Wanfeng New Material Technology Co., Ltd. specializes in the production of high-performance Magnesium Oxide (MgO) for rubber applications.

Our high-purity, high-activity MgO is specially suitable for NBR (Nitrile Butadiene Rubber) formulations, providing excellent acid absorption, processing stability and vulcanization performance.

Why MgO is Used in NBR?

In NBR rubber compounds, Magnesium Oxide can function as an acid acceptor, curing-system activator and processing aid. It helps neutralize acidic substances generated during processing and vulcanization, while contributing to the stability and physical properties of the final rubber compound.

Key Advantages

• High purity – helps minimize impurities that may affect rubber performance.

• High activity – provides efficient acid absorption and reaction performance.

• Excellent dispersion – suitable for uniform incorporation into NBR compounds.

• Good processing stability – helps maintain stable processing and vulcanization conditions.

• Improved compound stability – helps control acidic substances during vulcanization.

• Suitable for various NBR applications – including oil-resistant seals, gaskets, hoses, O-rings and other technical rubber products.

Recommended Grade: SH-150X

Our SH-150X is a high-purity, high-activity Magnesium Oxide with a reaction activity above 150. It is particularly suitable for demanding NBR rubber formulations where high activity and consistent quality are required.

We can also provide different MgO grades according to customers' requirements, including customized specifications for activity, purity, particle size and application performance.

If you are currently using MgO in NBR rubber, we would be glad to recommend a suitable grade and provide a sample for your testing.
