Rubber screen panels are an alternative to polyurethane panels for applications where impact resistance is the primary requirement —?typically coarse, heavy material with high drop heights. Natural rubber's exceptional elasticity (elongation at break 500—?00%) allows it to absorb high-energy impacts from large ore lumps without cracking or chunking, providing longer life than PU in these demanding conditions.
| Parameter | Natural Rubber (NR) | SBR Rubber |
|---|---|---|
| Hardness | 40—?0 Shore A | 50—?0 Shore A |
| Tensile strength | —?8 MPa | —?5 MPa |
| Elongation at break | —?00% | —?00% |
| Impact resistance | Excellent —?best for coarse material | Good |
| Abrasion resistance | Moderate | Good |
| Temperature range | -30°C to +70°C | -20°C to +70°C |
| Aperture types | Round, slot, square —?5—?00mm | |
| Panel thickness | 25, 30, 40, 50, 65mm | |
| Panel sizes | 305×305, 305×610, 610×610mm and custom | |
| Open area | 20—?0% | |
| Noise vs wire mesh | 10—?2 dB(A) reduction | |
| Condition | Choose Rubber | Choose PU |
|---|---|---|
| Material lump size | >75mm (coarse) | <50mm (fine to medium) |
| Drop height onto screen | >1.5m (high impact) | <1m (low impact) |
| Material moisture | Dry or moderately wet | Wet —?PU has better anti-blinding |
