In the ever-expanding world of industrial manufacturing, chlorinated paraffins (CP) are uniquely positioned as versatile and cost-effective secondary plasticizers. These intriguing compounds, also known as chlorinated paraffin oil (CPO) and Chlorinated Paraffins Wax (CPW), find wide applications in soft PVC products, making them valuable in modern manufacturing.
What are Chlorinated Paraffins?
Chlorinated paraffins are complex mixtures created by chlorinating straight-chain paraffins/waxes of different lengths. They act as secondary plasticizers in soft PVC formulations, working with primary plasticizers to provide unique properties such as fire retardancy.
Classification and Manufacturing
Chlorinated paraffins are classified according to their carbon chain length and percentage of chlorination. These are manufactured through an exothermic reaction controlled between 80-100°C. Depending on the chlorine content, they can vary from colorless liquids to waxy solids.
Difference Between CP and CPW
Though the terms CP and CPW are used interchangeably, the distinction lies in the length of hydrocarbon chains. CP has a chain containing 10-16 carbon atoms, while CPW has a longer chain of 20-40 carbon atoms.
Characteristics of CP/CPW
Flexibility: Providing good low-temperature flexibility, CP is valuable in various applications.
Resistance: CP’s resistance to stains and aqueous detergent extraction makes it suitable for flooring, wall coverings, and upholstery.
Compatibility: CP’s compatibility with plasticizers varies based on chlorine content, making it a versatile component.
Storage: Proper storage away from sunlight and specific metals is crucial to maintain CP’s color and stability.
Thermal & UV Stability: Though CP offers many benefits, considerations must be made regarding its effect on PVC’s thermal and UV stability.
Flammability and Flame Retardancy: CP’s ability to reduce flammability and act as a flame retardant is a significant attribute.
Cost Reduction: CP’s cost-effective nature enables manufacturers to reduce costs without compromising performance.
In line with REACH regulations, the use of short-chain CP must be limited, while medium-chain CPs are not restricted. This compliance ensures that CP can be used responsibly in various products.
Chlorinated paraffins, with their wide range of applications and unique characteristics, remain a vital component in modern manufacturing. Understanding CP’s properties, classification, compatibility, storage considerations, and regulatory compliance are essential for industries aiming for excellence and innovation.
