Temperature Influence on Chemical Resistance of RubCon

The behavior of RubCon at elevated and negative temperatures in nonaggressive environmental operating conditions have been studied [24], Continuation of this research involves the examination of RubCon resistance in liquid corrosive environments at elevated temperatures, which showed visual destruction of the material. The combined influence of temperature and corrosive medium was determined by testing RubCon specimens measuring 4 x 4 x 16 cm. Experiments were performed in a 10% solution of caustic soda and a 30% solution of sulfuric acid at temperatures of 40°C and 60°C. Results of the experiments are illustrated in Table 2.8. 

It can be seen that the elevated temperature reduces the chemical resistance of RubCon samples and leads to their destruction due to accelerated chemical reactions between the corrosion environment and the material.
