Di(2-ethylhexyl)
phthalateis
Di(2-ethylhexyl) phthalateis a main plasticizer with good intermiscibility, lower volatility and extraction, better lowtemperature softenity and resistivity to light and heat. It is widely used in the fields of soft polyvingle chloride product. It is a necessary agent in cable and medieal machinary making.
