2" x 72" Ceramic Shredder belts come in an orange/reddish color, typical of ceramic grains. The grain structure of these belts provides continuous renewal of the most consistent and uniform cutting edges. The nature of ceramic grain allows for faster cutting and cooler stock removal. They are adhered to a Y-Weight Polyester backing. A material's backing thickness (related to its flexibility) is categorized by the alphabet. Backings closer or rated as 'A' are substantially more flexible than the stiffest 'Y' weight backing you'll find on our site. Backings with an 'A', 'B', 'C', 'D', 'E', or 'F' backing are all considered paper backings. 'E' and 'F' weight backings are typically used to make belts as they are the most durable paper backings available (typically found in the wood industry) though still much less durable/thick than the full or partial synthetic backings like an 'X' or 'Y' weight. Typically various 'X' and 'Y' weight backings are used in metal working as the standard. Y weights are very sturdy and typically full synthetic polyester materials versus some 'X' weights often being a cotton-poly blend material to allow for greater flexibility. J Flex refers to an even greater flexible backing material that is often used without a contact wheel and some slack in the belt so it can softly contour rounder shapes (e.g. a wooden handle). It's important to note that our shredder sanding belts can be ran WET in grits 24, 36, 40, 60, 80 & 120.
The ceramic J-flex belts because of their backing, cannot be ran in wet applications.
