How does magnesium oxide improve the processing safety and stability of rubber?

Magnesium oxide enhances the processing safety and stability of rubber by increasing the vulcanization rate and catalytic effect.

                    Magnesium oxide enhances the processing safety and stability of rubber by increasing the vulcanization rate and catalytic effect.

                    The specific functions of magnesium oxide in rubber processing include:

                    Improving vulcanization rate:Magnesium oxide can significantly accelerate the vulcanization rate of rubber,making the entire vulcanization process more efficient and helping to improve production efficiency.

                    Play a catalytic role:At lower temperatures,magnesium oxide can play a catalytic role,which helps reduce energy consumption and also reduces rubber aging problems that may occur due to high temperatures.

                    Enhanced thermal stability:After adding magnesium oxide,the thermal stability of vulcanized rubber is enhanced,which is an important performance indicator for the use of rubber products in high-temperature environments.

                    Improving scorching performance:Magnesium oxide can effectively suppress scorching phenomenon,prevent premature curing,and ensure the quality and stability of rubber products.

                    Improving physical and mechanical properties:In some rubbers,such as chloroprene rubber,the addition of active magnesium oxide can enhance their physical and mechanical properties,especially the characteristic of reducing permanent deformation,which is crucial for maintaining the shape and structural integrity of rubber products.

                    Acid absorption effect:Magnesium oxide has a good acid absorption effect,which can absorb acidic substances generated during the vulcanization process,such as hydrogen fluoride,protecting metal parts from corrosion and also protecting the performance of rubber itself.

                    In summary,magnesium oxide effectively improves the processing safety and stability of rubber by increasing vulcanization rate,exerting catalytic effect,enhancing thermal stability,improving coking performance,enhancing physical and mechanical properties,and acid absorption effect.These characteristics make magnesium oxide a very important additive in the rubber industry.
