浙江Tongyi brand No. 62 fully refined paraffin

The OIL content OF PETROLEUM wax has AN impact on many properties of petroleum wax, such as the strength of petroleum wax, hardness, softness, coefficient of friction, coefficient of expansion, abrasion resistance, pollution characteristics, melting point, etc., these effects depend on the use of Z final petroleum wax.

First, the main composition of paraffin

Paraffins are mainly composed of normal (straight chain) alkanes above C15, but also contain a small amount of isomeric alkanes or alkanes with long side chains.

Two, the melting point of paraffin

The melting point of paraffin wax is a main index to judge the grade of paraffin wax. For example, the melting point of No. 58 paraffin shall not be lower than 58℃ and no higher than 60℃.

Three, the stability of paraffin

Stability is divided into light stability and thermal stability.

The petroleum wax should have good heat and light stability. Otherwise, for a long time with hot air or direct sunlight, paraffin wax will gradually oxidize and deteriorate, the color becomes dark, and even the odor becomes large.
