Polyurethane Wheel performance characteristics
1.Polyurethane, elastomer wheel has high bearing capacity, resilience rate excellent tensile strength, tear strength and hardness .
2. Excellent rolling resistance and maintain higher battery life .
3. Extreme resistance to cutting, high stability.
4. Oil resistance (is 3-5 multiple than NBR rubber ) ,
5. Abrasion/wear resistance (is 5 multiple than nature rubber) ;
6. PU bonding well with iron core.
