4 Roles of PE Wax in Printing Inks

Polyethylene wax can be used in PE, PP film, moisture-proof cellophane, plastic and other packaging materials for fruit sugar, milk, juice, skin care products, medicine bottles, detergents and food and other uses of ink such as offset printing ink, etc., also can be used as ink wear-resistant wear agent.

PE waxes are mainly based on the bearing effect and the floating effect. The bearing effect lies in the fact that the particle size of the PE wax itself is similar to or slightly larger than the film thickness of the ink coating and is therefore exposed, making the scratch and scuff resistance of the wax visible. The floating effect is due to the particle form of polyethylene wax powder, wax in the process of film formation drift to the surface of the coating film evenly dispersed, so that the upper layer of the coating film is protected by wax, showing the characteristics of wax scratch resistance and anti-scuffing.

The 4 roles of waxes offered by tianshiwax – pe wax manufacturer

1, Matting role: in the process of printing ink preparation, in order to improve some of the performance of printed products, need to add polyethylene in the printing ink system, to play a scratch-resistant, wear-resistant, anti-adhesive, smooth feel, etc. The big particle size of polyethylene wax, own the ability to be dispersed particles perfectly migrate to the surface layer to get the matting performance .

2, Anti-scratch, anti-abrasion, anti-polishing, anti-scoring: polyethylene wax, added to the paint can greatly reduce the tendency to be polished by abrasion, while maintaining the durability of low gloss.

3, Anti-adhesive: some workpieces such as wood pieces or metal objects, often after the coating needs to be stacked up in a short period of time, the progress of printing technology also requires the ink to avoid the scuffing of printed materials. Polyethylene wax can prevent the production or print accumulated overlap caused by the adhesion.

4, Anti-sedimentation, anti-rheology, thixotropy: the positioning of metal pigments. Polyethylene wax is dispersed in aromatic and aliphatic solvents to increase the anti-settling properties of coatings and inks, and it also shows varying degrees of thixotropy, anti-sagging and positioning of metallic pigments.

In addition, polyethylene waxes possess properties such as caking reduction, plucking and stain resistance, which improve the performance of the ink reprinting process.
