High Wear Resistance
The wear resistance of QMH Polymer Lining is significantly higher than most engineering plastics. It is approximately 5.3 times more resistant than PTFE and 6 times more than POM. In abrasive environments like iron ore or coal handling, it maintains structural integrity far longer than carbon steel.
Self-Lubrication and Anti-Sticking
The smooth surface and low friction coefficient prevent materials from bonding to the liner. This is critical for moisture-heavy materials or powdered coal, where "bridging" or "rat-holing" in silos often occurs.
Impact and Corrosion Stability
With an impact strength 5 times that of ABS, these linings absorb energy without cracking. Furthermore, the chemical stability allows the Polymer Lining to resist acids, alkalis, and oils, making it suitable for chemical reactors and tailings pipelines.
Environmental and Safety Compliance
QMH offers specialized flame-retardant and anti-static versions. Our green-certified materials produce minimal smoke and no harmful volatile gases during high-temperature exposure, ensuring a safer working environment.
Compared to traditional metal wear plates, QMH Polymer Lining offers distinct operational benefits:
The versatility of QMH Polymer Lining makes it an essential component across various sectors:
