Load-Bearing Pads
Load-Bearing Pads
Urethane load-bearing pads are increasingly used in bridge construction, replacing older technology elastomers such as Natural and Exotic Rubber. Cast polyurethane polymers provide bridge designers with a bearing pad material with excellent load capabilities and superior physical properties, including tensile strength and tear resistance. Polyurethane load-bearing pads outperform rubber in abrasion resistance and resistance to deterioration.
Urethane vs. Rubber Load Bearing Pads
Unlike rubber materials, polyurethane has a high resistance to deterioration due to ozone attacks and has a much higher life expectancy. Testing to AREMA (ATSM D1149) shows that polyurethane has a 5x higher resistance to breaking down in high levels of ozone than rubber materials.
