Thermoset Phenolic & Urea Caps

Thermoset Phenolic & Urea Caps

Thermoset Phenolic & Urea are known for providing the widest range of chemical compatibility and for being the most temperature tolerant of plastic closures. Thermosetting plastics (thermosets) such as phenolic resins are polymers that irreversibly cure; thus phenolic caps and closures cannot be remelted after they are formed (although some liners may melt). Thermoset and phenolic caps also provide the most consistent adherence to close dimensional tolerances. Ideal for pharmaceutical applications. Common resins include urea, phenolic, and melamine.

Qorpak carries an extensive selection of phenolic caps with a large variety of available liner systems. For help choosing the right cap and liner, see:
