Chlorinated paraffin wax
Chlorinated paraffin wax
Chlorinated paraffin wax (CPW) is a set of man-made substances that have important roles in different industries. These waxes are made by treating straight-chain paraffin hydrocarbons with chlorine, giving them distinctive properties and a wide range of uses. Chlorinated paraffin wax is primarily composed of hydrocarbons, where hydrogen atoms in the paraffin chain are replaced by chlorine atoms. This chlorination process enhances the properties of the wax, such as flame resistance, chemical stability, and low volatility. The degree of chlorination can vary, leading to different grades of chlorinated paraffins with distinct characteristics.
The manufacturing process of chlorinated paraffins involves the chlorination of straight-chain paraffin hydrocarbons. This is typically achieved through the addition of chlorine gas in the presence of a catalyst. The extent of chlorination is carefully controlled to achieve the desired properties for specific applications. The process requires precision to ensure the final product meets industry standards and regulatory requirements.

- Used in leather processing
Chlorinated paraffin wax (CPW) offers several benefits across various industries:
- Flame Retardancy: CPW is widely used as a flame retardant additive in plastics, rubber, paints, and textiles. It imparts flame retardant properties to these materials, reducing their flammability and enhancing fire safety in applications such as cables, upholstery, and building materials.
- Plasticizers: CPW serves as a plasticizer in PVC (polyvinyl chloride) and other polymer formulations. It improves the flexibility, durability, and thermal stability of PVC products, making them suitable for diverse applications including flooring, pipes, wire insulation, and automotive parts.
- Metalworking Fluids: CPW is utilized as a lubricant and cooling agent in metalworking fluids, such as cutting oils and machining coolants. It helps reduce friction and heat generation during metal cutting and forming processes, extending tool life and improving machining efficiency.
- Paints and Coatings: CPW is incorporated into paints, coatings, and sealants to enhance their moisture resistance, adhesion, and weatherability. It acts as a plasticizer and binder, improving the performance and durability of these coatings in outdoor and marine environments.
