Product features:

• Cellular plastic buffers made of foamed, glycol-crosslinked polyurethane
• Excellent damping properties with maximum energy absorption
• Uniform compression set behavior
• High volume compressibility with low transverse strain
• Good resistance against UV and high-energy radiation, ozone, mineral oils and lubricants
• Suitable for temperatures ranging from –40°F to 176°F (–40°C to +80°C)

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 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.
