Chlorinated Paraffin

Introduction

HS Code : 38122090 | CAS NO. : 85535-85-9 | UN NO. : 3082 | HAZ CLASS : 9

Packing : HDPE and MS Drum | IBC Tanks | ISO Tanks

Chlorinated Paraffin belongs to a group of Chlorinated Hydrocarbons having straight chain lengths (C_nH_{2n + 2}) with Carbon number from C10 onwards.

It is available in various grades having Chlorine content varying from 40% to 70 %. Different grades can be used for different applications.

Chlorinated paraffin's are manufactured by the chlorination of n-paraffin or paraffin wax, normally in a batch process.

The reaction is exothermic and leads to the generation of the by-product hydrochloric acid. After removing residual traces of acid, a stabilizer is added to produce finished batches.

Properties - Choice of Industries

• Flame Resistance - Exposed to high temp., CP releases significant amount of HCl and HCl contribute to formation of residue char which can function as flame poison or flame retardant.
• Plastisol Viscosity Stability - Chlorinated paraffin serves as a viscosity regulator for plastisols. This is especially critical in the manufacturing of PVC plastisol, which must maintain a stable viscosity for an extended period of time (during dip and rotational molding). For improved stability, we recommend using CPs with a chlorine content of 30%-40%.
• Low Temperature Flexibility - Chlorinated paraffin ensure greater flexibility at lower temperature than convectional plasticizer. As a result , it is often added to product that require a high flexibility in colder weather. Like Flooring, wire and cable insulation and garden hose. Production of plastics, it added to increase elasticity like PVC.
• Chemical Resistance - Chlorinated paraffin offers improved resistance to both water and chemicals. For this reason, it is often added to paints, sealants and coatings. It is especially effective in paints used for traffic markings and marine applications, such as coatings for industrial flooring, vessels, swimming pools, etc.
• Resistance to Aqueous Detergent Extraction - Many manufacturers use water-based detergents/additives to clean their metal parts. While this cleaning process eliminates contaminants like grease and oil, it can also remove plasticizers that are required for an effective formulation. Chlorinated paraffin, however, releases HCl at elevated temperatures, which then bonds with the metal surface and forms a thin yet solid film of lubricant.

Major Use & Application

• Used as a secondary plasticizer for PVC Resins, Plasticizer extender in synthetic rubber, Chlorinated rubber, Nitrocellulose Polystyrene etc.
• Used in the manufacture of PVC cables & Wires as a cost effective substitute for expensive plasticizers like DOB, DBP etc and flame retardant properties.
• Used in the manufacture of PVC hoses and pipes.
• Used in the manufacture of insulation tapes, PVC footwear, floor tiles and a host of other flexible products.
• Used in the preparation of sealants, mastics, fire proof paints and emulsion paints.
• Used in the manufacture of rexine cloths and in treatment of textiles, particularly for fireproof finishing and for waterproofing of natural fabrics.
• Used as a pressure additive to the metal working oil / lubricants used in the metal working industries.
• Widely used in gear oils for industrial and automotive applications i.e. heavy duty industrial gears, automotive hypoid gears.
