King Hy-Pact® is the super tough industrial polymer sheet that is environmentally stabilized with excellent physical properties. It is the product of a proprietary process called K-Stran™, the most advanced manufacturing process of quality sheets with tight tolerances and custom widths up to 60”. King Hy-Pact® has a clean white color with a smooth, non-skived finish on both sides of sheet for better material flow. It is also available in black. Tests have shown after 2,000 hours of UV exposure, King Hy-Pact® outperforms both UV stabilized HDPE and UHMW with superior toughness in wear resistance, flexibility and high-impact strength. King Hy-Pact® is the smart choice for many high abuse applications requiring superior properties, outstanding flatness and a smooth surface while providing significant cost savings compared to UHMW. Applications include, but are not limited to, food processing chutes, star wheels, fabricated parts, snowplow blades and dock fenders. The material is easy to machine and fabricate. King Hy-Pact® polymer sheet is NSF listed to meet requirements of commercial food processing operations for direct and indirect food contact.
