Common uses: Gears, screws, bearings, propellers, tool shafts, door handles, machine covers, rifle butts, blocks, hoists, cable insulation etc.
Good combination of mechanical and chemical properties fatigue and creep resistance abrasion resistance – used for example for bearings and gears.
Can be used at relatively high temperatures continuously
(especially heat stabilized quality).
Polyamide 6 can be monomer cast. The method is suitable for large voltage-free details in short series.
Unfilled PAs are food approved.
All polyamides absorb or emit moisture (different for different types).
The moisture acts as a plasticizer and lowers the tensile strength, creep resistance and rigidity while increasing the impact strength and component dimensions.
The electrical properties are strongly influenced by the moisture content.
The length extension varies with temperature and moisture content.
The polyamides are attacked by strong mineral acids and acetic acid; they are dissolved by phenols. Some types are attacked by formic acid.
Oilon® is a PA 6G material with microscopically small oil droplets embedded and bound in the material. The lubricating effect remains in the surface even after machining and wear. Oilon is thus a superb material for bearings and bushings.
