PS foam is the main raw material for polystyrene (PS), talc powder, calcium stearate, such as. The production process of PS is styrene monomer in high temperature and high pressure and the catalyst, the polymerization reaction in the reaction Fu sealed inside. Although styrenic benzene compounds, but the reaction is in sealing without chlorine condition so as not to produce dioxin.
　　PS foam is the direct use of PS materials, and other additives to join the butyl, through extrusion, foaming system, the production process all the physical mixing process, no chemical reaction. PS foam plastic tableware is vacuum thermoforming, immediately after molding with PE film bag packaging carton, PS foam plastic tableware is due to direct contact with food containers and their health properties must be in accordance with the requirements of the national standard (GB13119-91), so not environment with the outside contact, even in the presence of Trace Chlorine gas in the air, also won't be polluted. PS foam tableware use is currently used in packaging, have installed hot dishes when the temperature is over 100 DEG C.
　　According to the structure of the above raw materials, process, used during several aspects analysis, can be clearly seen, PS foam plastic tableware in the process of production and use, does not have, does not produce pollution will produce dioxin material impossible. So it can be concluded that PS foam tableware has nothing to do with dioxin.
