Habasit round belts are highly flexible and therefore directionally adjustable at will.  The physical and chemical characteristics are exceptional in many areas: the resistance to hydrolysis is significantly superior to the one found in most of the existing polyurethane-elastomers. So, Habasit round belts are resistant to water, oils, grease and benzine. They have a limited resistance to acids and alkaline solutions. Thanks to their close cross section tolerances, Habasit round belts guarantee uniform transmission of the number of revolutions.
