UCM Tateho Quality Tubular Cartridge Heaters Heating Element Middle Temperature Magnesium Powder

SD-6 Series:Including SD-6 series MgO products are moisture-proof magnesium oxide, ?which are mainly used for non-air heating elements (Such as copper tubes, aluminum tubes ,Bundy tubes or stainless steel tubes etc. with stronger convection and contact thermal transfer), and can satisfy different requirement. It is high moisture-proof, simply sealing is available. We suggest to dry the heating elements at 200?-350? before sealing.SD-99Series:Including SD-99 series MgO products are moisture-proof and high temperature resistant magnesium oxide, ?which are mainly used for air heating elements with different wattage loading, isn’t suitable for high-heat treatment(such as 1050? annealing),it has high moisture proof property, simply sealing is available.
