Buying Guide for Chlorinated Paraffin + 5 Quality Tests
Have you ever purchased chlorinated paraffin that caused your final products to turn cloudy or change color? Distinguishing high-quality chlorinated paraffin from low-grade material is one of the biggest challenges for manufacturers in the plastics, cable, and synthetic leather industries. Using poor-quality paraffin not only ruins your product but can also seriously damage extruder machines.
In this article from Maad Chlor, as a specialized manufacturer, we introduce 5 key methods and simple tests to ensure the quality of your material before making a bulk purchase.
Why Is Chlorinated Paraffin (CP) Quality So Important?
Chlorinated paraffin—usually known in the market as CP52 (52% chlorine)—acts as a plasticizer and a flame retardant. If it contains impurities or lacks thermal stability:
• The final product (e.g., hose or shoe sole) may turn yellow
• It may create an unpleasant odor
• It can corrode molds and extruder cylinders
5 Golden Tests for Checking Chlorinated Paraffin Quality
To make a safe purchase, always evaluate these five factors:
1. Transparency and Color (Visual Check)
The first and simplest method is visual inspection. Good-quality CP must be fully transparent, water-white, and free of any suspended particles.
Warning sign:
If the material appears yellowish or cloudy, it has likely not been refined properly or is made from low-quality base paraffin.
2. Heat Stability Test
This is the most important test for PVC manufacturers. Pour a small amount of CP into a test tube and keep it at 175°C for about 4 hours.
• Good result: Very slight color change
• Bad result: If it turns dark brown or black, it cannot withstand processing temperatures and will darken your product.
3. Density Check
The standard density for CP52 is 1.27–1.30 g/cm³.
If the density is lower, the actual chlorine content is less than claimed and it will not provide proper flame-retardant properties.
4. Odor Test
Open the drum or bottle of the sample. High-quality CP has very little odor.
A strong, sharp, or burnt smell indicates impurities or added solvents.
5. Actual Chlorine Content
Many products are sold as “52% chlorine” but actually contain 45–48%. The only reliable method is laboratory analysis or purchasing from reputable manufacturers who provide a real COA (Certificate of Analysis).
Pro tip:
Always request a sample before placing a large order and test it directly in your production line.
Should You Buy Industrial Chlorinated Paraffin in Drums or Bulk?
This is a common question among our customers.
• Drums: Better for medium-scale users; lower risk of contamination during transport.
• Bulk (tank truck): More economical for large factories, but your storage tanks must be completely clean to avoid reducing clarity.

Where to Buy Reliable Chlorinated Paraffin?
Visual inspection alone isn’t always enough. The best choice is to buy from a producer who:
• Offers quality guarantee and product return
• Provides accurate laboratory analysis
• Offers technical consultation before purchase

Does chlorinated paraffin expire?
If stored properly (away from direct sunlight and humidity), it remains usable for up to 2 years, though it may gradually become slightly acidic.
