Polyamide-Imide PAI

Solvay Advanced Polymers is also the world s only producer of polyamide-imide with its Torlon product range. [Pg.32]

Polyamide-imide is produced from a reaction between trimellitic, anhydride, and various diamines. It has a high melt viscosity and is reactive in the melt state. Accordingly, it is not possible to reduee viscosity by raising temperature. Injeetion moulding requires heavy duty, high rate maehines, preferably using hydraulie accmnulators. It is also possible to compression mould and extmde into stock shapes. [Pg.32]

PAI offers similar outstanding performance in extreme environments to thermosets. These resins have exceptional strength at high temperature with excellent resistance to creep, wear and chemicals, including organic solvents. [Pg.32]

PAI is also used in coating applications, due to its outstanding surface adhesion to many different materials including metals and polytetrafluoroethylene. [Pg.32]

PAI is mainly used in injection moulding applications and has been replacing metal in a range of automotive and electrical electronics applications in recent years. Examples include [Pg.32]

Polyamide Imides. Polyamide imides (PAIs) are formed from the condensation of trimellitic anhydride and aromatic diamines (33). The polymer is called amide—imide because the polymer chain comprises amide linkages alternating with imide linkages, with the general chemical stmcture ... [Pg.40]

Matrix materials for commercial composites are mainly liquid thermosetting resins such as polyesters, vinyl esters, epoxy resins, and bismaleimide resins. Thermoplastic composites are made from polyamides, polyether ether ketone (PEEK), polyphenylene sulfide (PPS), polysulfone, polyetherim-ide (PEI), and polyamide-imide (PAI). [Pg.207]

Other than the polymeric additives mentioned earlier, polymers such as polyetherimide (PEI) [25], polyamide-imide (PAI) [27,35], PSR [26], PSF [36], and polycarbonate (PC) [37] are also proposed over the past few years as potential additives in UF membrane fabrication. The difference between these polymers and water-soluble additives, for example, PEG and PVP, is that they can be used either as the main membrane-forming material (by dissolving in an appropriate solvent) or as an additive to explore their...

The engineering polymers that have already reached maturity consist of the Nylons (PA), polycarbonate (PC), acetal (POM), polyesters (PBT and PET) and Noryl (PPO). Their relative price is aroxmd 3. Including very novel polymers, a prestigious high priced group consists of the advanced engineering polymers (high performance) polysulfone (PSU), polyphenylene-sulfide (PPS), fluoroethylenes (PTFE and its derivatives), polyamide-imide (PAI), polyether-imide (PEI), polyethersulfone (PES), polyether-ether-ketone (PEEK), aromatic polyesters and polyamides, polyarylates and liquid-crystal-polymers (LCP).

Polyamide-imide (PAI) is a high-temperature amorphous thermoplastic that has been available since the 1970s under the trade name of Torlon. PAI can be produced from the reaction of trimeUitic trichloride with methylenedianiline as shown in Fig. 2.11. [Pg.69]

The two typical example of copolyamide type of aramid fibres are Technora (Teijin) and Kermel (Kermel) fibres. Technora fibres is produced from reactions between a mixture of p-phenylenediamine (PPD) and 3,4 -diaminodiphenylether (3,4 -ODA) with terephthaloyl chloride (TC1), and Kermel fibre is a polyamide imide (PAI) fibre, which has the advantage of having little shrinkage in hot water (= 0%) and hot air (0.2%). ...

This is an engineering plastic designed for thermal/electrical applications requiring high dimensional stability. This material exhibits superior electrical and mechanical performance at continuous use temperatures ranging from -60 to 260 °C. Pyropel HDT polyamide-imide (PAI) produced by Albany International [35] has enhanced properties without the need for post-curing. [Pg.19]
