Application Scope of Polyurethane Elastomers
Coal Preparation, Mining & Metallurgy Industries
Products: Screen panels, rubber rollers, tires
Features:Wear resistance, water resistance, oil resistance, vibration damping & noise reduction, high strength, strong adhesion to metal frames, low noise, effective self-cleaning, reduced screen machine load, energy savings, extended screen life, high screening quality.
Coatings, Footwear, and Potting/Repair Materials
Polyurethane offers excellent cushioning and wear resistance, so microcellular elastomers are primarily used for footwear. Polyurea elastomers are used for coatings, potting, and repair materials.
Medical Applications
Due to high strength, wear resistance, biocompatibility, and absence of plasticizers and other small-molecule inert additives, it holds significant importance in medical polymer materials. Examples: Gastroscope tubes, medical catheters, bandages, tracheal cannulas, artificial hearts, pacemakers, heart valves.
Mechanical Components
Polyurethane seals exhibit superior mechanical properties. They outperform other rubbers in wear and high-pressure resistance, with excellent aging/ozone/oil resistance. Primarily used for:
Piston rod seals in heavy-duty mobile machinery/industrial hydraulics
Vibration dampers
Connecting shafts
Polyurethane Screen Panel Advantages
Wide hardness range
Hardness adjustable range: Shore A0 to Shore D85,High load capacity at same hardness compared to other elastomers,Broad resilience range
Excellent Oil and Chemical Resistance
Polyurethane elastomers, especially polyester-based polyurethane elastomers, are strongly polar polymer materials. They exhibit low affinity with non-polar mineral oils, and are virtually unaffected in fuel oils (such as kerosene and gasoline) and mechanical oils (such as hydraulic oil, engine oil, lubricating oil), performing significantly superior to rubber.
Weathering and Oxidation Resistance
Polyurethane elastomers perform adequately in inert gases (such as nitrogen). Generally, polyurethane elastomers have a continuous service temperature range of -45°C to 90°C in air, with short-term exposure up to 120°C. At ambient temperatures, they exhibit excellent resistance to oxidation and ozone.

Analysis Application Case
A Coal Washing Plant in China
After adopting high-efficiency self-cleaning screen panels, the original design's 25mm separation size was reduced to 13mm. Statistics show:
1.Annual clean coal output increased by 452,000 tons;
2.Commercial coal calorific value improvement:
For 43 raw coal (13-25mm): +2,305.15 Kcal/kg per ton;
Overall 43 coal: +296.15 Kcal/kg;
Blended 43 & 52 commercial coal: +62.9 Kcal/kg;
3.Annual profit: RMB 41,297,500;
4.Cost savings:
Throughput of 43 coal increased from 1,200 t/h to 2,000 t/h;
Daily production time reduced by 2.8 hours, decreasing equipment wear and saving electricity consumption;
Annual electricity cost savings: RMB 1,520,000.
Note: Current screen aperture size at this plant: 8mm
