Polyurethane Lining Board

Core Advantages

1. Superior Wear Resistance for Extended Service Life

• Excellent Wear Resistance: Its wear resistance is extremely outstanding, 3-5 times that of ordinary rubber and 5-8 times that of metal liners such as manganese steel. Under high-wear conditions such as mining and coal washing, it greatly reduces equipment loss caused by material friction, extending equipment service life by 2-4 times.

• High Impact Resistance: Polyurethane elastomer possesses a high modulus of elasticity and elongation at break (up to 600%), effectively absorbing impact energy from falling large materials without cracking or damage.

2. Lightweight Design for Reduced Energy Consumption

• Reduced Equipment Load: With a specific gravity only 1/6 to 1/7 that of steel, it is easy to install and significantly reduces the overall operating load of the equipment, effectively saving approximately 20% of electrical energy consumption.

• Easy Processing and Installation: Possesses good machinability, supporting customized operations such as cutting and drilling. It can be flexibly customized according to equipment dimensions and operating conditions, offering strong adaptability.

3. Anti-Sticking and Self-Cleaning for Smooth Operation

• Extremely Low Friction Coefficient: The surface is smooth with excellent self-lubricating properties, preventing material adhesion. In the conveying of moist or sticky materials, it effectively solves the problems of “bridging” and “blockage” in bins and chutes, ensuring production continuity.

• Protects Material Quality: In storage and conveying applications in the grain and food industries, it prevents metal impurities from mixing in, ensuring materials remain pure and uncontaminated.

4. Strong Environmental Adaptability for Safe and Durable Operation

• Oil and Corrosion Resistance: As a highly polar polymer compound, it possesses extremely strong resistance to fuel oil, mechanical oil, and various acid and alkaline media, remaining almost unaffected by corrosion.

• Safe and Stable: Special additives can be added based on operating conditions, providing excellent anti-static and flame-retardant properties, meeting fire and explosion safety requirements in harsh environments such as mines and grain silos. It also features excellent shock absorption and noise reduction capabilities, significantly improving the workshop working environment.
