Sodium phosphate, tribasic is also known as sodium hydrogen phosphate, sodium dihydrogen phosphate, and monobasic sodium phosphate. Its most common use is as a pH buffer in industrial applications, though it is also used as a stabilizer in food, a cleaning agent, a fire retardant, and a fungicide.
When rubber is exposed to sodium phosphate, tribasic, it can cause the rubber to become brittle and crack, resulting in a loss of strength and elasticity. Additionally, the rubber may become vulnerable to abrasion, tearing, and other forms of wear and tear due to its weakened state. In extreme cases, the rubber may even become discolored or warped.
