What are the types of polyurethane rollers
Release time:
2023-09-27
In view of the disadvantages of poor high temperature resistance and easy hydrolysis of polyurethane rollers, the performance of polyurethane elastomers is improved by increasing the crosslinking density of elastomer molecules, increasing the degree of microphase separation and selecting raw materials such as isocyanates and chain extenders. In addition, antioxidants, heat stabilizers and some fillers are added to effectively improve the thermal stability of polyurethane elastomers.
