Material:

Phenolic resin (Phenol Formaldehyde Resin - PF) is a durable thermoset plastic popular for its molding and physical assets. It is a result of a combined reaction between phenol and aldehyde. Known for its strength, heat, and chemical resistant abilities, phenolic resin is used to mold solids and is considered to be quite versatile, making it a good fit for a range of consumer and industrial products. Even though phenolic holds up well under certain levels of heat, phenolic caps will decompose at 220°C (428°F) or higher. Unlike other plastics, phenolic closures are capable of maintaining their form and attributes when exposed to corrosive chemicals. Phenolic caps are often used with containers that store chemicals and essential oils, making it an excellent choice for laboratories. The Cary Company stocks phenolic rod caps and various other phenolic caps with liners or inserts.
