X-Ecopur
Compared to PTFE solutions, X-Ecopur® composite seals show the same material hardness but considerably lower residual deformation and need lower mounting forces. An additional benefit is the resistance to damage on assembly and installation, which can be a major problem with PTFE compounds. Also there is no requirement for sizing or calibrating the seals after assembly. Compared to standard materials harder grades show nearly the same tensile strength and elongation at break at a considerably higher 100% modulus of strain as well as higher tear strength. The tensile set is for instance on the same level as with standard materials. X-Ecopur® versions have higher extrusion resistance than standard materials and therefore allow higher pressure at same geometries. Composite seals made of X-ECOPUR® polyurethanes are an ideal alternative to PTFE solutions, if temperature range and used media do not require PTFE systems.
