Backings can be moulded or glued. Moulded belts offer advantages over glued belts such as better abrasive performance. They don’t delaminate and they work around smaller pulleys than glued belts. Moulded belts are also multi-directional, whereas glued belts have a single, mandatory running direction.
All TransDev moulded backings are identified with ETC reference. Backings are available in ETC LXM, the next generation of Drawdown backing material. ETC is a new mix of Linatex® rubber and is available in red or light blue colours. ETC LXM B is a unique backing that resists abrasion where high temperatures are caused by friction on packaging. ETC LXM B is a problem solver for difficult to drive films.
Harder red rubber compounds are also available; for example NR60. These backings are suitable for applications where the belt backing wears quickly due to abrasion.
