What is chlorinated paraffin used for?
What is chlorinated paraffin used for?
Chlorinated paraffins are used as plasticizers for polyvinyl chloride, as extreme-pressure additives in metal-machining fluids, as additives to paints, coatings and sealants to improve their resistance to chemicals and to water, and as flame retardants for plastics, fabrics, paints and coatings.
Is chlorinated paraffin toxic?
Systemic Effects. Gosselin et al. (1976) report that chlorinated paraffins are “practically nontoxic” in humans with a probable oral lethal dose above 15 g/kg, or greater than 2.2 pounds, for a 70-kg person. Table 19–4 provides a summary of oral acute and short-term toxicity data for chlorinated paraffins.
How do you remove chlorinated paraffin?
There is no cleaning compound available which forces the paraffin to float on the surface and allow for removal via an oil water separation system.
How is paraffin wax synthesized?
Paraffin is manufactured by the distillation of crude petroleum or shale oil, followed by purification by acid treatment and filtration. Paraffins with different properties may be produced by controlling the distillation and subsequent congealing conditions.
How is chlorinated paraffin made?
Chlorinated paraffins are synthesized by reaction of chlorine gas with unbranched paraffin fractions (<2 % isoparaffins, <100 ppm aromatics) at a temperature of 80–100 °C. The radical substitution may be promoted by UV-light.
What is chlorinated oil?
Chlorinated paraffins are added to metalworking lubricants as extreme pressure additives. They actually react with the surface under conditions of high temperature and pressure to provide maximum lubrication. While they are excellent lubricant additives, they can be very difficult to remove.
Does paraffin clean metal?
Unfortunately, no cleaning compounds exist which can force the paraffin to remain at the surface for easy removal. The paraffin is heavier than water, so, unlike oil, it sinks….Metal Cleaning: Introduction and Use of Chlorinated Parrafin.

How does paraffin wax melt?
Paraffin wax is solid at room temperature and melts between 120°F and 150℉. It is also an odorless wax. Paraffin wax has a low viscosity, which means it moves similar to water in its liquid state.
What is paraffin C14?
Description. Sasol Chemicals C1416 Normal Paraffin is a high purity mixture of saturated alkanes in the C14 – C16 carbon range. It is high purity unhydrogenated paraffin. It is a clear, light yellow, oily liquid with a low viscosity. C1416 Normal Paraffin has an extremely low sulfur and nitrogen content.
Is paraffin flammable?
Paraffin based products such as white soft paraffin can set on fire easily. Paraffin-based products such as white soft paraffin, white soft paraffin plus 50% liquid paraffin, or emulsifying ointment that have contact with dressings and clothing are ignited easily by a naked flame.
