4"x36YD Ultra High Molecular Weight (UHMW) Polyethylene tape with an aggressive acrylic adhesive that is chemical and abrasion resistant. This product has an extremely low coefficient of friction which makes it a versatile engineering material where one needs materials to slide freely across without snags or hang ups. It has high impact strength and shock absorbing properties and is more abrasion-resistant than steel. It outwears PTFE film or tape many times and is a good less expensive substitute when high temperatures are not a factor. It is nicknamed "guide rail tape"; because it is used on conveyors, chutes, guide rails, and hopper liners to prevent wear of the equipment and to protect the product from damage. 5 mil and 10 Mil thicknesses meet automotive specs: Chrysler MS-CH612, Ford ESB-M3G123-B, and GM 6419M. 3, 5 and 10 mil thickness come on a white paper liner and 20 Mil comes on a blue poly liner. The product is clear on a plastic core. This item usually ships from the manufacturer in 3-5 days. 2 roll minimum order.
