Different Classifications of Paraffin Wax

Paraffin wax is a byproduct of the oil purification process. Through a dewaxing process that crude oil undergoes, paraffin wax is derived and is then processed further for use in products.

According to application, it can be divided into food grade(food grade and packaging grade, the former is excellent) and industrial grade. Food grade is non-toxtic and industrial grade is not edible.

Crude paraffin is mainly used for making matches, fiberboard, canopy canvas, etc. due to its high oil content. When polyolefin additives are added to paraffin, the melting point is increased, and the adhesion and flexibility are increased. It is widely used in moisture-proof and waterproof packaging paper, paperboard, surface coating of certain textiles and candle production.

Semi-refined paraffin wax is a granular white solid whose relative density increases as the melting point increases. The product has good chemical stability, moderate oil content, good moistur-proof and insulation properties. The fire of candles produced by semi-refined paraffin is concentrated, smoke-free, and not irritating.

The fully refined paraffin is of white solid appearance with the from of block, granule and sheet. It has a high melting point and low oil content, therefore it does not stick at room temperature, does not sweat and has no greasy feel. It is of good chemical stability and light, good thermal stability, strong toughness, good plasticity, white color, no mechanical impurities and moisture, and no smell.

Each type of wax is divided into different varieties according to the melting point, generally every 2 ℃, such as 52, 54, 56, 58 and so on. Different melting points have effect on its properties. Nongle Industrial Group has completes kinds of paraffin wax for sale.
