Akro-Plastic Akromid® T1 GF 50 (3101) PPA Dry, 50% Glass Filled
Categories: Polymer; Thermoplastic; Polyphthalamide (PPA); Polyphthalamide (PPA), 50% Glass Fiber Reinforced

Material Notes: AKROMID® T is characterized primarily by high heat resistance and the lowest moisture absorption of the manufacturer's PA grades, making it particularly suited in the automotive sector for high-temperature applications in the engine compartment and in machine building for components subjected to high mechanical loads. It easily maintains its high initial stability even at temperatures of up to 140 °C and still exhibits excellent creep behavior. This high dimensional stability is further enhanced by the product’s low moisture absorption. Another advantage over PA 6 or PA 6.6 is the improved chemical resistance and high resistance to hydrolytic degradation. These properties – along with the aforementioned advantages in terms of mechanical loading – make the material useful for difficult applications in industrial pumps and fluid filters. Its low water absorption over extended periods is yet another advantage. By modifying the base grades, the material can be suitable for applications requiring a high quality surface finish.

Applications:

    Automotive Sector:
  • Cooling system (thermostat housing, connectors, etc.)
  • Parts in the oil circuit (tensioner bases, etc.)
  • Parts in the brake system (valve bodies, etc.)
  • Clutch components (central clutch release bearing, etc.)
  • Air ducting parts (side pieces for charge-air coolers, control shafts, etc.)
  • Parts subjected to high loads in the interior (centre armrest, etc.)
    Electrical Engineering:
  • Mobile telephone parts (chip carrier, etc.)
  • Coil formers
  • Motor parts (brush holders, etc.)
  • Plugs and connectors
  • Bulb and LED sockets
    Industry and Household:
  • Heating systems (fan housings, etc.)
  • Components for coffee machines (grades compliant with KTW- German recommendation for polymers in drinking-water systems)
  • Water counters and water filters (KTW-compliant, hot water)
  • Pump systems (misc. functional parts)
