The manufacturing process of chlorinated paraffin (CPW)

Suntek Group continues to be a leading producer across India of innovative technology solutions that are used in multiple applications across diverse industries. Their products are widely preferred for their quality, performance, and reliability.

What is Chlorinated Paraffin (CPW):

Chlorinated Paraffin (CPW) is a colorless or yellowish oil that can be thick and viscous, depending on its concentration of chlorine. This type of petroleum offers advantages like flame retardancy and low-temperature strength, as well as increased flexibility in materials.

Usage/Applications of Chlorinated Paraffin:

Chlorinated Paraffin is widely used in several industries as plasticizers in plastics & flexible PVC manufacturing in India. It can withstand the extreme pressure additives in metalworking fluids, flame retardants and additives in the paint compounds. The major applications are summarized as under:
  • Chlorinated paraffin is commonly used as a softener in conjunction with primary plasticizers like phthalates.
  • Chlorinated paraffin offers many technical advantages, chief among them being the improved incombustibility of PVC products.
  • This can be very beneficial to your finances if you’re using PVC flooring or cables.
  • Chlorinated paraffin is also used as a plasticizer in paint, sealants, and adhesives where its stability and improved combustibility are advantages.

Demand and Scope of Chlorinated Paraffin:

  • The estimated value of the global chlorinated paraffin market is INR 12 thousand cr in 2022, and it is predicted to reach a readjusted size of INR 13 thousand cr by 2028, with a CAGR of 1.1 percent over the duration of the review period.
  • The high grades of wax (with a gas content of 70-72%) are made from a feedstock that is composed of a wax. Chlorinated paraffin is produced by chlorinating n-paraffin or petroleum oil.
  • The reaction is energetically releasing and ends up in the generation of the by-product acid. When removing residual traces of acid, a device is added to provide finished batches.
  • Chlorinated paraffin is a type of petroleum distillate that can be found in many different forms, such as liquid and gel. The majority of chlorinated paraffin used in industry comes in a liquid form, where it ranges from comparatively low to extremely high consistency.
  • There are a variety of gas-rich solid types with longer carbon chain lengths that tend to be more consistent and denser. This increased gas content leads to products with finer texture and smoother taste.
Chlorinated paraffin can easily mix with several organic solvents like acyclic and aromatic hydrocarbons, chlorinated solvents, ketones, and esters.

Manufacturing Process of CPW in India:

It is manufactured using the raw materials: paraffin and chlorine. The heated paraffin is charged to a glass-lined reactor jacketed for water cooling.
Hydrochloric acid is liberated and absorbed in water in the absorption column. The chlorinated product is sent packing in the drum.
Today, Suntek is the largest producer of CPW(Chlorinated Paraffin) in India & it constantly strives to improve in each area it enters, as its aim is to reach the pinnacle of success.
