What is hydrolysis of TPU shoe sole?
Hydrolysis is the process by which a compound decomposes when it comes in contact with moisture. This process occurs in the soles of boots made with a compound called TPU. When the TPU in the sole is exposed to moisture or stored for a long time, it begins to decompose. Over time, this will cause the TPU in the sole of the leather boot to decompose and eventually disintegrate.
Product introduction of hydrolysis stabilizer
HyMaxTM series of anti-hydrolysis agents can react with carboxylic acids produced by TPU decomposition to produce stable urea-based compounds with no side effects. It can slow down the process of TPU hydrolysis, prolong the service life of polymer, and solve the problem of comprehensive performance degradation caused by polyester material hydrolysis.
Why an hydrolysis stabilizer for TPU shoe sole ?
TPU, as an ester based polymer materials, generally have a disadvantage. In the humid environment, especially at high temperature, the ester bond is prone to hydrolysis, thus reducing its comprehensive performance and service life. The hydrolysis of ester bond is the cause of the decrease of service life of ester-based polymer materials.
HyMaxTMseries of anti-hydrolysis agents can react with carboxylic acids produced by TPU decomposition to produce stable urea-based compounds with no side effects. It can slow down the process of TPU hydrolysis, prolong the service life of TPU, and solve the problem of comprehensive performance degradation caused by TPU hydrolysis.
