20/400 Green Melamine Cap with F217 & PTFE Liner

These caps provide a wide range of chemical compatibility. The F-217 foam-backed PTFE liners resist attack from virtually all chemicals at room temperature and provide odor and impact resilience for a tight seal with a low moisture transmission rate. F-217 has a low-density foam core between two solid layers of LDPE (low density polyethylene). Green Melamine Caps: the compound from which the part is molded is an alpha-cellulose filled melamine-formaldehyde condensation resin. Some uses for these F-217/PTFE lined caps include analytical lab samples, high purity chemicals, strong acid solvents, environmental samples, pharmaceuticals, and diagnostic reagents.
