If an additive or regrind is added to the plastic product, the plastic product is entrained with ethylene, hydrogen sulfide, sulfur dioxide, amine, ammonia odor or other odor. Therefore, the general purchase of household plastic basins has an odor, which is generally a secondary processed product purchased.
The tertiary amines used in the production of polyurethane foams often give rise to strong odors and fog on the interior windows of automobiles. The solution to this problem is to find alternatives to these amines. If a polyhydroxy compound is used, the polyhydroxy compound is not only a component of the polyurethane molecular chain, but also has catalytic activity.
In many plastics, especially in plastics such as polyvinyl chloride, styrene, polyethyl acetate and acrylates, residual trace amounts of monomers can produce unpleasant odors. Those odors can be eliminated by using a resin with a small amount of monomer remaining. In addition, if a small amount of zeolite (an aluminosilicate adsorbent) is filled in the polymer, the effect of removing the odor of the material can be achieved.
