浙江Tongyi brand 58 fully refined 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. 50 paraffin shall not be lower than 50℃. The melting point of paraffin is also important for practical applications. Hard wax with a melting point of not less than 52℃ is suitable for making candles. If paraffin with a melting point below 52 ° C is used to make candles, it will become soft and bent in hot weather and will stick to each other, while paraffin with a match needs only to be used with a low melting point, because it is used to infiltrate the matchstick and make it easy to burn.

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.
