For many industrial buyers, the term Chlorinated Paraffin (CP) encompasses a range of products with varying properties, making the selection process complex. Understanding the different grades available is essential for optimizing formulations and achieving desired performance characteristics. As a prominent Chlorinated Paraffin manufacturer in China, we believe in empowering our customers with knowledge. This guide aims to demystify the classification of CP, helping you make informed decisions when you need to buy Chlorinated Paraffin.

Chlorinated Paraffins are primarily classified based on two key factors: the carbon chain length of the paraffin feedstock and the degree of chlorination, typically expressed as a percentage of chlorine content by weight. These classifications directly influence the physical state, viscosity, solvency, and overall performance of the CP.

Classification by Carbon Chain Length:

  • Short Chain Chlorinated Paraffins (SCCPs): These typically have carbon chains ranging from C10 to C13. SCCPs are generally more volatile and tend to be more soluble in a wider range of organic solvents. However, due to environmental and health concerns, their use is increasingly restricted in many regions.
  • Medium Chain Chlorinated Paraffins (MCCPs): With carbon chains ranging from C14 to C17, MCCPs represent a significant portion of the commercial market. They offer a good balance of properties, including excellent plasticizing and flame-retardant capabilities, making them suitable for a broad spectrum of applications like PVC products and coatings.
  • Long Chain Chlorinated Paraffins (LCCPs): These are derived from paraffin fractions with longer carbon chains, typically C18 and above. LCCPs tend to be more viscous and less soluble, often finding use in specialized applications.

Classification by Chlorine Content:

The percentage of chlorine in the molecule is a critical determinant of CP's properties. Lower chlorine content (e.g., 40-50%) generally results in more liquid and less viscous products with good plasticizing effects. As the chlorine content increases (e.g., 50-70%), the product becomes more viscous, exhibits better flame retardancy, and may even transition to a solid or waxy state at higher concentrations.

When considering 'chlorinated paraffin applications for PVC' or other industries, the combination of chain length and chlorine content is key. For instance, MCCPs with 50-52% chlorine are popular for PVC due to their effective plasticization and flame retardancy. When you search for a 'chlorinated paraffin price quote', remember that grades with different specifications will have varying price points.
