Attached green thermoset (phenolic) caps are known for providing the widest range of chemical compatibility and for being the most temperature tolerant of plastic closures. The color green easily identifies the PTFE liner system. Foam-backed Polytetrafluoroethylene (PTFE) liners resist attack from virtually all chemicals at room temperature and provides resilience for a tight seal with a low moisture transmission rate. F-217 liners have a low-density foam core between two solid layers of LDPE (low-density polyethylene.) Uses include analytical lab samples, high purity chemicals, strong acids solvents, environmental samples, pharmaceuticals, and diagnostic reagents.
