Why use oil resistant ceramic lagging?
- Longer Service Life when handling oily materials such as bitumen, tar sand and various grains.
- Resists tile loss due to oil resistant bonding system
- Resists debonding of the lagging from the pulley shell due to oil resistant bonding system
- Reduces operating costs
- Elastotec developed bonding system and application procedure and “Approved Applicators” ensures a reliable result.

CHEMICAL RESISTANCE
The Elastotec OR FRAS pulley lagging exhibits good general oil resistance to common grain and vegetable based oils. Table 2 provides details of this oil resistance as well as a comparison with Natural Rubber & Styrene Butadiene Rubber. Elastotec OR FRAS lagging is not recommended for use with oils where volume swell exceeds 20%.

BONDING SYSTEMS
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.
