2.11 Inch Flat Free Tires Mobility Scooter Wheels Benefits of Polyurethane Tyres
1. Safety
Polyurethane bicycle tyres and Insert Tyres feature a robust structure, eliminating concerns about punctures, leaks, easy punctures, and frequent repairs, providing users with a safe and convenient experience.
2. Noise Reduction Function
Polyurethane bicycle tyres and Insert Tyres are made from microporous elastic materials with excellent rebound properties. Their microporous inner wall structure provides shock absorption and sound absorption effects, making users feel comfortable during use. When observed under a microscope magnified 400–500 times, the cross-section of the product shows that polyurethane tyres have excellent noise reduction performance.
3. Environmental Friendliness
Polyurethane tyres use a fully water-based foaming process without HFCS foaming agents, which does not adversely affect the ozone layer. Additionally, polyurethane tyres exhibit excellent biocompatibility and mould resistance, making them an outstanding eco-friendly tyre option.
4 Durability
The high performance of polyurethane bicycle tyres in terms of abrasion resistance, radiation resistance, ozone resistance, oil resistance, weather resistance, ageing resistance, and acid-alkali resistance ensures they can last at least five years, making them the ideal choice for outdoor bicycles.
