Standardization of the testing method for vinyl chloride monomer in products

PVC is one of the common thermoplastic polymers well mixed up with other plasticizer, stabilizer, and additive agent. It is also a highly energy efficient material widely used in many industries related with vehicles, accessories, furniture, packaging, pipes, wallpaper, wire coating, and so on. Since it has been reported that VCM, the raw material of PVC, could be related with high of bio-carcinogenicity in human, however, the level of residual VCM not only in the polymer resins but also in the environment have been regulated in many countries. There are several testing methods for the determination of residual VCM in the polymer resins as well as environment samples, including those by ISO, ASTM, EPA, KS, and other governmental guidelines. However, it is still difficult to measure residual VCM because of its high vapor pressure. No suitable commercial reference material for VCM is another problem. To establish and develop more reliable test method for residual VCM, this paper introduces several typical standard methods for residual VCM testing in Korea and other countries.
