Analysis on SVOC emission of vinyl floor covering by using micro chamber method. Part II

Abstract

The VOC and SVOC emission of vinyl floor coverings were evaluated by using both of micro chamber and small chamber method. Emission rates were determined by GC-MS and HPLC. Emission of VOC chemicals, such as, Toluene, Ethlybenzene were decreased under ventilation atmosphere. SVOC emission of phthalates, DEHP and DINP, were, however, increased. Emission of 2-Ethyl hexanol was also increased. We concluded that 2-Ethyl hexanol is supplied by hydrolysis of DEHP. SVOC emission is increased by migration of plasticizer from inside to surface of vinyl floorcovering.
