This standard specifies a method for determining the stability of polymer dispersion and synthetic rubber latex under freeze-thaw cycles. It does not apply to natural rubber latex. The test is done by freezing the sample at low temperature for 16 hours and thawing it at room temperature for 8 hours. The sample is observed whether condensation occurs and its viscosity changes are measured. At most, sex repeability The process is 3 times to evaluate its cycle Stability. This method helps to detect the performance Stability of the material under temperature fluctuation conditions and is essential for the quality control of polymer products.
