New polymer offers 'step change' in seal temperature and chemical resistance(19/01/2011)
High temperature resistance, together with improvements in mechanical and chemical resistance, are now possible with the new Perlast G75TX perfluoroelastomer from Precision Polymer Engineering (PPE). Perlast G75TX is the first perfluoroelastomer to overcome the poor compression performance normally associated with perfluoroelastomers at high temperatures. An ultra-low compression set of just 8%, compared with the more typical 38%, gives the elastomer a longer, in-service life.
