Elastotec OR FRAS can be supplied with either a Cold Vulcanised (CV) Bonding Layer or alternately a Hot Vulcanised (HV) Bonding Layer. For new pulleys or refurbished pulleys where the lagging will be done in a factory setting the HV Bonding is the preferred method as this provides a 100% rubber tear bond.
For pulleys that require lagging application in situ on the conveyor the CV Bonding system is the only option. It is important that the CV application is done using 100% Neoprene adhesive as this will have similar oil resistance to the OR FRAS lagging. The use of adhesives based on other polymers must be avoided as these may be prone to deterioration in contact with oil.
