+ very good mechanical properties (long tifetime) + good swelling resistancy + high stiffness
- vegetable and animal oils - overheating steam - non rubber-elastic material - fluorine - Tight grooveness for sticky media (e.g. straw- - limited temperature stability
-
- aliphatic, aromatic and chlorinated - susceptible to certain detergents and disinfec- - aliphatic, aromatic and chlorinated berries) not guaranteed in PEEK-ring execution - limited form stability
hydrocarbons (e.g. mineral oil, crude oil) tants (nitric acid, formic acid or peracetic acid) hydrocarbons (e.g. mineral oil, crude oil) - expensive
- citron juices and flavors - strongly swelling in polar solvents (acetone, - critical at very cold temperatures (-20°C/-4°F)
methylcetone, ethylacetate, diethylether) - high heat expansion co-efficiant
• First choice for a multitude of applications • Dairy • Chemical processes • Aseptic process applications • Aseptic processes with very high temperatures • Aseptic process applications
TYPICAL • Wort • Special cleaning procedures (e.g pudding), so no additional elastomeric
APPLICATION • Processes with H2O2 (hydrogen peroxide) sealing element is required
AREAS • Soft drink concentrate (e.g. cola)
