Bonded-Liner Caps

Bonded-Liner Caps

Polypropylene caps with bonded PTFE/low bleed silicone septa. Ideal for use with volatile solvents, corrosive chemicals and sensitive compounds.

An ultrasonic welding process bonds the liner to the cap, eliminating the risk of adhesive contamination and bond failure often associated with autoclaving or other high temperature/stress operations.

The PTFE film on the face of the liner imparts an inert, chemically resistant surface appropriate for the containment and storage of compounds, such as volatile solvents and corrosive chemicals.

The low bleed silicone has excellent resealing properties and possesses very good compression set characteristics to ensure a good seal over time.
