High performance PA46-GF, FR widely used on various auto parts

Nylon 46 (nylon 4-6, nylon 4/6 or nylon 4,6, PA46, Polyamide 46) is a high heat resistant polyamide or nylon. DSM is the only commercial supplier of this resin, which markets under the trade name Stanly. Nylon 46 is an aliphatic polyamide formed by the polycondensation of two monomers, one containing 4 carbon atoms, 1,4-diaminobutane (putrescine), and the other 6 carbon atoms, adipic acid, which give nylon 46 its name. It has a higher melting point than nylon 6 or nylon 66 and mainly used in applications which must withstand high temperatures.

Nylon 46 withstands high loads and stresses at high temperatures and exposure to aggressive environments, and is therefore suitable for under-the-bonnet applications. Typical applications are to be found in the engine and transmission, engine-management, air-inlet, brake, air cooling and electronic systems. Many automotive components have also been produced in nylon 46, because of its excellent creep resistance, toughness and good wear characteristics. As a result of its intrinsic properties nylon 46 has been successfully applied in the following applications and electronics and electrical end-markets.
