*In April 2018, several specifications for individual Aspire PTFE Membranes were revised based on improved characterization equipment and procedures. Membrane characterization has no impact on the manufacturing process for the membranes, and no change in performance should be expected.

* NOTE:

QP (Polyester) products max operating temp is 170°C for short term use and 130 - 150°C for continuous use.

QL (Polypropylene) products max operating temp is 130°C for short term use and 80°C for continuous use.

PTFE products max operating temp is 260°C.
