Black Phenolic F217 & PTFE Lined Caps manufactured by Qorpak offer the widest range of chemical compatibility and the highest temperature tolerance of plastic closures. F-217 foam-backed PTFE liners are resistant to virtually all chemicals at room temperature and provide 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). F-217/PTFE lined caps are ideal for use with analytical lab samples, high purity chemicals, strong acids solvents, environmental samples, pharmaceuticals, and diagnostic reagents.
