The Proportion Of Polyethylene Wax(PE Wax) In Hot Melt Adhesive

2023-04-12   Pageview:183

Polyethylene wax(PE Wax) is used in hot-melt adhesives. Waxes in hot-melt adhesives are mainly used to adjust the viscosity, expand the wetting surface, increase the fluidity of the colloid, and adjust the solidification speed to achieve the purpose of fast bonding and firmness. If the viscosity of the melt glue is too high, it cannot or is not easy to flow, and it is difficult to penetrate into the signature, so it cannot be bonded firmly.


Choose different resins, choose wax is also different. Low melting point stone wax microcrystalline wax, high melting point Fischer-Tropsch wax, polyolefin wax. Polyethylene wax for hot melt adhesive is based on the wide applicability of polyolefin wax, among which polyethylene wax has good stability when used in hot melt adhesive. Compared with montan wax, it has better thermal stability. better. Therefore, there is no precipitation at high temperature, and it will not have any effect on the surface properties of the hot melt adhesive.

1. Hot melt adhesive for bookbinding:
The packaging and sealing of food, beverages, instant noodles, tobacco, beer, medicine, etc. are mostly completed with hot-melt adhesives through a sealing machine. The bookbinding industry has now abolished the old thread and staple binding, and switched to the hot-melt adhesive bonding process, which not only improves the binding quality, but more importantly, greatly speeds up the binding speed.
Mainly used for women’s hygiene products, children’s diapers, hospital bed pads, elderly incontinence products, etc. Especially the latter, with the continuous aging of my country’s population structure.
Polyethylene wax has good stability when used in hot melt adhesives, and has better thermal stability. Therefore, there is no precipitation at high temperature, and it will not have any effect on the surface properties of the hot melt adhesive. The hot melt adhesive produced by adding polyolefin wax has good cold resistance, heat resistance, acid, alkali and salt medium corrosion resistance and thermal stability, slip resistance, good fixation, high bonding strength, excellent temperature resistance, etc. features.
