Butyl Rubber Sheet Supplier
Famed for its impermeability to air and gas, butyl rubber is a popular choice for airtight sealing applications. Butyl rubber is a good general purpose rubber for low gas and moisture permeability, resistance to ozone, weather, abrasion, tear, flexing, heat aging, and chemical attack. Butyl rubber also has good electrical insulation performance and high shock absorption characteristics. These properties have made butyl rubber the polymer choice in a variety of applications.
What is Butyl?
A copolymer of isoprene and isobutylene, Butyl is sometimes referred to by the abbreviation IIR. It is impermeable to air and many gasses, and is often considered an airtight rubber in many applications. Inner tubes are often made from butyl, and it is also a liner on many tubeless tires.
What are the advantages of Gum Rubber?
- Airtight: If an impermeable seal is needed, butyl might fit the bill
- Inexpensive: Butyl offers tremendous seal ability, at an economical rate.
Butyl By The Numbers
| COLOR | DUROMETER | TEMPERATURE | TENSILE |
| TAN | 40 | -40 to 140F | 1/64” to 1” |
These numbers are a general guide and are subject to change at any time. Our team offers materials to meet any project. If you have special requirements for things like color, tensile, temperature, durometer, etc, please reach out to our team. Just because material listed doesn’t meet your spec does not meet it is not available.
Properties and application parameters shown throughout this datasheet are typical. Your specific application should not be undertaken without independent study and evaluation for suitability. For specific application recommendations consult Blaylock Gasket. Failure to select proper sealing products could result in property damage and/or serious personal injury.
