DUREL cellular plastic buffers – unsurpassed quality for the industrial sector, for example for mechanical engineering, crane and material handling applications
Elastomer buffers are subject to natural aging caused by ozone, UV radiation or hydrolysis. They need to be inspected regularly for signs of aging, for example during an annual crane inspection. Due to varying environmental conditions no general statements about the expected service life of this product can be made.
The diagrams below illustrate the hydrolysis aging of polyester urethane when stored in water that is heated to 176°F (80°C).
In polyester-based polyurethane, however, hydrolytic damage progresses very slowly at room temperature.
We guarantee the high DUREL quality standards that our customers have come to expect from us for all products in our portfolio. In addition, we exclusively continue to distribute part of the proven and familiar “NO 16xxx” and “NO 20xxx” buffer and accessory product ranges formerly sold by RIW Maschinenbau GmbH that are compliant with relevant DIN standards or RIW factory standards. Each component conforms to the corresponding RIW factory standard.
