Understanding Butyl Rubber

While all rubber may seem to be the same to the average person, those in the know understand that using the right elastomer for the right application can make all the difference in terms of performance and durability. Butyl rubber is one of the most commonly used elastomers, and for good reason. Here’s what you should know about this option.

Butyl Properties and Limitations

Butyl has been used since the 1940s thanks to its flexibility and ability to retain air. Butyl is practically impervious to gases, while also offering great resistance to common hazards such as heat, ozone, and weathering. It can be used at temperatures ranging from -50 to 250 degrees Fahrenheit, and resists many acidic and alkaline chemicals that would damage other elastomers. However, butyl has poor flame resistance and should not be used in applications where it will be exposed to petroleum and other solvents.

Common Applications For Butyl

Thanks to its impermeable nature, butyl is commonly used for tubeless tires, bladders for balls used in sports, inner tubes, and even gas masks. Its vibration dampening qualities make it a common choice for shock mounts and other vehicular body mounts. Butyl can even be used in hydraulic applications that use synthetic fluids.
