What is the difference between foam wheels and titanium hollow wheels for hand trucks?

[LaJocelyn]

The differences between foam wheels and titanium hollow wheels for hand trucks: 1. Different materials: 1. Foam wheels: Foam wheels are wheels made by injection molding and foaming of plastic materials. 2. Titanium hollow wheels: Titanium hollow wheels are wheels with rubber directly vulcanized onto the rim. 2. Different wear resistance: 1. Foam wheels: Foam wheels are corrosion-resistant, anti-aging, and have good wear resistance, especially resistant to organic solvents, strong acids, and weak alkali corrosion. 2. Titanium hollow wheels: Titanium hollow wheels have poor wear resistance and are easily corroded and aged by organic solvents, strong acids, and weak alkalis. 3. Different safety levels: 1. Foam wheels: Foam wheels have low elasticity, are suitable for flat ground environments, and have relatively lower safety. 2. Titanium hollow wheels: Titanium hollow wheels have high elasticity, are suitable for harsh environments, and have relatively higher safety.
