What is plastic CaCO3 Filler Masterbatch?

Plastic fillers are particles added to resin with the purposes of improving specific properties (tensile strength, toughness, heat resistance, color, clarity, etc), reducing production cost, or both. More than 53 million tons of plastic fillers, with the value of approximately 18 billion US dollars, are used every year in various fields such as plastics, rubber, adhesives, paper, etc. Up to 70% of plastic products consist of plastic filler, a surprisingly high number.

Plastic filler CaCO3 Filler Masterbatch – an important material in plastic industry

In this article, MASKA GLOBAL will introduce types of plastic filler, its application in the plastic industry and where you can get plastic filler for your production.

1. What is types of calcium carbonate CaCO3?

1.1 Calcium carbonate (CaCO3)

Calcium carbonate (CaCO3) plastic filler is the most widely used filler in the plastic industry, which allows cost reduction and improved mechanical properties. These additions in your products can also improve molding productivity by decreasing cooling rate.

CaCO3 Filler masterbatch – the most used application of Calcium carbonate in plastic industry

The CaCO3 in the filler is found in sedimentary rocks (chalk, limestone), marbles and minerals (dolomite). Especially in Vietnam, calcium carbonate is made of natural mineral calcite with high pure over 99 %, high whiteness > 96 %, treatment surface by additive and use perfect technology, which helps to improve some properties such as: whiteness, hardness, strength.

Plastic filler can have a large percentage of calcium carbonate in its composition. Calcium carbonate powder accounts for 97% of composition and will bring for white/opaque products more whiteness. With smaller percent, calcium carbonate powder can be used for color products. In addition, it brings for final plastic products a brighter and glossy surface.

1.2 Talc plastic filler Masterbatch

Talc filler consists of talc powder, carrier resin (PP, PE, etc) and other additives. Talc filler is used in resin casting to reduce cost, shrinkage & heat generated by resin curing. The more filler added to resin the stiffer the mix. In the plastic industry it is used for packaging and food application due to its long-term thermal stability. It also improves tensile strength, translucent, anti blocking effect, imparts paper like feel, crackling sound

1.3 Barium sulfate plastic filler

Barium sulfate (BaSO4) plastic filler is used for the purpose of increasing the density of the polymer in vibrational mass damping applications. Barium sulfate has become a new plastic material as one of the functional modified materials with excellent performance.

Barium sulfate plastic filler

Barium sulfate plastic filler is used widely for improving the chemical resistance of plastic products, improving the appearance of products and other characteristics, in many fields such as household appliances shell, machinery, auto parts, air conditioning panels.

Barium sulfate plastic filler can also increase the proportion of plastic products, improve the wear resistance of plastic, anti-aging, increase the gloss, etc., to expand the application of plastic products.

1.4 Sodium sulfate plastic filler

The most important component of sodium sulfate plastic filler is obviously sodium sulfate, whose chemical formula is Na2SO4. Sodium sulfate plastic filler has various benefits such as increasing the transparency of products (so that this type is also called as transparent masterbatch), improving the surface gloss of the end-products, reducing the production cost and improving the production efficiency, reducing heat release from burning and so on. This type of plastic filler is also a friendly-environment functional masterbatch.

2. Where to buy plastic filler?

The factors which make a good supplier are quality/reliability, speed/flexibility, value for money, strong service/clear communication and financial security.
