Polyurethane rubber roller has enough surface viscosity to ensure that the roller has good ink transfer and inking performance in the printing process and has become a commonly used printing equipment. The rubber rollers commonly used in our production can be divided into three categories: Let us introduce in detail its detailed category now!
1. Polyester: This type of polyurethane rubber roller high physical and mechanical properties, good solvent resistance, and more used in low and medium hardness Cots.
2. Polyether type: good water resistance, excellent low temperature resistance, good grasp of process performance, commonly used to create drawing roller, printing roller.
3. polycaprolactone type: This type of roller comprehensive superior performance, low temperature performance and hydrolysis resistance, and is commonly used as a pressing roller and a higher requirements of the roller.
Understand the above three types of polyurethane roller, we can choose according to their actual use of a suitable roller type.
