Note:
Some suppliers mention the Max Working Temp is 180°C for NMP-1412, and 160°C for other grades, that is the result from the different test method.Different Temp Coefficient for Br and Hci with other suppliers, that depend on the different test method and equipments.Tianjin Nibboh Magnets Co., Ltd
