There is no denying that the use of filler masterbatch plays an indispensable part in the plastic industry. Among various types of fillers such as calcium carbonate filler, talc filler,… BaSO4 transparent filler easily stands out thanks to its amazing advantages. So, what exactly is BaSO4 filler and how does it benefit our plastic industry? Let’s find out in the article below!

According to some research, global plastic filler masterbatch market size is projected to reach USD 422.1 million by 2026, from USD 364 million in 2020, at a CAGR of 2.5% during 2020-2026. This figure illustrated the considerable increase of filler masterbatch consumption. In which, BaSO4 filler (also known as transparent filler masterbatch) is one of the most vital sectors. 

How does BaSO4 transparent filler masterbatch benefit the plastic industry?

As the name suggests, calcium carbonate filler takes CaCO3 powder as the main component while BaSO4 transparent filler 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 filler, 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.

Besides, BaSO4 filler also offers end-products several benefits such as great dispersion, good light durability,… making it an appropriate choice for outdoor uses. Moreover, transparent filler also enhances the stiffness, chemical resistance of end-products as well as reducing their electrical properties.

Another reason for the popularity of BaSO4 transparent filler is the environmental friendliness of this material. BaSO4 barely causes any harmful effects to the environment and is also safe for human beings.

4 common applications of BaSO4 transparent filler in plastic industry

Thanks to its outstanding advantages, BaSO4 filler is widely used in various applications, especially in the packaging industry. Some typical uses of this material are listed below.

Agricultural films

Green house films

It is not exaggerated to say that BaSO4 transparent filler is a vital component of this type of film. Basically, agricultural films have certain strict requirements regarding filler masterbatch, including high transparency, good weather resistance,… to ensure they are able to prevent harmful impacts of sunlights on plants while allowing the flow of photosynthesis. Hence, the use of BaSO4 filler can meet all of those criteria since it has great transparency and good UV resistance ability. Currently, transparent filler is widely used in greenhouse film, crop forcing film, silage film, silage stretch film,…

Food packaging films

Food packaging film

F&B industry is another important end-use market of BaSO4 transparent filler. Its common applications include food wrapper, waste bags, rolled bags,… Not only improving the brightness and transparency of the films, this material is also completely harmless to human health compared with fossil resins, making it an ideal choice for food containing uses.

Retail industry

Shopping bags

As a huge amount of packaging film consumption goes to the retail industry, BaSO4 transparent filler is also a vital material to this field. Its application improves the thermal resistance, anti slipping ability and printability of the film. Plus, compared to NaSO4 filler, BaSO4 filler is anti-moisture, which makes it more durable in case of water condensation on the surface. 

Household appliances and other injection moulding products

Injection moulding products

An outstanding advantage of BaSO4 transparent filler is it works effectively not only in blown film products, but also in several injection moulding products such as small parts of household appliances, bottles, cans,… By adding BaSO4 into formular, these end-products are provided with great stiffness, anti corrosion ability, anti slipping ability and printability. Furthermore, transparent filler also assists in reducing the shrinkage as well as helping end-products stay well in shape.

All things considered, BaSO4 filler is an effective type of material for various industries to enhance their end-products’ quality and protect end-users’ health by cutting down on fossil resins. 

Things to note when using BaSO4 transparent filler

Useful as it is, BaSO4 filler 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 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 as a cost-effective material solution. 

Of course, the firms can save the 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:

Advantages Disadvantages

Good dispersion
Good weather resistance

Advantages and disadvantages of BaSO4 filler

Therefore, unless a specifically 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 filler still gets a vote regarding the affordability compared with the use of pure fossil resin. Hence, for the best performance, BaSO4 transparent filler is still preferred by many manufacturers
