Why should Barium Sulfate Precipitated be added in plastic modification?
Application of Barium Sulfate Precipitated: Wide Plastics generally refer to the plastics with large production, wide-range in application, good formability and affordable price, such as PE、PPR、PF and so on. Many of the products people use in their daily lives are made of these wide plastics.
Wide Plastics has the advantages of good formability and affordable price, but its disadvantages such as easy aging, easy deformation and so on bring a lot of inconvenience to users. In order to overcome these shortcomings, it can be improved by modifibation and adding Barium Sulfate Precipitated to improve and meet the needs of practical applications.
The unique and excellent properties of Barium Sulfate Precipitated make it widely used and become one of the new functional modification materials for plastic products. Barium Sulfate Precipitated can improve the chemical corrosion resistance, heat resistance and appearance of plastic products.
Application of Barium Sulfate Precipitated
So in addition to these characteristics, what specific role did Barium Sulfate Precipitated play in the process of plastic modification?
Improve the Rigidity of plastics
Generally, the rigidity of plastics is poor. For example, the Flexural Modulus of pure PP is about 1000MPa, which is far from satisfying the application requirements of some parts. After 20% increase of Barium Sulfate Precipitated, the Flexural Modulus can reach more than 2000MPa, which shows that Barium Sulfate Precipitated has a significant stiffening effect on it.
Improve the Surface hardness of plastics
Usually the Surface hardness of plastics is low, the appearance is easy to scratch, affect the appearance, and then affect its Exterior function and decoration. The hardness of inorganic filler is higher than that of plastic, the increase of inorganic filler(such as Barium Sulfate Precipitated) can greatly improve the appearance of plastic hardness.
Improve the Dimensional stability of plastic products and components
Shortening caused by crystallization of some plastic is big, resulting in a large shortening rate of its products, they are also easy to deform after coming out of the mold, and the dimension is not stable. However, the increase of filler can greatly reduce the shortening rate of plastic, and then improve the dimension stability of plastic products and components.
Improve the Processability of plastics
Some fillers can improve the processability of plastics, such as barium sulfate, glass beads, etc., can improve the fluidity of resin, and then can improve its processability.
Improve the Strength of plastics
The tensile strength of Wide plastics is not high. Within the proper range of filling, the tensile strength and tortuous strength of plastics can be enhanced after increasing the inorganic filler, and then improve the engineering usability of plastics.
Improve the Added value of plastics
Some fillers can give plastic some functions, such as the antistatic function and printing function of PP can be improved by adding Talc and Calcium carbonate powder; the insulation function of plastics can be improved by adding insulating glass beads; the thermal and electrical conductivity of plastics can be improved by adding metal particles.
The Application of Barium Sulfate Precipitated: The unique and excellent properties of Barium Sulfate Precipitated make it widely used. It has made remarkable achievements in the plastic industry and become one of the important and indispensable functional materials in the plastic industry.
