Murtfeldt Murdopol® Nylon 12
Categories:	Polymer; Thermoplastic; Nylon (Polyamide PA); Nylon 12 (PA12); Nylon 12, Cast
Material Notes:	Murdopol® has extremely high shock and impact resistance characteristics and good emergency running characteristics thanks to its high wear resistance. The main advantage of this material is its ability to create firm plastic/metal connections. Special Properties: • Good shock and impact resistance • Low residual stress • Metal core surrounded by cast plastic available • Good damping and vibration behavior • Lowest moisture absorption of all polyamides • Good resistance to chemicals • Dimensionally stable Information provided by Murtfeldt Kunststoffe GmbH & Co. KG.
Key Words:	PA 12-G
