Where only the toughest and hardest rubbers survive
The Linard® HD range of products are natural/synthetic rubber blends specifically designed to exhibit exceptional toughness without compromising natural elasticity. Linard® HD products are particularly suited to high impact applications or the handling of coarse aggregates, where cutting and gouging play a major part in the abrasive force.
Design Features
- Superior strength and resilience for severe abrasion
- Exceptional resistance to chunking and gouging
- Suited for dry or damp applications where there is heavy impact
Applications
- Dredge hose or duties where aggressive abrasion and/or large coarse angular particles are a major problem
- Screen decks and underpans for severe applications in the mining extractive industries
- Transfer chutes in which heavy-duty impact due to particle size is a major problem
Size/Availability
- Sheet size (to 30mm thickness): 9.25m x 1.23m nominal (approx. 30ft x 4ft)
- Sheet size (>30mm thickness): 3.05m x 1.23m nominal (approx. 10ft x 4ft)
- Part sheets available to order
- Standard thickness range: 3.0mm to 50mm (approx. 1/8” to 2.0”)
