Amerityre: 'Polyurethane treads stick'

Order Reprints

Amerityre Corp. says the adhesion of its polyurethane treads meets the retread industry's adhesion requirements.

Ameritye recently conducted a pull test at an independent laboratory "to test the adhesion of the polyurethane elastomer tread compound to a rubber tire casing," according to Amerityre officials.

The Boulder City, Nev.-based company is developing a retread process that "seamlessly locks" polyurethane tread to a tire casing without the application of pressure or vulcanization.

"In addition to laboratory testing, Amerityre is conducting field tests of the polyurethane elastomer retreads on a number of truck tires that are being evaluated by a mining company. If approved, the polyurethane retreads will be expanded for testing and use on heavy equipment."
