Features & Benefits

Superior Impact Resistance

This LEXAN PK2870 resin offers outstanding toughness, significantly reducing breakage and failure in demanding use. It ensures your finished products, like water bottles, withstand drops and impacts, leading to lower return rates and higher customer satisfaction.

High Melt Strength

The high viscosity and melt strength of LEXAN Resin PK2870 provide excellent parison control and sag resistance during extrusion blow molding. This results in more consistent wall thickness, higher production yields, and complex part geometries with greater ease.

Food-Contact Compliant Clarity

With high light transmission (88%) and low haze, this material provides crystal-clear transparency ideal for consumer packaging. Its compliance with food contact regulations in most jurisdictions makes LEXAN PK2870 a trusted and safe choice for beverage containers.
