TECHNICAL DATA
CHEMPLAST 818
Dioctyl Terephthalate (DOTP)
General Description and Application Physical Properties
CHEMPLAST 818 is a plasticizer based upon Molecular weight : 390
2-Ethylhexanol. It is compatible with both Flash point, closed cup : 238oC
homopolymer and copolymer vinyl resins. Boiling point, 1mm Hg : 383oC
CHEMPLAST 818 is used primarily to plasticize Pour Point : -48oC
vinyl resin where good processing characteristics Refractive index at 20oC : 1.482 – 1.488
are needed and the finished product requires Viscosity, 20oC : 50 - 70 cps
improved low temperature flexibility and low (Brookfield LVT #1/60 RPM)
volatility.
Storage and Handling
The addition of CHEMPLAST 818 to plastisols
