Porex has developed a porous PTFE vent material that addresses industrial packaging requirements allowing for container integrity throughout transportation and storage.  Porex porous PTFE is a weldable, breathable, leak-resistant material solution for industrial and consumer vented cap closures, and is designed for use with solvent or water-based solutions, granular or powder chemicals, or for use with low surface tension fluids such as oils, detergents, surfactants, and more.  Porex PTFE vent materials have demonstrated compliance with UN Dangerous Goods Packaging Performance Standards* set for Packing Group II intensity with a relative density of 1.6.
