PVC celuka board will degrade under the action of light, and the process is similar to thermal degradation. The most sensitive light wave length of PVC is 270mm-310mm. Resistant to non-polar solvents such as petroleum and mineral oil. Plasticizer-free products are resistant to most inorganic acids and alkalis. It is quite stable to salts. Usually the addition of plasticizers makes PVC products eroded by solvents, and is easily eroded by bacteria in a hot and humid environment, so an anti-mold agent is required.
