Material Notes:
Description: General Notes on Saint Gobain Chemfab® TCN® Open Mesh Belting Products:
TCN belting products are PTFE coated Nomex®, a high-temperature polyamide fiber that maintains its structural integrity over its entire range of operating temperatures. These belts were developed for applications requiring continuous operation, outstanding tracking and predictable dimensional stability. TCN will not shrink or stretch--not even by 2%--under normal operating tensions.
Dimensional Stability: Width rigidity as well as length stability is maintained by TCN belting in continuous use at temperatures up to 500°F. Under normal operating tensions (3 to 10 pounds per inch of width), TCN holds its elongation and shrinkage to less than 2%.
Release Properties: The release properties of TCN equal or exceed those of any other available belting material. The PTFE makes TCN unique in its low coefficient of friction.
Chemically Resistant: The PTFE coating envapsulates the Nomex® belting carcass and enhances its useful service life.
Dynamic Strength: TCN has durability coupled with low overall belt weight, allowing optimal production speed with decreased power requirements.
Flex Fatigue Resistant: The flex fatigue resistance of Nomex--the lengthwise strength yarn in TCN belting--is unequaled by any other fiber designed for high temperature use. This flex fatigue resistance is maintained throughout the entire operating range of TCN belting.
Temperature Resistant: TCN belting can be operated continuously at temperatures up to 500°F and will still maintain 100% of its operational profile.
Low Thermal Mass: TCN belting (including the seam areas) quickly dissipates heat with low heat sink properties.
Fabrication Technology: Saint-Gobain Performance Plastics belt seams have been specifically engineered to reduce the flex fatigue failure. Substantially reduced flex fatigue means longer belt life.
Specific Notes on TCN® 2000 Belting Material: TCN 2000 is an open mesh, Leno weave belting material designed for use in forced hot air dryers. The warp yarns are Nomex®, which allows the belt to conform to machine irregularities. The filling yarn is extra heavy for maximum stiffness in the cross-machine direction. The substrate is Leno weave, with Nomex® in the warp/longitudinal direction and fiberglass in the fill/transverse direction. The substrate is coated in PTFE (PTFE = polytetrafluoroethylene). All data based on a 0.085 inch test sample.
