Description
63-400 Green Thermoset Cap with F217 & PTFE Liner. Thermoset or Phenolic (Bakelite) caps are known for providing the widest range of chemical compatibility and for being the most temperature tolerant of plastic closures. They also provide the most consistent adherence to close dimensional tolerances. Ideal for pharmaceutical applications. Thermoset closures cannot be remelted after they are formed. Common “Thermoset” resins include urea, phenolic, and melamine.
F217 & PTFE Liners can resist attack from virtually all chemicals at room temperature and provide a tight seal with a low moisture transmission rate. F217 has a low density foam core between two solid layers of LDPE. Ideal for analytical lab samples, high purity chemicals, strong acids, solvents, environmental samples, pharmaceuticals, and diagnostic reagents. The color green easily identifies the PTFE liner system.
