Battery seals

Vydyne® PA66 compounds have been specified in electrical and electronic applications for many years. Plastic components in these applications are subject to exacting regulatory requirements, including fire safety standards. They also must demonstrate superior mechanical and thermal performance while maintaining dimensional integrity. The performance, quality and consistency of our products make the difference in your applications.

Battery seals

A battery seal is a device that tightly seals a battery to prevent the loss of electrolytes. The plastic gasket is sealed to the cell by means of radial crimping pressure or by impact. A vent mechanism is incorporated into the gasket to release pressure and protect against cell rupture and damage in the event of misuse under abusive conditions. The vent is designed to relieve excessive gas pressure that may be generated by prolonged short-circuiting, improper disposal during a fire, charging and/or incorrect insertion in devices.

Battery seals must possess excellent chemical resistance and maintain dimensional stability throughout their design life.
