The role of high density oxidized polyethylene wax in hot melt adhesive

2022-02-24   Pageview:40

Hot melt adhesive is a kind of plastic adhesive. Its physical state changes with the change of temperature within a certain temperature range, but its chemical properties remain unchanged. It is non-toxic and tasteless, and is an environmentally friendly chemical product.

Some hot melt adhesives need to use waxes in the production process, and high density oxidized polyethylene wax itself has the following characteristics:

High Density Oxidized Polyethylene Wax in adhesive

1. Narrow molecular weight distribution, narrow melting range and stable performance
2. High softening point, good thermal stability and good heat resistance
3. Good whiteness, good transparency and low smoke;
4. Products with different viscosities can be selected and customized according to customer requirements to adjust the viscosity of hot melt adhesives.

The role of high-density oxidized polyethylene wax OA9 in hot melt adhesives generally has the following aspects: First, it is to adjust the melt viscosity. Different sizing processes have different melt viscosity, and the hot melt can be adjusted by changing the amount of wax used. The melt viscosity of the glue is suitable for different ways of using glue; the second is to adjust the curing time. The use of hot melt glue must be matched with the time of the use process, otherwise the glue with strong viscosity will not be able to exert its performance; The use can adjust the applicability of the hot melt adhesive, such as drawing phenomenon, fluidity and wetting force requirements, and prevent the storage of hot melt adhesive from agglomeration and surface stickiness.
