Polyurethane Sheathing 1.2mm Meihuan Custom PU Board

Polyurethane sheathing, polyurethane wear-resistant lining board is a high molecular material between rubber and plastic. While possessing a certain elasticity, it also has excellent wear resistance, temperature resistance, and tear resistance.

By combining polyurethane resin with inorganic non-metallic hard fillers to create composite material mill liners, it not only increases the wear resistance strength of the material but also mitigates the impact of grinding media on the liner, thereby extending the service life of the liner.

The incorporation of hard fillers can significantly reduce the cost of the liner and enhance its market competitiveness. Based on the characteristics of composite materials, different hard fillers can be added during production according to actual usage requirements to meet various application needs.

According to wear tests, the wear resistance of polyurethane composite material liners is 10 times that of steel liners and 3 times that of rubber liners, far exceeding the wear resistance of both steel and rubber liners.

Since polyurethane wear-resistant liners contain hard materials, they possess both the elasticity of rubber-like substances and the characteristics of rigid liners. Combined with their high wear resistance and good corrosion resistance, these composite liners exhibit superior wear properties.

Generally, the wear forms of ordinary liners include fatigue wear, abrasive wear, chemical corrosion, and fluid erosion. For soft liner materials like rubber, there are also rolling wear and thermal cracking wear.

Due to the high temperature resistance, excellent corrosion resistance, and high hardness of polyurethane composite liners, they generally do not suffer from thermal cracking wear, chemical wear, or rolling wear. They only experience fatigue wear, abrasive wear, and fluid erosion, thus demonstrating excellent wear resistance.

Shandong MeihuanPolyurethane Wear-Resistant Liner, Polyurethane Sheathing Advantages in Mineral ProcessingWarehouse Metallurgical Industrial Machinery Applications

1. Strong adaptability. Polyurethane wear-resistant liners can be used in environments with oil, acidic, or alkaline media, making them fully suitable for various slurry conditions in mineral processing production.

2. Lightweight. Polyurethane wear-resistant liners significantly reduce the power consumption of equipment and lessen the maintenance labor intensity for workers.
