What is a thermoplastic rubber（TPR）caster?
Thermoplastic rubber (TPR) casters are a versatile and increasingly popular choice for a variety of applications, offering a unique blend of performance characteristics that make them stand out in the world of caster solutions. This article delves into the composition, properties, and applications of TPR casters, providing a compelling case for their adoption in diverse industries.
Composition and Manufacturing of TPR Casters
Thermoplastic rubber, also known as thermoplastic elastomer (TPE), is a material that combines the elasticity of rubber with the processability of thermoplastics. This dual nature allows TPR to deliver the resilience and flexibility of rubber while being easier to manufacture and recycle compared to conventional rubber. TPR casters typically consist of a TPR tread molded onto a rigid core, which may be made of materials such as polypropylene, steel, or aluminum. This design enhances durability and load-bearing capacity while maintaining smooth performance.
Is Thermoplastic Rubber (TPR) Safe?
TPR is considered a safe material for use in a wide range of applications. It is non-toxic, hypoallergenic, and free from harmful substances such as heavy metals or phthalates, making it suitable for environments where safety is a priority. In healthcare and food processing industries, TPR’s hygienic properties and resistance to contamination further enhance its safety profile. Moreover, its recyclability contributes to environmental sustainability, aligning with modern standards for eco-friendly materials.

Key Properties of TPR Casters
-
Soft and Non-Marking
TPR casters feature a soft tread that minimizes the risk of floor damage, making them ideal for sensitive surfaces such as hardwood, tile, and polished concrete. The non-marking property ensures a clean and professional appearance in environments where aesthetics matter.
-
Low Rolling Resistance
With excellent grip and low rolling resistance, TPR casters facilitate smooth and quiet movement, reducing the effort required to transport heavy loads.
-
Shock Absorption
The inherent elasticity of TPR absorbs shocks and vibrations, protecting both the load and the surface from potential damage.
-
Chemical and Temperature Resistance
TPR casters exhibit good resistance to a range of chemicals, oils, and mild solvents. Additionally, they perform well within a moderate temperature range, typically from -40°C to 80°C.
①Temperature Range: -40°C to 80°C
②Load Capacity: 50kg to 150kg per caster (varies by model)
③Tread Hardness: Shore A 60-75
-
Hygienic and Easy to Clean
The smooth surface of TPR casters resists dirt accumulation and is easy to clean, making them suitable for hygienic environments such as hospitals, laboratories, and food processing facilities.
Applications of TPR Casters
The versatility of TPR casters makes them suitable for a wide array of applications, including but not limited to:
-
Healthcare
Medical equipment, hospital beds, and carts benefit from the quiet and smooth operation of TPR casters, ensuring minimal disruption in sensitive environments.
-
Retail and Hospitality
Display racks, service carts, and trolleys equipped with TPR casters offer ease of movement and protect expensive flooring.
-
Industrial
Light-duty equipment and workstations rely on TPR casters for durability and ergonomic benefits.
-
Residential
Furniture and household items with TPR casters enhance mobility while safeguarding delicate floors.
