What is DOP in rubber industry?
DOP (Di-sec-Octylphthalate) is the most widely used general purpose plasticizer for the manufacture of flexible plastics (especially with PVC). It is insoluble in water and has a good stability to heat and ultraviolet light, a broad range of compatibility, and excellent resistance to hydrolysis.
Do all plastics contain phthalates?
Weirdly, not all soft plastic contains phthalates. Most plastic wraps, water bottles, and food containers are phthalate-free.
Is DOP hazardous?
Emergency overview: DOP is regulated as a hazardous chemical in North America (other countries do not regulate it). Typical of the phthalate ester group, this clear oily liquid may cause eye and skin irritation. Inhalation should be avoided.

What is dioctyl phthalate?
Dioctyl phthalate is a non-volatile solvent mainly used as a plasticizer for polymers such as polyvinyl chloride (PVC), polystyrene (PS) and polyisoprene (PI). Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
What is the compatibility limit of dioctyl phthalate with poly (ethylene oxide)?
It is known that compatibility limit of dioctyl phthalate with poly (ethylene oxide) is 15 wt%.298 Free volume increases linearly with the amount of plasticizer increasing but crystallinity of polymer changes only little. This shows that plasticizer modifies mostly amorphous phase. Figure 11.24.
What is Didi-n-octyl phthalate (DNOP)?
Di-n-octyl phthalate (DnOP) is found as a component of mixed C6-C10 linear-chain phthalates used as plasticizers in various polyvinyl chloride applications, including flooring and carpet tiles. Following exposure and absorption, DnOP is metabolized to its hydrolytic monoester, mono-n-octyl phthalate (MnOP), and other oxidative products.
