Hot vulcanised v’s cold bonded lagging
The Elastotec aim is no pulley failures due to inadequate pulley lagging. Compare the difference between cold bonded and hot vulcanised lagging to see that hot vulcanised lagging is A GOOD BUSINESS DECISION.
Elastotec adhesion testing
At Elastotec, we engineer lagging solutions that keep conveyors running. Here are some causes of lagging failure.
Elastotec Direct Bond Ceramic Lagging
Elastotec Direct Bond Ceramic Lagging – application system designed to improve adhesion consistency, reduce lead times, reduce glue wastage and labour time.
Hot Vulcanised Lagging Application
Hot Vulcanised lagging application involves the chemical cross-linking of five reactive layers during the autoclave curing process. To achieve the desired 100% rubber tear adhesion all five layers must crosslink at the same time. Occasionally conditions can be created in the autoclave that prevent this happening, and result in non-uniform adhesion around the pulley circumference. This bulletin explains how these conditions occur and what needs to be done to eliminate this problem.

Elastotec Approves New Applicator in Thailand for Hot Vulcanised Ceramic Lagging (HVCL) Early in 2019 Kledkaew Inter Products Co, Ltd. a rubber lining company based in Bangkok Thailand were approached by a representative from a major power station, with a request for a pulley lagging that would significantly extend the lagging service life beyond the […]
The importance of good metal preparation to good lagging adhesion
Poor metal surface preparation Note uneven finish and the presence of machining marks – no evidence of grit blasting. The results of poor metal surface preparation – lagging debonds from the pulley shell – edge lifting and corrosion – corrosion of the pulley shell at the joints between lagging strips. Correct pulley shell surface preparation […]
