The challenge for sealing materials is that the first two substances require a nonpolar material (EPDM) or a weakly polar material (CR) because of their strong polarity, while n-pentane requires a polar material (NBR, HNBR or FKM). In addition to an FFKM material, a CR elastomer has the best chance of meeting the resistance criteria for all three materials.  <\/p>\n","protected":false},"template":"","class_list":["post-1675","anwendungen","type-anwendungen","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/o-ring-prueflabor.de\/en\/wp-json\/wp\/v2\/anwendungen\/1675","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/o-ring-prueflabor.de\/en\/wp-json\/wp\/v2\/anwendungen"}],"about":[{"href":"https:\/\/o-ring-prueflabor.de\/en\/wp-json\/wp\/v2\/types\/anwendungen"}],"wp:attachment":[{"href":"https:\/\/o-ring-prueflabor.de\/en\/wp-json\/wp\/v2\/media?parent=1675"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
