A quick reference guide to Dunlop abrasion resistant covers
AA: standard abrasion resistance for normal service conditions.
RA: abrasion resistant for more severe service conditions. Exceeds DIN Y.
RE: Excellent resistance to cuts, impact, abrasion and gouging caused by large lump sizes.
Exceeds DIN X.
RS: Extra wear resistant to meet the demands of carrying highly abrasive materials. Exceeds DIN W.
In addition to the four options listed in the quick reference guide, we also have two cover grades for belt operating conditions that involve extremely abrasive materials. Dunlop RES has similar properties as RE but has even greater wear resistance and also possesses outstanding resistance against tear (rip) propagation. Dunlop (Coldstar) RAS cover compound has the very highest resistance to abrasion with an average of 35mm³. This represents a superiority of some 150% compared to DIN W, which is the highest DIN standard for abrasion available.*
Dunlop abrasion resistant belting provides up to 50% longer wear life because the rubber covers we use exceed international quality standards by a significant margin. An excellent example of this is the Dunlop RA abrasion resistant cover, which exceeds the DIN Y standard by more than 25% and even exceeds the DIN X standard for abrasion resistance.

Dunlop Ultima can be bonded to most surfaces using the majority of good quality cold bonding systems available in the market. In applications where Ultima with an adhesive layer (AL) is used there is no need for time consuming grinding prior to bond.
