The Advantages of Polyurethane Elastomer

DESCRIPTION


The Advantages of Polyurethane Elastomer

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 formula, so as to meet the different requirements of users for product performance. Polyurethane elastomer is a polar polymer material composed of many flexible segments and rigid segments. As the ratio of rigid segments increases and the density of polar groups increases, the original strength and hardness of the elastomer will increase accordingly.


2. Superior wear resistance. Especially under the working conditions where there are wetting media such as water and oil, its wear resistance is often several times to dozens of times that of ordinary rubber materials.


3. Various processing methods and wide applicability. Polyurethane elastomers can be molded by plasticizing, kneading and vulcanization processes (refer to MPU) like general-purpose rubbers; they can also be made into liquid rubber, cast molding or spraying, potting, centrifugal molding (referring to CPU); Pellet material, like ordinary plastic, is formed by injection, extrusion, calendering, blow molding and other processes (referring to CPU).


4. Oil resistance, ozone resistance, aging resistance, radiation resistance, low temperature resistance, good sound permeability, strong adhesion, excellent biocompatibility and blood compatibility. These advantages are the reason why polyurethane elastomers are widely used in military, aerospace, acoustics, biology and other fields.
