Specifications:

Envelope:
A special rubber-impregnated fabric that offers resistance to abrasion.
It is also responsible for the total protection of all the belt's components.

Tensile Element (Tensile Cords):
Constituted of synthetic fiber cords (polyester) that guarantee total power
transmission with a very low elongation rate and high resistance to fatigue.

Compression Element:
A compound prepared to resist the fatigue of compression and to dissipate
heat generated by the system; thereby giving the belt a longer life span.

Insulating Element:
A special compound prepared to keep the tensile element connected to the
body of the belt, thus avoiding friction between the components.

Tension rubber:
A material composed of special rubber that is responsible for reducing the
possible effects of impact on the belt. It also offers better flexibility
to the system, and better adjustment of the belt to the pulley.
