Cri-Tech's unique low fuel permeation Cri-Line® LP (Low-Permeation) FKM and Cri-plastMP™ Fluoro-TPE compounds provide the fuel resistance and lower permeation required in demanding applications.  Cri-Line® LP compounds provide this reduced permeation while not sacrificing critical properties such as tensile, hardness and compression set. 

Cri-plastMP™ Fluoro-TPE compounds provide the improved permeation performance of a fluoroplastic, with improved flexibility. 

Cri-Line® LP (Low-Permeation) FKM and Cri-plastMP™ Fluoro-TPE compounds are both available in Static dissipative formulations.
