Description

King Hy-Pact® is the super tough industrial polymer sheet that is environmentally stabilized with excellent physical properties. 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® has a clean white color with a smooth, non-skived finish for better material flow. King Hy-Pact® is produced in K-Stran™, our advanced proprietary manufacturing process of quality sheets with tight tolerances and custom widths up to 60”.  Applications include, but are not limited to, food processing chutes, star wheels, fabricated parts, snowplow blades and dock fenders. 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.
