Thermoforming Hyperform® HPN® 500ei for polypropylene: Higher stiffness and improved optics for thermoforming applications

Hyperform® HPN®-500ei is a high performance additive that provides high stiffness and improved optics to parts thermoformed from the polypropylene (PP) homopolymers that contain it.

PP resin formulated with HPN-500ei yields products such as drink cups and sheet with a reduced yellow look, offering a significantly cleaner, newer appearance that can rival that of PET.

Additionally, it helps to improve the material’s heat deflection temperature.
