Custom Butyl Rubber Sealants, Shock Mounts, and Other Parts

When shock absorption and durability is a major concern, butyl rubber is a great material for your parts. Timco Rubber works with business to design and provide customized butyl rubber products that specifically address your application’s performance needs.

Butyl Rubber: Shock Absorption, Gas Impermeability, and More

Butyl rubber offers some special capabilities to make it a potential option for applications that need quality sealing, lining, mounting, or more. This material is both incredibly durable and flexible, making it a natural solution for anyone in need of rubber parts that can endure regular agitation while maintaining seals, support, and other key tasks.

In addition to tremendous shock absorption, butyl features exceptionally low gas and moisture permeability and outstanding resistance to heat, aging, weather, ozone, chemical attack, flexing, abrasion, and tearing. It is resistant to phosphate ester based hydraulic fluids, is puncture resistant, and has excellent electrical insulation performance.

These qualities make butyl a tremendous option for a variety of applications and industries. Whether you need butyl sealants, butyl pond liners, or some other custom-made part, Timco can help. Our team works directly with you to identify your exact part needs and supply a custom solution that address both performance and budget. We strive to provide the best, most cost-effective custom rubber parts for your business, so work with Timco today to invest in the right parts for your applications.
