Paraffin waxes sold by CEPSA are divided into three groups:
Paraffin waxes are also called macro-crystalline, i.e. they have a structure formed by large and well formed crystals, which give rise to their main characteristics: excellent insulating properties, crystalline nature, rigidity and narrow congealing point range.
CEPSA sells paraffin waxes with congealing points of between 50º and 70ºC under the brands CEPSA LUBRIPAR®, in the case of non-hydrotreated paraffin wax and CEPSA PARASUR® in the case of food grade paraffin wax.
By means of the hydrotreating process, any odour or substance harmful for people or animals is eliminated, obtaining a pure and white paraffin. Paraffins treated in this way are suitable for food use (in contact with foodstuffs) and foodstuff use (forming part of them).
They are used in manufacturing candles, waxed paper, adhesives and hundreds of other applications.
Molecules that give rise to small, irregular crystals are predominant in these, producing a relatively high congealing point, high flexibility and adhesion.
Microcrystalline waxes are sold under the brand CEPSA CERASUR®. They are hydrotreated waxes and therefore suitable for food and foodstuff use and for the cosmetic industry, among others.
They have oil contents above 30% and congealing point ranges between 30º and 70º C. They are sold under the brand CEPSA PARES® and are especially used to produce emulsions and in the fertiliser industry.
