BoKure™ is Hi-Tech Seals high-quality urethane material. The BoKure™ urethane family is composed of numerous compounds including B701, B713, B801, B831, B843, B931, B951, and MU90. These compounds offer excellent characteristics that help save customers money by increasing product longevity, equipment run time, and reducing costly maintenance.
BoKure™ urethane is a great alternative when looking to replace rubber, plastic, and metal components or where impact, corrosion, and wear is a concern. With its versatile nature BoKure™ urethane can be used for products such as rollers, spacers, protector products, impact pads, ring type joint (RTJ) gaskets for testing, and more. Our experienced staff can help design and manufacture standard or custom BoKure™ urethane components. If required, we can reverse engineer components with low tooling costs.
BoKure™ urethane advantages:
- Exceptional load-bearing ability
- Excellent cracking and tearing resistance
- Outstanding resistance to various oils and hydrolysis
- Remarkable flexural strength and abrasion resistance
