1. Mechanical Performance: Tensile & Tear Superiority
Our TDI and MDI prepolymer casting systems allow precise control over durometer hardness from 60 Shore A to 95 Shore A. Unlike cross-linked rubber which fails via micro-crack propagation under sharp angular particles, JSLT PU absorbs impact energy and recovers elastically without surface pitting.
| Performance Parameter | Test Method | JSLT Cast PU (90A) | Natural Industrial Rubber (65A) |
|---|---|---|---|
| Tensile Strength | ASTM D412 | 42 MPa | 18 MPa |
| Tear Strength (Die C) | ASTM D624 | 110 kN/m | 35 kN/m |
| DIN Abrasion Loss | DIN 53516 | < 30 mm³ (Ultra-Durable) | 120 - 150 mm³ |
| Elongation at Break | ASTM D412 | 480% | 400% |
| Oil & Fuel Resistance | ASTM D471 | Excellent (Minimal Swell) | Poor (Degrades Rapidly) |
2. Metal-Backed & Expanded Mesh PU Liners
For heavy aggregate hoppers, we produce PU sheets integrally bonded to steel backing plates or expanded steel mesh. This composite construction allows easy bolting directly onto structural framing while eliminating liner sagging under heavy bulk loads.
❓ Frequently Asked Questions
❓ What colors of PU sheets can JSLT produce?
We cast PU in standard Amber/Red, Safety Yellow, Forest Green, Black, and Custom OEM colors upon request.
❓ Can you recoat worn industrial rollers?
Yes, we provide full roller stripping and precision polyurethane recoating with tight diameter tolerances (±0.1mm).
