Definition and Usage Area of Chlorinated paraffin

Chlorinated paraffin is a solid, sticky, colorless or yellowish, dense oil with the exception of chlorinated paraffins with a long carbon chain length (C20-C30) with a high chlorine content (70%). Chlorinated paraffins do not have the characteristic light and unpleasant odor. Odor is probably due to small amounts of product from relatively low molecular mass with a small but measurable vapor pressure. The carbon chain length and chlorine content of paraffin determine the chemical and physical properties of chlorinated paraffins. Increases in carbon chain length and degree of chlorination of certain paraffins increase viscosity and density, but reduce volatility.

Chlorinated paraffins normally contain stabilizers added to prevent degradation. Common stabilizers include Epoxidized esters and Epoxidized compounds such as soybean oils, pentaerythritol, thymol, urea, glycidyl ethers, acetonitriles, and organic phosphates.

Usage areas

• Used in the manufacture of rubber
• Used in vinyl and acrylic paints
• As a non-combustible plasticizer in PVC formulations,
• As a fire retardant additive in cable sheaths
• It is used as a high pressure additive in lubricants.
• Used as working fluid in metalworking
• Chlorinated paraffins are used as secondary plasticizers for polyvinyl chloride (PVC) and can be partially replaced by primary plasticizers such as phthalates and phosphate esters.
• Chlorinated paraffins are also used as metalworking fluids or metalworking lubricants or cutting oils as extreme pressure additives due to their adhesive qualities, compatibility with oils and their ability to release hydrochloric acid at high temperatures.
• They are added to paints, coatings and sealants to increase resistance to water and chemicals, such as in marine coatings, industrial floor coatings, coatings for containers and swimming pools.
• Chlorinated Paraffin can be used in additives in combination with chlorinated polyethylene or chlorinated rubber to impregnate textiles, especially non-combustible surface coating and natural fiber fabrics, and to waterproof synthetic fibers from contamination.
• Due to its polar properties, chlorinated paraffin is also used as lubricants for leather and similar raw materials.
• Due to its full compatibility, low volatility, good stability and non-flammability, various types of Chlorine Paraffin are used as plasticizers in the preparations of solvent and emulsion paints and varnishes.
• Adding Chlorinated Paraffin to paints or varnishes increases their hardness, gloss and resistance to acids and alkalis and increases the elasticity of the final product.
