Trust Elastotec Hot Vulcanised Ceramic Lagging

Minimise Risk, Maximise Production and Reduce Downtime.

We don’t just manufacture lagging – we engineer performance. Here’s How:

The Elastotec Autoclave

Precision-controlled vulcanization for superior bond strength.

Investing in Excellence: The Elastotec Autoclave

For over a decade, Elastotec has set the industry benchmark in Hot Vulcanised Ceramic Lagging (HVCL). Our ongoing commitment to our clients has been the same from Day 1: Deliver lagging that is engineered to outlast the mechanical components of the pulley – minimising the risk to their operations, whilst helping maximise productivity and performance.

In 2012, Elastotec invested in our own autoclave – allowing for precise controls over the critical bonding and curing conditions as part of a highly robust testing process. Very few manufacturers have the commitment, the equipment and the expertise to perform this process in-house.

Unlike conventional methods, our HV process ensures that heat and pressure – essential for vulcanisation – do not degrade rubber properties or weaken the ceramic-to-rubber bond.

The result? Years of rigorous testing (over 1000 tests) have confirmed that Elastotec HVCL delivers a 100% rubber tear bond between all lagging components, with less than 5% change in ceramic to rubber adhesion strength after autoclave curing.

This is extremely difficult to achieve.

The Elastotec “HV” coloured logo is your stamp of assurance. That’s why Elastotec is the only HVCL that is Engineered to Perform: Minimise risk. Maximise production. Reduce downtime.

In-House Product Design & Manufacturing

Innovation-driven solutions for maximum longevity.

Inhouse Product Design & Manufacturing

When unplanned downtime costs hundreds of thousands of dollars, reliability isn’t just a goal – it’s a necessity. At Elastotec, we don’t take shortcuts. Instead of relying on third-party components, we design, develop and manufacture everything in-house to eliminate risks and guarantee performance.

Ever wondered why our Hot Vulcanised Ceramic Lagging (HVCL) consistently outperforms all alternatives? By maintaining full control over every variable, we can guarantee every outcome:

· We formulate our own rubber compounds in-house – specifically designed for conveyor applications
· We select and test our ceramic tiles to exact specifications
· Our ceramic-to-rubber bond system was specifically designed to cope with the hot vulcanising process, ensuring zero tile debonding (from the rubber) post autoclaving and whilst in service
· We design, test and refine our bonding systems with our own purpose-built equipment
· We manufacture in controlled conditions, in our own facility that is 100% dedicated to pulley lagging

With over a decade of continuous improvement, we’ve achieved a ‘unified’ approach to manufacturing – from compound formulation to final lagging application.

While others assemble, we engineer – ensuring our lagging outlasts the mechanical components of the pulley itself.
