ABCON AS manufactures teflon based lube oil additives for the maritime industry

ABCON MARINE+ products are designed to reduce operating expenses of machinery by decreased wear and tear and reduced friction

In the ideal world lube oil keeps two mechanical parts from contact, but not until the velocity is high enough

Reynold’s Law applies

Conventional lube oil products have their limitsConventional lube oil products have their limits

From Pounder’s Marine Diesel Engines and GasTurbines (page 122): A typical surface finish for the cylinder liner

of a modern engine in service is around 0.5 my, while the oil film thickness of three times this value (1.5 my) - required to prevent asperety contact - may not be established until some distance down the stroke from top dead centre. The conditions for adhesive wear are therefore present at around top dead centre.

Wear metals in used lube oil show the degree of nonperformance

Micro surface picture

Before: roughness depth 0,5 μm

After: ABCON teflon particles fill the grooves -> less metal contact
