4000 PAI Based

Meldin® 4000 is Omniseal Solutions™ material line of PAI (polyamide-imide) based compounds. The different numbers within the series refer to the unique composition and different properties of the various compounds. 

Meldin® 4000 grades are manufactured by injection molding that can meet tight tolerances. There is also a limited number of shapes available for prototyping activities.

All of the 4000 series formulations have common properties that make them suitable replacements or metal components: they are stiff and retain high mechanical strength at elevated temperatures; they are very durable even in harsh applications in regards to wear, and they are chemically compatible with many fluids (e.g., fuels and oils).

Meldin® 4000 grades have excellent fatigue resistance: when exposed to cyclical stress (loading or vibration), the material keeps very high tensile and flexural mechanical properties. In addition, the material has excellent wear resistance.
