When considering puller performance, an important concern is
the type of puller belt. To select the proper belt material, you
must consider the extrudate's tendency to deform under pres-
sure. For example, thin wall profiles and tubing are prone to
deformation, so you need lower pressures and longer traction
lengths to deliver the required pulling force without deforma-
tion and slippage.
Various belt materials are available: natural rubber, neoprene,
urethane, and dual material. Available belts are listed under
Conair Belts in this Appendix.
