Polyurethane Roller - Color: Yellow

Polyurethane (PU) rollers are essential components in many industrial applications, known for their versatility, durability, and resistance to wear, chemicals, and impact. Their specific properties vary widely based on their chemical formulation, hardness (durometer), and core material. Manufacturers can produce rollers with a broad range of hardness levels, from soft and flexible to hard and rigid, to suit specific performance requirements.
Material specifications
Property Typical ValueDescription
Durometer (Hardness)10 Shore OO to 75 Shore DThe hardness of a polyurethane roller is a critical spec, determining its grip, load capacity, and wear resistance. Lower Shore A and OO values indicate softer rollers for cushioning and grip, while higher Shore D values indicate harder, more wear-resistant rollers for heavy loads.
Tensile Strength20 to 50 MPaThis measures the force required to pull the material to the point of breaking. Higher tensile strength indicates a more robust and durable roller.
Abrasion ResistanceExcellent (better than natural rubber)Polyurethane's tightly bonded molecular structure gives it exceptional resistance to wear and tear, making it ideal for high-friction applications.
Load-Bearing CapacityHighHarder polyurethane formulations are able to support significantly higher loads compared to materials like rubber, ensuring long-lasting performance.
Chemical ResistanceVaries by formulationPolyether-based urethanes offer better resistance to water, while polyester-based urethanes perform better against oils, solvents, and petroleum compounds. Specific chemical compatibility charts should be referenced for particular applications.
Temperature Resistance-40C to 80C (standard)Typical operating temperature ranges for polyurethane rollers are sufficient for most industrial needs. Special formulations can withstand higher temperatures up to 150C.
