Industry Adhesives - Hot Melt Adhesive
Everyday, thousands of manufacturing and distribution companies utilize some forms of industrial adhesives on the production lines. Whether it’s packaging alcoholic beverages, binding books, assembling furniture, or stamp and envelope production, having a reliable, quality adhesive on your production line can mean the difference between high productivity and expensive production costs. But how do you know what kind of adhesive you need for your industry, and how do you find a company that produces a reliable adhesive? Keep reading the following article, and you will get a basic understanding of industrial adhesives.
Recently, there are several kinds of industrial adhesives available on the market. The most popular kind, by far, is the hot melt adhesives family. Hot melt adhesives are polymer based, and are thermoplastic in nature, meaning they are solid at room temperature. These are generally applied as either a molten film or in a series of beads that is converted to a solid form when the materials cool and set. Because hot melt adhesives do not utilize water or solvents, they also have a very fast set time, which makes them the more popular kind of industrial adhesive.
The two most popular types of hot melt adhesives are ethylene-vinyl acetate (EVA) and polyolefin, or metallocene. Let’s take a closer look at these two different types.
Ethylene-vinyl acetate (EVA): this form of hot melt adhesive works well with paper and cellulosic materials and has a wide range of formulation. These adhesives set quickly and offer strong resistance properties and operate in a moderate range of temperatures. They are used in the packaging, converting, paper, automotive, and assembly industries, and are a generally more affordable kind of hot melt adhesive.
Polyolefin: these hot melt adhesives are made with a catalyzed metallocene base, and has excellent adhesive qualities and an even faster set speed. It is also extremely resistant and services a vast range of temperatures. These adhesives are also used in the packaging, converting, and assembly industries, but are limited in their range of available formulations. Besides, they are generally more expensive, but definitely more economical on a per-use basis.
Industrial adhesives service a wide range of industries, from paper and packaging, to woodworking and the automotive industry. Hot melt adhesives, in particular, are commonly used for case and carton sealing and assembly, container labeling, and paper converting.
There are several advantages to use Hot Melt Adhesive. Hot melt adhesives have a very fast set speed, and feature moderate resistance properties. Depending on the formulation being used, they are also applicable in a wide range of temperatures and industries, and feature excellent adhesive qualities. Along with their affordability and quality, these features continue to make hot melt adhesives a more popular form of industrial adhesive currently available on the market.
