Apticote 450 nickel polymer composite logo

Apticote 450, developed in Poeton’s tribological laboratory, is a slick composite Nickel/PTFE coating that outperforms its rivals by a wide margin. The particle size of the PTFE has been reduced to sub-micron spheres, achieving the optimum % content and even distribution, giving the lowest friction coefficient without undermining the cohesion and hardness of the coating.

Key Features

High wear resistance

Apticote 450 is not only slippery; it exhibits low sliding wear. In laboratory wear tests, at 10N load against a hardened steel pin, Apticote 450 shows one tenth the wear of a standard Ni/PTFE coating. After heat-treatment, the wear rate drops by another factor of 5. And with 30N load, with its higher load capacity, Apticote 450 is 40 times better than standard Ni/PTFE. Apticote 450 also provides some non-stick properties, particularly at temperatures around 250°C where conventional polymer coatings begin to soften and char.

Low friction

Pin on disc friction tests in Poeton’s laboratory proves the exceptional low friction characteristics of the Nickel/PTFE coating, with a coefficient of friction as low as 0.07.

Smooth, even coverage

On screw threads, internal or external, coverage is precise and even. It provides uniform coverage, including corners, thread forms and bores.

Anti-galling icon

Superb anti-galling & anti-seizure

Apticote 450 excels in preventing galling and seizure when stainless steel or titanium parts are fastened together or slide.

Thickness range 5 - 20 microns

Apticote 450 is available in thicknesses from 5 to 10μm and if higher corrosion protection is required then an undercoat of Apticote 400 can be applied increasing the overall thickness to 15 to 20μm.

Diamond hardness testing icon

Good hardness

As plated, Apticote 450 has a hardness of 170-200Hv, increasing to 290-320Hv after heat treatment at 300°C. The benefit is a load-carrying capacity superior to rival Ni/PTFE coatings, with contact loads increased to 30N/mm2.
