EMS-Grivory Grivory® XE 4208 black 9992 PA612-I

Product description: Grilamid XE 4208 black 9992 is a semiflexible high viscosity, plasticized, high impact and highly heat resistant polyamide 612 (PA612) extrusion grade. Unique properties of Grilamid XE 4208 black 9992 are:

• High strength, high burst pressure in tube form
• High heat resistance
• Significantly lower water absorption compared to standard polyamides
• Good chemical and hydrolysis resistance
• Zincchloride resistance
• Low density
• Easy processing

Application examples: Grilamid XE 4208 black 9992 was 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 coextruded ECOSYS tubes. ECOSYS (EMS Cooling System) is the designation of multi-layered tubes developed by EMS-GRIVORY for automotive heating and cooling systems.
