8 inch Impact resistant iron core PU Heavy Duty Casters
The main differences between TPR and PU casters lie in their material properties, load-bearing capacity, wear resistance, and applicable applications. TPR is known for its elasticity and low cost, making it suitable for light-load applications. PU, on the other hand, combines high wear resistance, high load-bearing capacity, and quiet operation, making it suitable for industrial and precision equipment.
Material Properties and Structural Differences
TPR (Thermoplastic Rubber): Based on SBS, it offers excellent elasticity but low rigidity. Bonded to a frame, it can easily cause the rubber to peel or crack due to heat generation under long-term loads.
PU (Polyurethane): A material intermediate between plastic and rubber, it offers wear resistance, chemical resistance, high elasticity, and shock absorption. It can be molded using a variety of processes (injection molding, casting, etc.) and has a more stable structure.
