General Information

Good coefficient of sliding friction

High mechanical stability and fatigue strength

Excellent resilience

Impact resistant

Resistant to abrasion

Resistant to cold

Chemical features:

Good resistance to weak alkalis, but only moderate resistance to strong alkalis; resistant to aromatic and aliphatic hydrocarbons, fuels, mineral oils and mineral lubricants; suitable for alcohols, esters, ketones, ethers and amines

Material specification:

The polyamides are universal materials for mechanical functional parts

The temperature resistance of polyamide (from -30 to +100 °C, for a short time +120 °C) allows use in many industries

Connecting parts made of polyamide and similar plastics protect from rust and corrosion damage

Insulating properties and an amazingly high tensile strength

PA can also be used in the food processing industry and in medical fields

Resistant to corrosion and abrasion

Non-toxic and unmagnetic

Vibration-damping

PA 6.6 features the same chemical resistance as PA 6

PA 6.6 has a higher hardness, abrasion resistance, and a little higher operating temperature than PA 6

However, PA 6.6 is a little less impact resistant compared to PA 6
