Description of Desired Solution

A brand new nucleating agent for PP thermoforming applications enhances the appearance of parts and sheets with higher gloss and reduced haze, offering an ideal balance of mechanical and physical properties, with excellent top load compression and improved impact resistance.

Detailed Solution Description

A new generation of PP nucleators is about to be launched! Its high flexural modulus, isotropic shrinkage and excellent aesthetics make it an ideal performance additive for thermoformed articles. First trial shows significant improvement in optical properties in sheet as well as thermoformed articles while demonstrating better ovality, top load as well as side wall compression properties than the tested benchmarks.

We are looking for collaborators from the PP industry to test this new nucleator!
