Plastics

Nitrogen gas has various applications within the plastics processing industry. For example, it is used in manufacturing to prevent oxidation, which causes discoloration and affects the integrity of the polymer. Nitrogen can also be used as a propellant in, among other things; gas-assisted injection molding (GAIM) and extrusion.

Nitrogen for Hot Melt applications

When processing Hotmelts, nitrogen can be used to make a foam from the liquid polymer adhesive. However, it is usually used to prevent the glue from hardening / charring. This negative reaction also occurs when the product comes into contact with oxygen. This process can be counteracted by providing storage tanks with a layer of nitrogen and/or using nitrogen as a propellant during the processing of the adhesive.

Nitrogen for Hot Melt process

Avilo has been supplying systems to both large and small processors/users of hotmelts for more than 10 years. In contract of a manufacturer of hot melt systems we’ve even developed a compact generator that produces exactly the right amount and purity of nitrogen to be used at the point of use at the application head. Of course we offer a suitable generator for all types of hot melt systems.

Produce your own nitrogen for Injection Molding on-site

After injecting liquid plastic into the mold, nitrogen is added under pressure to press the plastic against the walls of the mold. The nitrogen that is pressed into the mold must be of good quality and maintain a constant pressure for the best end result.

Low Total Cost of Ownership & Fast Payback

Injection and blow molding uses relatively low purity nitrogen. Often a nitrogen purity of 98.00% is sufficient, however our experience shows that some additives or plastic compositions require a higher purity. Our nitrogen generators offer a cost-effective alternative to the expensive bulk supply of Nitrogen gas. An on-site installation pays itself back over time, regardless of the purity or capacity requirement.

Why choose Avilo?

Avilo has helped many business to succesfully protect their product quality and safety while reducing their gas costs. We’ve got multiple references with various applications, such as; Blow Film extrusion, Injection Molding and Rapid Prototyping.
