Lagging Performance Specifications
HOT VULCANISED RUBBER LAGGING
Hot Vulcanised Rubber Lagging – FRAS
Rubber lagging manufactured using an abrasion resistant FRAS rubber and an uncured bonding layer to provide high levels of adhesion. This rubber 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-12V-65000 |
| 15 mm 1.2m strip product code: ELA-RL-DIA-F-15V-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.
