The issue of the acid value of chlorinated paraffins
Thread Content
This post was last edited by sunjl1981 on 2013-1-7 00:25. I have the following questions regarding the acid value of chlorinated paraffins, and I hope experienced colleagues can help answer them. 1. Is there a specific **standard** for determining the acid value of chlorinated paraffins? I’m only aware of the standards for measuring the acid value of plasticizers; I’m not sure if these apply to chlorinated paraffins as well. 2. What should be the acceptable level of acid value for qualified chlorinated paraffin products? Some manufacturers claim their products have an acid value below 0.1, but I’ve read online that the industry standard is generally below 0.05. 3. The acid value values I obtain by using the national standards for measuring the acid value of plasticizers are higher than those provided by the manufacturers. Without third-party verification, I’m not sure if there’s an error in my methods. I hope those who have done this before can share some tips on how to reduce errors and improve accuracy. Thank you in advance. # hcbbs
Chlorinated paraffins are chlorinated derivatives of paraffinic hydrocarbons, featuring low volatility, flame-retardant properties, good electrical insulation, and low cost; they can be used as flame retardants and plasticizers for polyvinyl chloride. It is widely used in the production of cable materials, flooring materials, hoses, synthetic leather, rubber, and other products. As well as additives used in coatings, lubricants, etc. Paraffin chloride 42 is a pale yellow viscous liquid. Freezing point: -30°C, relative density: 1.16 (25/25°C). Insoluble in water, soluble in organic solvents and various mineral oils. Paraffin chloride 52 is a light yellow to yellow oily viscous liquid. freezing point
