| PA (Nylon) |
150–250°C |
High heat deformation resistance; with glass fiber reinforcement, it can exceed 250°C. Best heat resistance. |
Baking equipment, heat treatment production lines, high-temperature industrial furnaces |
Oven caster wheels, heat treatment equipment wheels, industrial oven wheels |
| TPU (Thermoplastic Polyurethane) |
120–180°C |
Can withstand short-term baking at 160°C; higher hardness improves heat resistance. |
Automotive production lines, industrial equipment requiring heat resistance |
Automotive factory caster wheels, caster wheels for high-temperature environments |
| TPR (Thermoplastic Rubber) |
100–115°C |
Good weather resistance and UV resistance; wide temperature range (-50 to 115°C). |
Outdoor equipment, environments with large temperature fluctuations |
Outdoor warehouse cart wheels, logistics handling equipment |
| Rubber (ER) |
80–100°C |
Natural rubber ages at high temperatures; elasticity decreases with rising temperature. |
General industrial environments, indoor applications |
Ordinary hand carts, warehouse handling equipment |
| PU (Polyurethane) |
80°C |
Excellent low-temperature resistance (-35°C), but relatively limited high-temperature resistance. |
Indoor industrial environments, warehousing and logistics |
Warehouse hand carts, medical equipment carts |
| PP (Polypropylene) |
80–100°C |
Deformation temperature is 80–100°C; moderate heat resistance but cost-effective. |
Light industry, general handling scenarios |
Supermarket shopping carts, light-duty hand carts |
| PVC (Polyvinyl Chloride) |
60–80°C |
Poor heat resistance; softens and deforms at high temperatures. |
Normal indoor environments, light-load applications |
Furniture caster wheels, office chair wheels |
