Crown Plastics’ line of DuraSurf™ UHMW-PE products are manufactured in continuous sheets and variable thicknesses, making them the perfect solution for a wide variety of material handling applications. And with the introduction of DuraSurf™ STS (Silicon Treated Surface), Crown was able to increase package flow in conveyance systems.


In material handling and fulfillment center operations, maintaining the proper constant flow rate of materials is critical. Applying DuraSurf™ STS UHWM-PE sheets to the inside of chutes and guide rails provides a very slick surface, allowing items to move smoothly through the system.


UHMW-PE is abrasion resistant and very slick, with a low coefficient of friction. DuraSurf™ STS is even more so. The addition of silicone to the UHMW-PE resin blend helps maintain abrasion resistance while improving the already low coefficient of friction. Heavy products, which normally increase belt contact and slow the system, move more freely. Energy requirements are reduced because the plastic allows the conveyor belt to function efficiently. In addition, maintenance costs to repair/replace belts and motors and conveyor system downtime are greatly reduced.

When applied to a slider bed conveyor, DuraSurf™ STS has been proven to reduce energy consumption from 15% to more than 30% while eliminating wear on the slider bed and extending the life of the belts and drives.

The incredible durability and versatility of DuraSurf™ UHMW-PE makes it a favorite among engineers and designers in nearly every industry worldwide. UHMW-PE’s long molecular chain gives it a host of exceptional attributes: high abrasion resistance, low coefficient of friction and unparalleled impact resistance, even in cryogenic environments.



DuraSurf™ STS is a revolutionary product in that it not only possesses a Silicone Treated Surface, but is also available with an adhesive backing for easy installation. The very low coefficient of friction provides a lubricated surface that is virtually maintenance free. DuraSurf™ STS is an ideal solution for many applications in the package handling industry: chute linings, slider beds, slides, spirals and numerous other areas where packages can get lodged or damaged. DuraSurf™ STS also helps reduce jamming and keeps packages moving smoothly to their ultimate destination.
