Butyl Rubber Seals Frequently Asked Questions
What makes Butyl rubber unique for sealing?
Butyl rubber offers the lowest gas permeability of any rubber material, making it ideal for applications requiring air-tight sealing or gas containment.
What temperatures can Butyl seals handle?
Butyl seals perform effectively from -40°F to 250°F, with excellent resistance to high temperatures and weather exposure.
Are Butyl seals chemical resistant?
Butyl offers excellent resistance to acids, bases, and many chemicals. It performs particularly well against ozone and weather exposure but has limited resistance to oils and hydrocarbons.
Why choose CTG’s Butyl seals?
