Product Description
Spare parts&fitting for tubular heater
SD-8 Series:
Including SD-8(Grade A),SD-99A(Grade B)
series MgO products are light silicone or no silicone treatment MgO, including Grade A,Grade B,Grade C,Grade D, which can be used for air heating elements with different wattage loading . It can bear high-heat treatment( such as 1050ºC annealing),but it can't be moisture-proof, and need to be sealed immediately and effectively.
