Casting polyurethane roller is a kind of rubber roller made of liquid polyurethane rubber by casting method.
Compared with ordinary rubber rollers,
-- it has higher mechanical strength (2-3 times that of natural rubber),
--superior wear resistance (5-10 times that of natural rubber),
-- outstanding compression resistance, and a wide range of hardness.
--And it still has high elasticity under high hardness (this is a characteristic that other rubber types do not have);
--the surface finishing is shiny;
--the machining performance is superior;
--the adhesion to metal is also much higher than that of ordinary rubber, which is more suitable for a certain line speed and high Use under pressure. The polyurethane rubber rollers have developed rapidly recently, and a large number of ordinary rubber rollers used in the past have been replaced by new polyurethane rubber rollers.
