Why use Polyurethane Lagging?

Mining companies

  • Kind to conveyor belt – abrasion resistant but does not transfer wear to belt cover
  • Longer Service Life than rubber lagging
  • Resists build up on non drive pulleys
  • Reduces operating costs
  • Elastotec developed application proceedure and “Approved Applicators” ensures a reliable result

Pulley manufacturers and refurbishment companies, conveyor maintenance companies

  • Choice of Hot Vulcanised or Cold Vulcanised bonding systems
  • Easy to apply (supplied in 250mm wide strips and rolls)
  • Elastotec developed application procedure with training supplied to “Approved Applicators”
  • Can be moulded with your company logo

Features & Benefits
