A number of physical and mechanical performance indicators can be changed within a certain range through the selection of raw materials and the adjustment of the formula, so as to meet the different requirements of users for product performance.

1. The adjustable range of performance is large.A number of physical and mechanical performance indicators can be changed within a certain range through the selection of raw materials and the adjustment of the formula, so as to meet the different requirements of users for product performance. For example, hardness is often an important indicator for users of products. Polyurethane elastomer can be made into soft printing rubber rollers with Shore A hardness of about 20 and hard steel rolling rubber rollers with Shore D hardness of more than 70, which is difficult for general elastomer materials. Polyurethane elastomer is a polar polymer material composed of many flexible segments and rigid segments. With the increase of the proportion of rigid segments and the increase of the density of polar groups, the original strength and hardness of the elastomer will increase accordingly.
