EMS-Grivory Grilamid® 2D 25 W 20 HL X black 9992 PA612-I
Categories: Polymer; Thermoplastic; Nylon (Polyamide PA); Nylon 612 (PA612)

Material Notes: Product Description: Grilamid 2D 25 W 20 HL X black 9992 is a semi-flexible high viscosity, plasticized, high impact and highly heat resistant polyamide 612 (PA612) grade. Unique properties of Grilamid 2D 25 W 20 HL X black 9992 are:
  • High strength, high burst pressure (tube)
  • High heat resistance
  • Significantly lower water absorption compared to standard polyamides
  • Good chemical and hydrolysis resistance
  • Low density
  • Easy processing
Grilamid 2D 25 W 20 HL X black 9992 has been developed for media lines in passenger cars and trucks. Thanks to its excellent heat resistance it is particularly suitable for diesel, air brake, cooling, oil and hydraulic tubes. The product is not recommended for direct permanent contact with gasoline. One particular application is the use as outer layer of multilayer ECOSYS coolant tubes. ECOSYS (EMS Cooling System) is the designation for tube solutions developed by EMS-GRIVORY for automotive heating and cooling systems.
