TPR is a synthetic material that combines the elasticity of rubber with the processing advantages of plastic 1. Key characteristics include:

• Excellent Elasticity and Shock Absorption: TPR is soft and elastic, allowing it to absorb shocks and vibrations effectively, providing a smooth ride for equipment .
• Superior Floor Protection: The non-marking TPR tread does not leave black marks or damage floors, unlike some traditional rubber wheels that can release sulfur and carbon black 1.
• High Durability: TPR material offers outstanding abrasion resistance and resilience, which significantly extends the caster’s service life .
• Wide Operating Temperature Range: These casters can perform reliably in a broad temperature range, typically from -50°C to 115°C, making them suitable for various indoor and outdoor environments .
• Chemical and Weather Resistance: TPR exhibits good resistance to water, many chemicals, ozone, and UV radiation, preventing premature degradation 1.

• Quiet Operation: A primary advantage is their near-silent movement, which minimizes noise pollution in quiet environments like hospitals and offices .
• Versatility and Customization: The hardness of TPR can be customized (typically from 55A to 95A) to meet specific load and performance requirements for different applications .
• Environmental Friendliness: TPR is non-toxic, recyclable, and can pass stringent environmental and safety tests (including some FDA requirements), making it a green choice 1.
• Cost-Effectiveness: The combination of long service life, low maintenance needs, and efficient production processes (like injection molding) makes TPR casters a cost-effective solution over time 1.

TPR industrial casters are widely used in settings that demand quiet operation, floor protection, and smooth maneuverability.
