What are the applications for high-temperature polyurethane casters?

High-temperature polyurethane casters, with modified formulas and optimized structures, can withstand short-term or sustained high temperatures of 120-150°C (some custom models can reach 180°C). Their applications are primarily focused on areas with high temperature requirements and the need for both wear resistance and vibration damping. 

First, high-temperature areas on industrial production lines. Examples include the high-temperature drying section of an automotive paint shop and areas surrounding electronic component reflow soldering lines. In these environments, equipment (such as material transfer carts and workpiece racks) frequently travels through high temperatures of 80-120°C. High-temperature polyurethane casters can withstand high temperatures, preventing the tread from softening and sticking. Their inherent elasticity can also cushion ground vibrations, preventing workpiece displacement or damage. Their wear resistance also withstands the long-term wear of cement floors in workshops.

Second, they are used in the food and pharmaceutical processing industries. The ambient temperature in bakery tray transfer carts and pharmaceutical freeze-drying workshops, often between 90-130°C, often requires high hygiene standards. High-temperature polyurethane casters not only withstand high temperatures, but their smooth surface and resistance to impurities also reduce bacterial growth, meeting the hygiene standards of the food and pharmaceutical industries while also avoiding the risk of harmful substances released by ordinary casters at high temperatures.

Third, high-temperature storage areas in warehousing and logistics. For example, in glassware warehouses and semi-finished rubber warehouses, storage temperatures can reach 80-100°C due to material heat dissipation and environmental temperature control requirements. Forklifts and flatbed carts used to transport materials require high-temperature casters. These casters can stably carry heavy loads and resist deformation at high temperatures, ensuring efficient logistics handling and avoiding transport interruptions caused by heat damage to ordinary casters.

Fourth, high-temperature environments in laboratories and testing facilities. In material aging test rooms and metal heat treatment laboratories, carts used to transport test samples and testing equipment must be used in short-term high-temperature environments of 120-150°C. High-temperature-resistant polyurethane casters are suitable for these intermittent high-temperature working conditions. Their shock-absorbing properties protect precision testing equipment and reduce vibration interference during handling.

Fifth, outdoor high-temperature working environments. For example, in outdoor storage docks in tropical regions and open-air auto repair shops in summer, ambient temperatures often exceed 40°C, and the ground temperature can reach 60-80°C after exposure to sunlight. Mobile tool carts used to transport tools and accessories require high-temperature casters. These casters can withstand direct sunlight and high ground temperatures, preventing tread aging and cracking, and extending their service life during outdoor use.
