“Temperature Effect” - Within the range of -20°C to +80°C no significant variation in performance will occur.
“Ozone” - Ozone cracking in any elastomer will occur where there are surface tensile forces. If cracking does occur, it is frequently harmless. It is simply relieving the surface tensions and further, deeper, cracking is unlikely.
“Longevity” - Due partly to their small surface area to volume ratio, and in particular the small surface area exposed to the atmosphere during service, plus the location where such strips / pads are used, bearing strips / pads of high quality natural rubber will give an extremely long life - typically longer than the structure.
“Fire Resistance” - Blocks of natural rubber do not burn easily. However, if fire resistance is considered essential, then in order to eliminate softening problems, sheathing with a suitable fire retardant, or insulating material, foam etc, is suggested. Alternatively, design to minimise any settlement if destruction by fire would cause structural problems.
Elastomeric bearing pad comes in various sizes, with a standard dimension ranging from 200 x 300, 300 x350mm to 550x550mm, and thicknesses from 10mm to 150mm. These are often used in bridge and building construction.
