Chlorinated Paraffin
 
Chlorinated Paraffin’s (CP) are Processed from Chlorination of paraffins of following Paraffin range:
Chlorination of Paraffin range C10 – C13
Chlorination of Paraffin range C14 – C17
Chlorination of Paraffin range C 9 – C23
Chlorination of Paraffin range pure C14

Based on Paraffin range varieties of Chlorinated Paraffin are processed which vary in volatile loss, Thermal stability, viscosity, refractive index, free mineral acidity, and colour. PH of Chlorinated Paraffins are in range of 6.0 and free Chlorine is Nil.

Shiva Group of industries are processing Paraffins for Chlorinated Paraffins as follows.
1 ) Shiva Super Premium ( SSP )
These are processed from Paraffins range of C10 - C13 and are named as:
SHIVA SUPER PREMIUM Chlorinated Paraffin NP base (SSP)
  Further each varieties are Processed based on percentage of Chlorine which is as under

Chlorination of Paraffin range C9 - C23 contains some isochain in carbon structure and are cheaper varieties and mostly are used in reprocessed and inferior grade PVC formulations.

The principal difference between SSP/SSH & other grade Chlorinated Paraffins is low degree of branching in the normal Paraffin skelton versus random branching in the Paraffin range C9- C23 . This results in advantages in heat stability and viscosity for the unbranched material..

These available products allow the vinyl formulating chemist or compounder to select material of carbon chain length ranging from about C9 to as high as C28 .The chlorination level is normally 42% to 70%. These materials can be used as high as 90% replacement of DOP. Now a days compounder processes PVC even without use of DOP /DBP with Chlorinated Paraffins as Plasticizer.Some compounder even use DBP in addition to Chlorinated Paraffins in different ratio depending upon economy and applications.

Cyclic hydro carbons are usually residue products. They may be derivatives of aromatic residues that may have been subjected to hydrogenation or alkylation .

These secondary Plasticizers are mainly used for reducing cost and hence other characteristics like heat, light stability or high volatility and compatibility shall be assessed for particular application.

Since most of paraffins are derivatives of Linear alkylene Benzene process and are dependent on quality of kerosene used in processing of normal paraffins, their specifications are indicative and variation is quite possible based an composition of Paraffin range.
 
3 ) F Grade C9 -c17
It is a substitute for the SSP grade where all the properties of SSP are not required
Higher transparency thin SSP
Economically cheaper than SSP
