Why use Polyurethane Lagging?

Mining companies

  • Longer Service Life than rubber lagging
  • Resists build up on non drive pulleys
  • Kind to belt – will not transfer wear to belt cover
  • Very high cut and tear resistance helps resist wear from carry back
  • Reduces operating costs
  • Elastotec developed application procedure 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 250 mm wide strips and rolls)
  • Elastotec developed application procedure with training supplied to “Approved Applicators”
  • Can be moulded with your company logo

Features & Benefits

FEATURES BENEFITS
High levels of cut and tear resistance Resists damage from carry back
Highly Abrasion Resistant PU Prevents wear on pulley shell. Positive release and dirt shedding
Precision moulded strip Optimum PU properties
Supplied in strip form 250mm wide Easy to install
Fire resistant and antistatic (FRAS) PU compound available Can be used in above or below ground applications
Strips packed in plastic film Preserves buffed bonding layer ready for application
Coloured TPU inserts Blue for standard PU. Red for FRAS PU
Low co-efficient of friction Difficult to stick to – resists build up. Kind to belt – will not transfer wear to belt cover.
