PA66 is a semi – crystalline thermoplastic material which possesses one of the highest melting points among the available polyamides on the market. Its qualities offer rigidity and consistency which are maintained at high temperatures. PA66 does not absorb moisture after moulding but retention is not high as PA6. The absorption of moisture depends on the composition of the material, the thickness of the sides and on the environmental conditions. Various modifying agents can be added to improve the mechanical properties. The addition of elastomers, for example EPDM or SBR, improves resilience. PA66 is resistant to most majority of solvents, but not to oxidising agents or strong acids.
