Physical performance

1. Wear resistance

The wear resistance of polyurethane wheels is usually 4 to 5 times that of rubber wheels, and the service life can reach 3 to 10 times that of rubber wheels

Polyurethane material has an extremely low wear rate and tends to experience sliding friction, while rubber wheels are prone to producing debris

Polyurethane can be further optimized for wear resistance by adding reinforcing materials such as carbon fiber

2. Hardness and elasticity

The hardness range of polyurethane wheels is usually between Shore A 83 and 95 degrees, while the hardness of rubber wheels is between Shore A 60 and 80 degrees

High hardness gives polyurethane stronger impact resistance and tear resistance

Rubber wheels have better elasticity and can effectively absorb road impacts, providing better shock absorption effect

3. Bearing capacity

The load-bearing capacity of polyurethane wheels is about twice that of rubber wheels, with better resistance to crack growth and tear resistance

Polyurethane can maintain its shape and properties under high loads, and is not easily deformed

Rubber wheels are prone to early damage during overloaded driving

Chemical and Environmental Adaptability

1. Corrosion resistance

Polyurethane has excellent oil and chemical resistance, and performs well in sulfur-containing environments

Polyurethane used in pH 5.5 phosphoric acid environment for 6 months without corrosion

Rubber has good corrosion resistance to chemicals, but surface bubbling may occur in specific environments

2. Temperature adaptability

The upper limit of polyurethane working temperature is generally 80 to 90 degrees, and the dynamic physical properties will decrease at high temperatures

Rubber wheels can still maintain good elasticity in an environment of 25 ℃, with outstanding low-temperature adaptability

Polyurethane's resilience will decrease by about 30% in environments below 10 ℃, and its adaptability to low temperatures is weak

Performance Comparison

Performance of operational characteristics

1. Rolling resistance and energy consumption

Polyurethane wheels have lower rolling resistance and are 12% to 15% more energy-efficient than rubber wheels

Polyurethane wheels have superior starting performance and help reduce fuel consumption

Rubber wheels have relatively high rolling resistance, which increases energy consumption

2. Traction and grip performance

Rubber tires have a soft surface and a large area of ground contact marks, giving them an advantage in traction performance

Polyurethane wheels perform well on both dry and wet roads, with significantly better traction performance than rubber wheels, especially on wet roads

Polyurethane wheels can improve traction performance by adding engraved patterns

3. Noise and vibration control

Polyurethane wheels have lower operating noise, reducing noise by more than 50%

Polyurethane generates flexible friction when in contact with the ground, resulting in low vibration transmission

Rubber wheels have outstanding shock absorption performance, with vibration transmission 30% lower than polyurethane wheels

Safety and stability

1. Explosion resistance and tear resistance performance

Polyurethane wheels have excellent anti explosion performance and can effectively prevent bursting when carrying heavy loads

Polyurethane has strong resistance to cutting and tearing, and is not easily scratched when facing sharp objects

Rubber wheels have low resistance to cutting and tearing, and the cutting or tearing area is prone to elongation and expansion

2. Uniformity and stability

Polyurethane wheels have good uniformity and will not experience tread peeling

Polyurethane material has a stable chemical structure, avoiding problems such as hardening and cracking

The adhesive force of rubber wheel elastomer is difficult to eliminate and prone to deformation

Application scenario adaptation

Applicable environmental conditions

1. Ground type adaptation

Polyurethane wheels are suitable for smooth and hard surfaces, such as warehouses, shopping malls, parking lots, etc

Rubber wheels are more suitable for rough road surfaces and complex terrains, such as construction sites, mountain roads, etc

Polyurethane wheels will not cause damage to PVC floors or other surfaces that require protection

2. Temperature environment adaptation

Polyurethane wheels are suitable for ambient temperature environments, with a temperature not lower than 10 ℃

Rubber wheels are suitable for low temperature environments and can maintain good elasticity at 25 ℃

The performance of polyurethane wheels will decrease in high temperature environments, while rubber wheels have a wider temperature adaptability

Industry application selection

1. Industrial and logistics scenarios

Polyurethane wheels are suitable for high-strength, continuous production scenarios such as loaders and high-altitude work platforms

Polyurethane wheels perform excellently in smooth ground scenarios such as warehousing, logistics, and supermarket distribution

Rubber wheels are more suitable for complex working environments such as construction sites

2. Special environmental applications

Polyurethane wheels perform excellently in special environments such as cleanrooms and the semiconductor industry

Polyurethane wheels are corrosion-resistant and suitable for special scenarios such as food processing, chemical industry, cold chain, etc

Rubber wheels have better adaptability in low-temperature environments below 18 ℃, such as cold storage

Economy and Maintenance

1. Cost benefit analysis

Polyurethane wheels have a higher initial investment, but lower long-term usage costs

The procurement cost of rubber wheels is usually about 40% lower than that of polyurethane wheels

Polyurethane wheels reduce replacement frequency, saving millions of yuan annually

2. Maintenance requirement comparison

Polyurethane wheels have a long service life, reducing downtime and maintenance costs

Rubber wheels require more frequent replacement, resulting in relatively high maintenance costs

Polyurethane wheel has good aging resistance and is not prone to deformation and fracture
