Description of standard test used to measure a membrane's ability to stop aqueous flow, and diagram of the apparatus used for water entry pressure testing.

Description of standard test used to measure airflow of low flowing media, and diagram of the apparatus used for Gurley airflow testing.

The key to choosing the appropriate membrane technology for a given application is understanding the environmental conditions and the surface tension of the fluids that the vent will encounter.

Description of standard test used to measure resistance of high flowing media, and diagram of the apparatus used for resistance testing.

Description of standard test used to measure the force required to separate the layers of a laminate, with diagrams of possible outcomes when water entry pressure has been exceeded.

Description of GORE™ Oleophobic Membranes, oil repellancy testing, oil ratings, and surface tensions of typical fluids.

A variety of methods can be used to seal GORE™ Membranes to plastic parts. This document describes two common methods: heat sealing, and ultrasonic welding.

This document lists 86 common industrial chemicals that will not compromise GORE™ Membranes. These membranes are chemically resistant to almost all industrial chemicals.
