shear can destroy polypropylene, so too can light. Ultraviolet light , the same type that causes skin to sunburn, can initiate chemical reactions in polypropylene, resulting in polymer chain scission and loss of chemical and physical properties. Ciba® TINUVIN® and Ciba® CHIMASSORB® light stabilizers can improve the light stability of polypropylene fiber. These are ultraviolet light absorbers (UVAs) or hindered amine/amide light stabilizers (HALS). Often UVAs and HALS are used together to provide a higher level of polymer light stability.
