33-400 Black Phenolic Cap with Solid PE 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.
.030 Solid Polyethylene Lined Caps offer good chemical resistance and low moisture vapor transmission rate and is great for nail polish remover and higher concentration acids & alkalis. Good for non-oil products filled at room temperature. Because this lining system is paperless, your samples will not be contaminated with fiber or paper particles from the closure.
