3 Comparative tables of compounds .. Overview of PA 612 compounds and their applicationsEvonik s High Performance Polymers Business Line manufactures a range of polyamide 612 (PA 612) compounds, which are supplied under the registered trademark Vestamid D. PA 612 is the polycondensation product of 1,6-hexamethylene diamine and 1,12-dodecanedioic acid (1,10-decane dicarboxylic acid):The carbonamide groups (-CO-NH-) of the polyamides form hydrogen bridge bonds between the chains of the mac-romolecules, thereby substantially pro-moting crystallinity and increasing their strength, melting point, resistance to chemicals, and even water absorption.

4 This is characteristic of all semi-crystal-line polyamidesPolyamide 12 has the lowest carbon-amide group concentration of all com-mercially available polyamides, giving it the lowest moisture absorption and largest dimensional stability of parts in changing conditions of ambient humid-ity. In polyamide 612, the concentration is slightly higher but still well below that of polyamide 6 or polyamide 66. Molded parts made of polyamide 612 consequently share, nearly unchanged, the same characteristics that are prized in PA 12 molded parts: high impact strength very good resistance to greases, oils, fuels, hydraulic fl uids, water, alkalis, and saline solutions very good stress cracking resistance, even when subjected to chemical at-tack and when used to cover metal parts low coeffi cients of sliding friction and high abrasion resistance, even when running dryIts advantages over PA 12 exhibit in the heat defl ection temperature (melting point nearly 40 C higher)

5 Tensile and fl exural strength outstanding recovery at high wet strengthThe PA 612 compounds of theVESTAMID D series consequently repre-sent specialty products that complement the comprehensive selection of PA 12 compounds of the Vestamid L series. Like all high-performance plastics of the High Performance Polymers Business Unit, Vestamid compounds satisfy the highest quality standards. Our sys-tem for quality assurance is certifi ed ac-cording to ISO 9001:2008. In several audits conducted by our customers, this quality management system received excellent (CH2)6-NH2 + HOOC-(CH2)10-COOH [NH-(CH2)6-NH-CO-(CH2)10-CO] PA 612 compounds and their applicationsThe PA 612 product line logically com-plements the comprehensive off ering of our PA 12 compounds.

NomenclatureVESTAMID compounds are divided into sales and development products. The composition and manufacturing methods of sales products have been established on the basis of extensive experience and wide acceptance, and these products have a systematic no-menclature.

9 In the case of development products, formulations are still subject to change so that they can be optimized for particular applications. Sales productsStandard sales products in theVESTAMID 612 series are named with the letter D, identifying dodecanedioic acid as the monomer base. For unfi lled standard products, the next two digits correspond to one tenth of the average viscosity number (J value) measured in m-cresol in accordance with ISO 307. The standard also permits the measure-ment to take place in 96-percent sulfu-ric acid instead of m-cresol. Although the two values diff er, they correlate strongly* (see Figure).

10 We do not pro-vide melt fl ow rates (MFR, MVR), be-cause polyamides have to be viewed as living polymers under the specifi ed test conditions. Even minimum water contents in the resins will cause the melt fl ow rates to become highly varia-ble and non-reproducible without af-fecting the solution viscosity. In gen-eral, the higher the J value (and the two digits in the product name), the higher the molecular weight, melt viscosity, and impact strength can be expectedto fi nal component of the name is the color. Example: Vestamid D16 natural color.*) In the quality test, we only measure the solution vis-cosity in m-creosolDevelopment productsDevelopment products are created for particular applications.
