barium sulfate
BaSO4 masterbatch is made of barium sulfate, which is then mixed with suitable plastic resin and other additives. This difference results in the specific properties and applications of each type of filler.
For example, CaCO3 filler is normally more opaque than BaSO4 MB, thus it is less preferred in packaging applications that require a high level of transparency. As a result, the name transparent filler masterbatch comes as an identity of this material.
Applications
BaSO4 is widely used in various applications, especially in the packaging industry. Some typical uses of this material are listed belowand applications of each type of filler.
Agriculture films,Food packaging films,Retail industry, Household appliances and other injection moulding products
Features
Environmental friendliness
BaSO4 barely causes any harmful effects on the environment and is also safe for human beings.
Chemical Resistance
the transparent MB also enhances the stiffnes, and chemical resistance of end-products
Electrical Properties
the transparent MB also resistance of end-products as well as reducing their electrical properties.
Things to note when using BaSO4 transparent MB
Useful as it is, BaSO4 MB still has a big disadvantage that more or less bothers plastic enterprises. In comparison with other types of filler masterbatches such as talc filler or calcium carbonate (CaCO3) filler, it is relatively more expensive. Generally, the higher the loading rate of barium sulfate powder is applied, the more costly it gets. That definitely makes it less attractive than the others since for most plastic firms, filler masterbatch is considered a cost-effective material solution.
Of course, the firms can save expenses by cutting down on the BaSO4 powder consumption. However, it will decrease the transparency of the end-products, which we all know is not allowed. The pros and cons of using BaSO4 transparent filler are listed in the table below:
Therefore, unless a specific high level of transparency is required for end-products, plastic enterprises are likely to choose PE filler masterbatch or PP filler masterbatch for the suitable functionalities and reasonable price. However, one thing to note is that BaSO4 MB still gets a vote regarding affordability compared with the use of pure fossil resin. Hence, for the best performance, BaSO4 transparent MB is still preferred by many manufacturers.
