Trolley PU caster wheel is widely used. Polyurethane referred to as spring glue, is the abbreviation of polyurethane or isocyanate polymer. Polyurethane is a kind of high polymer material, it is a kind of elastomer interposed between plastic and rubber.
Polyurethane is an emerging organic polymer material, known as the “fifth largest plastic”. It is widely used in many fields of national economy for its superior performance. Product application areas include light industry, chemical industry, electronics, textile, medical, construction, building materials, automotive, defense, aerospace, and aviation. Polyurethane caster elastomers have:
1, Higher mechanical strength and oxidation stability;
2, Has a higher flexibility and resilience, low pressure, strong impact resistance, tear resistance, radiation resistance, high bearing capacity and shock absorption buffer;
3, With excellent oil resistance, solvent resistance, water resistance and fire resistance;
4, PU caster wheels has good wear resistance;
In addition, polyurethane wheel has excellent sound absorption characteristics, the caster will not produce noise during the movement, can achieve mute effect.
