InPolyethersulfoneIn PES material analysis, viscosity number, also known as specific viscosity, is usually measured using the Ubbelohde viscosity method. After measuring the flow time of the solution and solvent using the Ubbelohde viscometer method, calculate the final viscosity of the sample by substituting it into the formula in the standard method. Commonly used to detect specific viscosity to characterize whether product quality meets requirements.

Polyether sulfone (PES), also known as polyether phenyl sulfone, polyphenylene ether sulfone, or polyarylene ether sulfone, is a type of sulfone with excellent comprehensive propertiesThermoplastic polymer materialsIt is one of the few applications that has been widely usedSpecial engineering plasticsone of. It has excellent heat resistance, physical and mechanical properties, insulation properties, etc., especially outstanding advantages such as continuous use at high temperatures and stable performance in environments with rapid temperature changes. It has been widely used in many fields.

Polyether sulfone products have chemical resistance, non toxicity, andFlame retardancyIt has been widely applied in many fields. In recent years, with the mature development of production technology, the demand for polyether sulfone in China's market has steadily increased.

The Zhongwang fully automatic Ubbelohde viscometer is easy to operate, fast, and has high data accuracy throughout the entire experimental process, playing a key role in polymer material testing and related quality control.
