EMS-Grivory Grilamid® XE 4071 nat PA612-I
Categories:	Polymer; Thermoplastic; Nylon (Polyamide PA); Nylon 612 (PA612)
Material Notes:	Product description: Grilamid XE 4071 NATURAL is an unreinforced impact modified high viscosity polyamide 612 (PA612) extrusion grade with superior hydrolysis and heat resistance. Compared to standard Grilamid grades XE 4071 NATURAL exhibits an improved resistance when exposed to water/glycol mixtures as found in automotive coolant fluids. Furthermore it is highly resistant to heat, automotive fluids and chemicals in general. Grilamid XE 4071 NATURAL has been developed for use in the cooling / heating system of vehicles. One particular application is the use as outer layer material of the ECOSYS tube solution. Grilamid XE 4071 NATURAL is suitable for other demanding automotive tubings too. ECOSYS (= EMS Cooling System) is the designation of flexible partially corrugated multilayer tubes developed by EMSGRIVORY for automotive heating and cooling systems.
