Nylon Plastics (Polamides) – AKA PA (such as PA6 & PA66 etc.)

The nylon family of plastics are identified by the number of carbon atoms in the monomers. Where two monomers are involved, the polymer will carry two numbers (e.g. Nylon 66). When just one monomer the polymer will carry one number such as Nylon 6. Crystalline nylons have high tensile strength, flex modulus, impact strength, and abrasive resistance. Several different types of plastic nylon are on the market, the two most widely used being nylon 6 and nylon 6 / 6. General purpose nylon molding materials are available for extrusion, injection molding, blow molding, rotational molding, and (for nylon 6 materials) casting or anionic polymerization. Nylon sheet and film are also marketed.
