Description
Description
Oil Resistant (FOR) Lagging is ideally suited for use on pulleys operating on systems that convey oily materials. Elastotec Oil Resistant (FOR) Lagging is engineered to provide long service life by providing resistance to varying types of oils, while still maintaining a level of outdoor ageing and abrasion resista nce . The rubber compound also offers Fire Resistant and Anti – Static properties
Application
Elastotec Oil Resistant (FOR) Lagging is designed for use in low to medium belt tension applications, and can be applied to conveyor drive, tail, snub, bend, or take – up pulleys. It is used for conveyor system applications in the agricultural and construction processing industries when resistance to oily materials is required.
*Note: Elastotec Oil Resista nt (FOR) Lagging does have Fire Retardant and Anti – Static properties, but if FRAS/MSHA certified lagging is a requirement then the Elastotec FRAS Lagging should be used. Refer to the Elastotec website for more information on FRAS/MSHA certified lagging
Key features and benefits
- Longer service life when handling oily materials.
- Oil resistant rubber compunds that resist degradation in contact with oil.
- Resists debonding of the lagging from the pulley shell due to oil resistant bonding system.
- Can be applied using cold bond or hot vulcanised application methods.
- Ceramic lagging option resists tile loss due to oil resistant bonding system.
- Lagging has Fire Retardant and Anti-Static properties.
- Available in a range of thicknesses at 250mm wide.
- Can be supplied as bulk rolls or custom strips to suit pulley face width.
- Reduces operating costs by having a balance of oil resistant properties, combined with low abrasion and anti ageing properties.
* Note: For a Cold Bond application, oil resistant lagging needs to be applied with a neoprene based adhesive system such as the Elastotec Cold Bond Adhesive or ContiSecur BFA Adhesive. The use of adhesives based on other polymers must be avoided as these may be prone to deterioration in contact
with oil.
Design
Elastotec Oil Resistant (FOR) Lagging is 250mm wide to ensure easy handling and application. It is supplied as strips or in long roll lengths that fit on standard sized pallets to eliminate waste and for cost effective transportation and storage. It can be supplied in thicknesses from 8mm to 25mm.

Chemical Resistance
The Elastotec FOR pulley lagging exhibits good general oil resistance to common grain and vegetable based oils. The table below provides details of this oil resistance as well as a comparison with Natural Rubber & Styrene Butadiene Rubber. Elastotec FOR lagging is not recommended for use with oils where
volume swell exceeds 20%.

Storage recommendations
- Stock usage based on a first-in first-out method (FIFO).
- The storage room for lagging must be cool, dry, and dust-free.
- Avoid storage places near sources of ozone generating equipment.
- Do not store outside.
- Avoid storage in direct sunlight and strong artificial light as UV light can damage the products and may lead to a premature ageing.
- Under no circumstances should fuels, lubricants, acids, disinfectants, solvents, or other chemicals be stored in the same storage area.
- Keep the storage place clean. Protect the material from dust, water etc. with suitable coverings.
- Allow 24 hours before use when lagging is removed from cold storage
Shelf life

Stored <25°C 3 years shelf life.
Light buffing of bonding surfaces is recommended if over 4 months from production date
Hot vulcanised lagging and wear panels
<7°C and away from UV and ozone generating equipment 12 months.
Products stored for longer than 6 months will need to be re-tested for adhesion before being used, and the recommended shelf life is 12 months.
Adhesives and primers
Store in flammable goods cabinet
Stored <25°C
Shelf life:
– Primers: 2 years
– Cold bonding adhesive: 2 years
– Hot vulcanising adhesive: 12 months
