| Chemically, PUR D15 is based on polyester polyol + naphthylene-1.5-diisocyanate (DESMODUR® 15). PUR D15 is a high-quality polyurethane with unsurpassed abrasion and structural strength; however, it is not stable when exposed to hydrolysis. In comparison with other PUR elastomers, PUR D15 has increased resistance to heat. Short-term exposure to temperatures of up to +120 °C are possible. However, the material should not be exposed to a long-term temperature of over +100 °C. A further advantage of PUR D15 is that it has a higher modulus of elasticity in comparison with other PUR elastomers of the same Shore hardness, and thus has a higher load-bearing capacity while retaining the same deformation values. The hardness of PUR D15 is between approx. 65 Shore A to 70 Shore D.Information provided by Angst + Pfister |
