Description
Application
Elastotec Diamond Rubber Lagging is designed for use in 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 mining, quarrying, mineral and metal processing industries but can be used on any conveyor pulley.
Key features and benefits
- Highly abrasion resistant rubber prevents wear on pulley shell and provides a positive drive between pulley and belt.
- Elastotec rubber compounds formulated with advanced protection systems to resist outdoor ageing and extend service life
- Dimensional and physical properties remain stable with age.
- Precision moulded 250mm strip width in a manageable size and weight makes easy installation
- Available with Hot Vulcanised bonding layer 100% rubber tear adhesion to pulley. No debonding, no shell corrosion at joints.
- Coloured diamond segments for ease of identification between NAT and FRAS lagging. Coloured segments also indicate wear.
- Fire resistant and antistatic (FRAS) rubber compound available. Can be used above or below ground.
Design
Elastotec Diamond Rubber Lagging is 250mm wide to ensure easy handling and application. It is supplied 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 10mm to 25mm.

NAT and FRAS
Elastotec Rubber and Ceramic Laggings are available in both SBR (NAT) and FRAS approved compounds. FRAS lagging is MDG3608 certified and MSHA accepted, made of a fire resistant and antistatic compound that is primarily used in applications where there is a risk of fire and/or explosion as a safety precaution. These applications include underground coal mines, power stations, grain handling facilities and sugar terminals. Elastotec uses blue coloured inserts to identify SBR (NAT) rubber products and red coloured inserts to identify FRAS rubber products.
Elastotec lagging can be applied to pulleys by cold bonding or by hot vulcanisation.
ELASTOTEC COLD BONDING
PULLEY LAGGING
Elastotec Cold Bonding Rubber Lagging has the CN buffed bonding layer packed in plastic to protect and keep it fresh and free from contamination until application to the pulley.
A rubber tear bond is achieved by using Elastotec Metal Primer 2205 and Elastotec Cold Bonding Adhesive to chemically interlock with the CN bonding layer, making a strong interface between the layers.
An Elastotec approved applicator using the Elastotec application procedure will achieve reliable adhesion levels that exceed the 9 N/mm industry standard and are typically at 12 N/mm.
ELASTOTEC HOT VULCANISING PULLEY LAGGING
Elastotec Hot Vulcanising Rubber Lagging has a 1.2mm thick uncured rubber layer applied to the back and sides of the lagging.
Hot Vulcanising Lagging is supplied packed in plastic to protect and keep the uncured bonding layer fresh and free from contamination until application to the pulley.
Application by a trained Elastotec approved applicator using the Elastotec application procedures will guarantee a 100% rubber tear bond between the lagging and the pulley shell with typical adhesion values exceeding 20 N/mm.

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:
COLD BONDING LAGGING AND WEAR PANELS
- 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
- Direct bond adhesive 2 years
Products stored under the above conditions for longer periods of time than recommended need to be re-tested for adhesion before being used. If any doubts on storage recommendations, contact Elastotec.
