83-400 Black Phenolic Cap with Pulp/Vinyl 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.
Phenolic caps with pulp and vinyl liners are perfect for general use. The liner is made of a vinyl coating applied to high density polyethylene coated paper and then it is laminated to pulpboard. This general purpose liner is commonly used for food, beverage, medical and chemical applications packed at less than 120° F, including mild acids, alkalis, solvents, alcohols, oils and aqueous products. Not recommended for active hydrocarbons or bleaches.
