Synthetic polyamides are commonly used in textiles, automotive industry, carpets, kitchen utensils and sportswear due to their high durability and strength. The transportation manufacturing industry is the major consumer, accounting for 35% of polyamide (PA) consumption. [2]
Polyamide-imide resin is hygroscopic, and picks up ambient moisture. Before processing the resin, drying is required to avoid brittle parts, foaming, and other molding problems. The resin must be dried to a moisture content of 500 ppm or less. A desiccant dryer capable of maintaining a dew point of −40 °F (−40 °C) is recommended. If ...
A wide range of polymers are now produced in glass-filled varieties, including polyamide (Nylon), acetal homopolymers and copolymers, polyester, polyphenylene oxide (PPO / Noryl), polycarbonate, polyethersulphone [4] Bulk moulding compound is a pre-mixed material of resin and fibres supplied for moulding. Some are thermoplastic or thermosetting ...
Nylon 66 (loosely written nylon 6-6, nylon 6/6, nylon 6,6, or nylon 6:6) is a type of polyamide or nylon. It, and nylon 6 , are the two most common for textile and plastic industries. Nylon 66 is made of two monomers each containing 6 carbon atoms, hexamethylenediamine and adipic acid , which give nylon 66 its name. [ 1 ]
Repeating unit of polyphthalamide. Polyphthalamide (aka.PPA, [1] High Performance Polyamide) is a subset of thermoplastic synthetic resins in the polyamide family defined as when 55% or more moles of the carboxylic acid portion of the repeating unit in the polymer chain is composed of a combination of terephthalic (TPA) and isophthalic (IPA) acids. [2]
Polyimide is used to coat optical fibers for medical or high temperature applications. [15] An additional use of polyimide resin is as an insulating and passivation [16] layer in the manufacture of Integrated circuits and MEMS chips. The polyimide layers have good mechanical elongation and tensile strength, which also helps the adhesion between ...

Envalior (formerly DSM) is the only commercial supplier of this resin, which markets under the trade name Stanyl. [ 1 ] [ 2 ] 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.
