The temperature failure of sodium carboxymethyl cellulose (CMC) is related to its viscosity grade. Specifically, high viscosity grades of CMC tend to fail at higher temperatures.

Generally, the temperature failure range of CMC is between 80°C and 100°C. Within this temperature range, CMC's viscosity drops significantly, losing its stability and properties.

It is worth noting that the actual temperature failure point will be affected by other factors, such as CMC concentration, pH value, heating time, etc. Therefore, in specific applications, it is necessary to test and determine the failure temperature according to actual conditions.

If you need to use CMC in a high-temperature environment, please choose a CMC level suitable for use under high-temperature conditions. It is recommended that you contact us in advance to ensure the reliability and effectiveness of its performance.
