Choosing Belt Materials
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 pressure. 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 deformation and slippage.
Various belt materials are available: natural rubber, neoprene, urethane, and dual
material. Available belts are listed under Conair Belts in this Appendix.
