Wax for Crayons

    The main components of crayons include: waxes (paraffin wax, microcrystalline wax, polyethylene wax, beeswax, ozokerite, Japanese and Brazilian carnauba wax), colorants (pigments or dyes), stearic acid (palmitic acid), tallow, fillers (kaolin, talc), etc. Water-soluble crayons contain emulsifying wax and polyethylene glycol.

    There are two main manufacturing methods for crayons: molding or extrusion (pressing through molds). Molded crayons contain low-melting-point wax. Extruded or pressed crayons have a higher proportion of fillers and greater density. "Hard" molded crayons contain polyethylene wax, which provides higher breaking strength, a smoother laying surface, easier demolding, and reduces mold surface fouling.

Application of Qihong Oxidized Polyethylene Wax in Crayons:

1. Pigment dispersant: Adding oxidized polyethylene wax to the manufacturing materials can make the pigment disperse quickly when exposed to water, enabling the pigment to bleed and spread when in contact with water.

2. Uniform dispersion to enhance color appeal.

3. As a high-melting-point wax, it can increase the softening point of paraffin wax.

4. Improve the strength and surface gloss of crayons.

5. Excellent lubricating performance for easy demolding and reduced accumulation.
