Hydrolysis Test Chamber & Vamp Ross Flexing Tester

This test chamber is suitable for performing the hydrolysis resistance test of artificial polyurethane leather, polyurethane upper and textile. It is also used to conduct rubber sole hydrolysis resistance tests and flexing tests at a given temperature and humidity.

It is capable of providing the test conditions of constant temperature and humidity (70℃ and 95% R.H) for polyurethane leathers, upper materials, textiles and rubber soles to carry out hydrolysis resistance tests and determine the resistance to flexing.

There are three test methods for the hydrolysis resistance test of polyurethane leather upper materials and fabrics. Method one is constant temperature and humidity storage: Store the specimens for at least 168 hours in a high temperature and high humidity environment. Method two is solution acceleration: Soaked in 10% NaOH for 12 ~ 72 hours under average temperature. Method three is high-temperature solution acceleration: Add 10% NaOH to a water bath at a constant temperature of 70 degrees for 1 ~ 4 hours.

Hydrolysis resistance test method of rubber sole: Store the test sample in the chamber of 70℃ and 95% RH for a certain time, then check the surface of the sole for any changes.

Under specific temperature and humidity or using the particular concentration of the solution, the specimen is placed in the chamber to conduct the test for the specified time. The operator takes out the sample to observe the surface state and variation of the properties, such as any changes in obvious lubrication, color on the surface, cracking, delamination, peeling force between layers, flexing resistance, etc.

It is also available to install various flexing devices such as the Bally flexing grips, shoe bending grips, Ross flexing grips, vamp flexing grips, sole flexing grips, etc.
