PU Sole Characteristics
Polyurethane sole properties
- Lightweight: 30-40% lighter than rubber
- Excellent Cushioning: Natural shock absorption reduces fatigue
- Oil Resistance: Resistant to oils and chemicals
- Good Flexibility: Maintains flexibility in cold temperatures
- Cost-Effective: Generally less expensive than rubber
- Limitations: Lower heat resistance, may wear faster on rough surfaces
Rubber Sole Characteristics
Rubber sole properties
- Superior Durability: Longer lifespan on rough surfaces
- Heat Resistance: Withstands high temperatures (up to 300°C)
- Excellent Grip: Better traction on uneven terrain
- Chemical Resistance: Resistant to acids and solvents
- Water Resistance: Natural waterproof properties
- Limitations: Heavier weight, less cushioning, higher cost
TIPFor most indoor and moderate outdoor work, PU soles provide the best balance of comfort and protection. Choose rubber for foundries, welding, or extreme outdoor conditions.
