3M307 Gates Polyflex Belt

Construction

• Polyurethane compound, superior to conventional belt materials, offers high fatigue and wear resistance and a high friction coefficient. It also improves adhesion to the tensile cords.
• Polyurethane is extremely resistant to heat, chemicals and oil.
• Uniformity throughout Polyflex® is ensured because the polyurethane compound is not layered but cast as a single unit after the positioning of the tensile cords in the mould.
• Ribbed top provides lateral rigidity without increasing bending stresses. The ribs also help to keep Polyflex® belts running cool.
• 60° angle results in better support of the tensile section, and provides a more even load distribution.

Advantages

• Design freedom and space savings which are not possible with
• conventional rubber construction belts.
• Low maintenance cost as belt needs less re-tensioning.
• Long belt life on compact drives.
