Efficiency in focus

AKROMID® T – New PPA based high performance plastics developed by AKRO-PLASTIC

The company AKRO-PLASTIC GmbH, specialist for innovative and application-oriented plastic compounds for more than 20 years has added with the Polyphtalamide AKROMID® T another classical engineering polymer within its product portfolio. The existing product range for substitution of metal die-casting is thus improved.

It’s not only the automotive industry where reduction of weight is growing more and more important due to high energy prices. The high design flexibility as well as extraordinary strength of engineering plastics also offer an economically and technically highly interesting alternative for other industrial sectors, to substitute current metal applications. By eliminating the extra refinishing process often used in metal die casting, the single plastic injection moulding cycle reduces the manufacturing cost of the part. Refinishing, being often the case in metal die casting, is omitted.

 

The new product family AKROMID® T is particularly suitable for the use with high temperature loaded applications, for example under the hood (UTH) of cars or mechanically highly loaded parts in the mechanical engineering sector. The reason is that this material is particularly characterized by a high temperature resistance as well as the lowest moisture absorption of all three PA product lines, originated from AKRO-PLASTIC.

 

In contrast to Polyamide PA 6 or respectively PA 6.6, the wall thickness of parts can be almost halved when developing the application, leading to impressive cost and weight savings.

 

Due to the aromatic semi-crystalline structures of AKROMID® T, highly stable parts even at temperatures of up to +140°C can be realized. Furthermore, the product shows extraordinary creep properties within a broad range of temperature. The very high dimensional stability is of course a consequence of the low moisture absorption. Even after extensive accumulation of water, the strength of a part in AKROMID® T stays at a high level. Due to the high chemical and hydrolysis resistance of the material, also aggressive media such as cleaning - and brake fluids, oils and fats as well as sand and dust can not do any harm to the part.

 

The high temperature resistance of AKROMID® T places it in the area of high performance engineering plastics. Temporarily, parts remain rigid and dimensionally stable even at temperatures of approximately +300°C and permanently at temperatures of up to +200°C. Depending on requirements specification, AKROMID® T acts as an interesting and cost-effective alternative to higher priced high performance plastics.

 

Due to the characteristic and technical features of PPA, AKROMID® T is especially recommended for applications in the automotive sector, in electrical engineering as well as in the heating and sanitary sector.

  

The product family presented in 2009 composes of 30 to 50 % glass-fibre reinforced products. At the K-2010, the following supplements of the AKROMID® T product family are presented:

  • AKROMID T1 GF 30
  • AKROMID T1 GF 40
  • AKROMID T1 GF 50

This product line is especially recommended for applications, requiring high strength and stiffness at temperatures up to 140° C. Furthermore, the chemical resistance has been significantly improved in contrast to PA6 or respectively PA6.6.

  • AKROMID T1 GF 30 9
  • AKROMID T1 GF 40 9
  • AKROMID T1 GF 50 9
  • AKROMID T1 GF 55 9

This product line is especially recommended for applications, requiring high strength and stiffness at temperatures up to 100° C. Furthermore, it is recommended for applications requiring a high quality surface finish.

  • AKROMID T6 GF 30
  • AKROMID T6 GF 40
  • AKROMID T6 GF 50

This product line is especially recommended for applications, requiring high strength and stiffness at temperatures above 150° C. Furthermore, it is recommended for applications requiring a special property balance at temperatures up to 200° C.

AKROMID® T is particularly suitable in the automotive sector, e. g.

  • Thermostatic housing, connectors
  • Central release units
  • Ventilation duct parts (side parts for cooler of air charger, shifter shafts etc.)
  • Highly stressed parts in the passenger compartment (center arm rests etc.)

Furthermore, it is suitable in electrical & electronic engineering, e. g.  

  • Bobbins
  • Bulb- and LED sockets

As well as in the sector industry and applicances, e. g. 

  • Pump manufacturing (functional parts)
