Milliken pushes new PP additives to provide brighter appearance

The chemical department of Milliken & Company designs high-performance polypropylene (PP) homopolymer additives for thermoset materials. This additive provides good physical properties while providing the product with a bright and clean appearance.

This additive Hyperform HPN 909ei complies with EU safety regulations and minimizes specific migration (SML), especially in products that come into contact with food. Compared with the previous generation product, this new type of additive Hyperform reduces SML and has a higher security guarantee. This is very important because PP homopolymers are commonly used in thermoforming beverage cups and lids, food packaging and trays. (SML refers to the maximum limit of the migration of additives from food containers and packaging materials to the food or food simulants in contact with them.)

Hyperform HPN 909ei maintains impact resistance while increasing stiffness (flexural modulus), and at the same time can shrink isotropically (similar shrinkage in both directions, thereby reducing warpage) and higher heat distortion temperature, thereby Improved heat resistance, which is essential for hot filling and microwave applications. In addition, it helps eliminate pigment nucleation and reduces design complexity.

Milliken & Company global product line manager Bhavesh Gandhi pointed out: "In fact, products using Hyperform HPN 909ei have excellent optical properties: lower haze, reduced yellowing and a cleaner appearance. This can further improve sustainability. , End users use highly recyclable polypropylene to replace other resins in various applications, with a lower overall carbon footprint.
