The use of magnesium oxide in plastic processing

The main uses of magnesium oxide in plastic processing are as a plasticizer,stabilizer,and flame retardant,which can improve the heat resistance,UV resistance,and flame retardancy of plastic products.These applications utilize the high dispersibility,non-toxic,odorless,and environmentally friendly properties of magnesium oxide.

               The main uses of magnesium oxide in plastic processing are as a plasticizer,stabilizer,and flame retardant,which can improve the heat resistance,UV resistance,and flame retardancy of plastic products.These applications utilize the high dispersibility,non-toxic,odorless,and environmentally friendly properties of magnesium oxide.The following will provide a detailed introduction to the specific uses and functions of magnesium oxide in plastic processing:

Plasticizer

               Improving processing performance:Magnesium oxide enhances the plasticity and flowability of plastics,making them easier to process and shape.This effect helps to improve production efficiency and reduce energy consumption during the processing.

               Promoting plasticization:During the plasticization process,magnesium oxide can reduce the viscosity of the melt,making the plastic easier to shape,thereby accelerating production speed and reducing energy consumption.

stabilizer

               Thermal stability effect:Magnesium oxide can improve the thermal stability of plastics and prevent thermal decomposition during high-temperature processing or use.This is particularly important for plastic products that need to withstand high temperature environments.

               Light stabilization effect:Magnesium oxide has the ability to absorb ultraviolet radiation,which can protect plastics from ultraviolet radiation and extend their service life.This is particularly important for plastic products that are exposed outdoors.

Flame retardant

               Improving flame retardancy:Magnesium oxide,as an effective flame retardant,can form a refractory layer during plastic combustion,isolating oxygen and heat,and slowing down the combustion rate.This performance is crucial for improving the safety of plastic products.

               Environmental characteristics:Compared with traditional phosphorus or halogen organic flame retardants,magnesium oxide is non-toxic,odorless,and has a small amount of additives,making it an ideal additive for developing environmentally friendly flame retardant plastics.

Thermal conductive filler

               Improving thermal conductivity:Magnesium oxide specifically designed for thermal conductive plastics can significantly increase the thermal conductivity of plastics,reaching 2W/(m.K)or even higher.This makes plastic products more efficient in heat dissipation,suitable for fields such as LED lighting,automobiles,heating/cooling/refrigeration,etc.

               Maintaining mechanical properties and electrical insulation:While improving thermal conductivity,plastic products filled with magnesium oxide can still maintain good mechanical properties and certain electrical insulation properties.This balance enables plastic products to perform well in various applications.

Application of ABS resin

               Control color difference:In ABS resin,the color of magnesium oxide has a significant impact on the color difference of the final product.The odorless,tasteless,and good dispersibility of magnesium oxide make it a key factor in controlling color difference in plastic products.

               Technical requirements:The resin's requirements for magnesium oxide include high content(≥93-95%),low heavy metal content,large volume,good whiteness,and purity.These characteristics ensure the efficient application of magnesium oxide in plastic processing.

               In summary,magnesium oxide has a wide and diverse range of applications in plastic processing,from improving processing performance,enhancing thermal stability and flame retardancy to improving thermal conductivity and controlling color difference,all of which significantly enhance the comprehensive performance of plastic products.In the future,with the continuous advancement of technology and the increasing market demand,the role of magnesium oxide in the field of plastic processing will become more important and widespread.
