Product Details

Low Temperature Electrical grade magnesia powder (LTM) is moisture-proof magnesium oxide,used for non-air heating elements(such as copper tubes,aluminum tubes or stainless steel tubes etc. With stronger convection and contact thermal transfer), which is high moisture-proof,simply sealing is available. We suggest to dry the heating elements at 200°C-350°C before sealing.
