Light Burned Magnesia for Rubber Industry from China
Light burned magnesia for the rubber industry is a caustic magnesia produced by calcining magnesite at 700-1000°C, giving it high reactivity as an acid acceptor in rubber vulcanization. It is classified under tariff item 2519.90.00 as 'other' magnesium oxide, since it is not fused or dead-burned and the low-temperature calcination is within Chapter 25 Note 1.
