The Characteristics of Polyurethane Roller

The characteristics of polyurethane roller

1. First of all, from the appearance of this polyurethane roller, its color is very bright, the surface of the colloid is also very fine and smooth, and the material of the colloid can be very firmly bonded to the mandrel. The size of the rubber roller also has a certain relationship with different temperature and humidity conditions. If it can be controlled, there will be no certain changes. There are going to be too many changes. The main characteristics of polyurethane rollers are: better elasticity, better wear resistance, plus wear resistance and normal temperature working environment, etc., these are some of its characteristics.

2. The hardness of the polyurethane roller also has a certain index. Its index is relatively broad, from 35 degrees to 95 degrees. these related industries.

3. The colloid used in polyurethane rollers is relatively wear-resistant and can be used to convey some steel plates and some curled steel plates, because I can ensure that the rubber rollers have good mechanical properties, and only stable performance can ensure the quality of production.

4. The chemical properties of polyurethane rollers are also relatively good. It is suitable for various inks and printing. It has very special resistance to various cleaning agents or inks. It is also suitable for varnish rubber rollers and inks. Cots, which have good solvent resistance to diesel, gasoline and some other kerosene.

5. Polyurethane rollers also have good physical properties. If used for a long time, this polyurethane roller will not harden or age, such as the tear resistance of polyurethane rollers and its The rebound elasticity is relatively good, and it is also very wear-resistant, so it is also very easy to be preserved. Long-term storage will not affect the effect. This can withstand very high pressure. The high-speed, high-humidity environment of this production environment, polyurethane The wear resistance of rubber rollers is generally 3 times and 5 times that of natural rubber rollers; it can be permanently deformed under compression, and the resilience is also relatively good. The service life of polyurethane is more than 3 times that of ordinary rubber rollers.
