CNPC Kunlun Paraffin Wax
Paraffin waxes are separated from crude oil during the production of light(distillate) lubricating oils. These waxes are categorized by oil content and the degree of refinement. The crudest versions fall into the slack wax category and contain between 5% to 20% oil. Next on the step of refinement are scale waxes containing between 1% to 5% oil. The highest grade of refinement is the fully refined wax. Fully refined paraffin waxes contain less than 0.5% oil and have been hydro treated or clay treated to remove impurities and color. The resulting waxes are water clear, odor free, and normally food grade.
Process
This is a full refined paraffin wax product made from natural crudeased oil containing wax through the process
steps of solvent deoiling and hydrotrating.
Product futures
The product is an odorless solid under ambient temperature, can be molten by heating. The product is
combustible,of low thermal and electric conductivity and strong moisture hold-up.
Suggested usages
The product is widely used in manufacturing of HF ceramic, carbon paper, stylus paper, precise casting,and
absorbing decoration plate etc, as well as in packaging, electronic, textile, candle, crayon, match and other
industry fields. In addition, it can be used as raw material, additive or modifier in fabrication of luxury candles
and various kinds of industrial or civil use candles, also as raw ingredient in formulation of face cream and
