Polyethylene is a lightweight thermoplastic used in the many adhesive solutions throughout the medical field.
Low density and high-density polyethylene (LDPE or HDPE) adhesives have been extremely difficult to develop since bonding polyethylene is difficult to achieve.
Glue won’t stick to it, so polyethylene is often used as packaging for adhesive materials.
Since the material itself is easily attacked by solvents and susceptible to high temperatures, solvent welding, ultrasonic welding, infrared, or induction heating is the preferred method for bonding polyethylene to itself.
Industrial adhesive bonding is employed when you need to bond polyethylene to some other type of material like a plastic or other substrate (wood, metal, rubber, or composite material).
There are several options such as corona treatment, plasma treatment, or flame treatment in order to bond polyethylene. Unfortunately, these treatments require high capital expenditures, space for manufacturing, high energy costs, and specialists to oversee the process of treating HDPE. Once the surface is treated, you can then use a wide range of industrial adhesive products when bonding poly-ethylene. Industrial adhesives can also be used when dealing with untreated polyethylene.
Dermamed coatings company offers corona treatment, and other solutions, for bonding HDPE in order to help you with your adhesive solutions.
