Chemware® PTFE Laboratory Matting resists stains and adhesion of a wide range of materials and it is easy to clean. It can be used on benches, sinks, drain boards and shelves to reduce breakage of glassware. The laboratory matting has a diamond-shaped PTFE mesh and is 1/16" (1.6mm) thick with 1/4" (6.35cm) openings. Useful as a mesh bag for dipping parts in corrosive chemicals and solvents, it is also excellent as liner for cryogenic units. To create a bag, use the Chemware® PTFE cord.
