Following on from this success, Martin China recommended the use of the Elastotec Hot Vulcanised Polyurethane Lagging (HVPU) for a number of high tension non-drive pulleys. These pulleys had suffered from problems with localised debonding of lagging and material build-up due to carryback problems.
The Elastotec Hot Vulcanised (HV) bonding was a well-proven way to eliminate the debonding of the lagging. The use of polyurethane greatly increased the abrasion resistance of the lagging compared to rubber, while at the same time it provided resistance to build-up as a result of the much lower co-efficient of friction.
Once this recommendation was approved, Martin arranged for Elastotec to assist with the training and supervision of the application of the HVPU Lagging at their pulley manufacturing facility in Changzhou. In addition to developing the high performance HVPU Lagging, Elastotec have a detailed application procedure to ensure that the lagging performs exactly as designed.
Martin China have established a state-of-the-art pulley manufacturing plant in Changzhou and have invested in a PLC operated autoclave for applying hot vulcanised lagging. This state-of-the-art equipment allows Martin to control both the quality of the lagging application and the lead time.
