Lagging Performance Specifications
COLD VULCANISED RUBBER LAGGING
Cold Vulcanised Rubber Lagging – FRAS
Rubber lagging manufactured using an abrasion resistant FRAS rubber and a buffed CN bonding layer to provide high levels of adhesion. This lagging is for use in applications where there is a risk of fire and/or explosion such as underground coal mines, and grain and sugar handling facilities and is a safety critical item.

Product code for different lengths: Add 5 digit number indicating length in mm.
| Example: | 12 mm 65m roll product code: ELA-RL-DIA-F-12-65000 |
| 15 mm 1.2m strip product code: ELA-RL-DIA-F-15-01200 |
For strips always allow 100 mm extra length over the pulley face width to have 50 mm at each end of overhang.
Thickness variation (all strips/pulley) +/-0.5mm
Rubber lagging with thickness > 15mm only recommended for pulleys with diameters over 400mm.
