Combitex Backings

Combitex belts can be manufactured from most permutations of backing materials to give multi-layered belts with the desired resilience / abrasion resistance / coefficient of friction properties. Combitex belts are used where the designer needs a combination of backing properties not available from a single backing material. A typical example would be high compressibility combined with a high coefficient of friction. UraCell-LD is highly compressible but does not have a particularly high coefficient of friction and NKR is not particularly compressible but does have a high coefficient of friction. The solution to this problem is to combine two backing materials with the appropriate characteristics to give the required properties.
