* The TX40HI45 and TX40HI75 are made from the same materials but were developed in conjunction with the U.S. EPA （Method 26） when a need arose to sample the exhaust gases from the stacks at incinerator facilities. These two grades are made with higher levels of the PTFE binder resin than the TX40HI20WW to withstand the corrosive atmosphere. The TX40HI75 has a higher level of binder than the TX40HI45 and both have a higher level than the TX40HI20WW.
