Introduction

White filler masterbatch, accounting for an approximately USD 350 million share in ,  is one of the leading types of filler masterbatch. This is likely because not only reduces environmental impact and cuts costs, but it also helps the final product achieve the aesthetic purpose while still fully retaining the durable characteristics of plastic.
All of them are not the same, let alone their distinction can fluctuate very differently to every need. This guide will lead you to five common types of white filler masterbatch, including the advantages, the diverse applications across various industries.

1. Types of White Filler Masterbatch

1.1. Sodium Sulfate (Na2SO4)

Enhance product appeal and functionality with white filler masterbatch solutions

2. Benefits of Using White Filler Masterbatch

Achieve optimal opacity without sacrificing budget with white filler masterbatch.

So, why white filler masterbatch. They didn't put themselves here for no reason. As we know, besides the whitening main mission of these fillers, they have already done some side quests that we may not even have noticed.

• Enhanced Opacity:

The white filler plays its most powerful role in masking the natural opaque color of the pure resin, providing a perfect bright white coating to the final product.
This uniform and stable white coating is created most effectively using premium titanium dioxide (TiO2) combined with other additives. Applications such as packaging materials and consumer goods, where a pure, brilliant white appearance is sought, will especially benefit from this.

• Cost Reduction: 
  

Compared to stockpiling large amounts of virgin plastic, incorporating white fillers can optimize the selection of derivative materials, thereby optimizing production costs.
One of the common white fillers, CaCO3 stone powder is a high-quality resource and large reserves around the world. Therefore, this stable supply chain minimizes long-term logistical cost pressures, eventually reducing final costs and increasing competitiveness in the market.

• Improved Properties: 
  

Overall, they help increase the mechanical properties of the product: Increase hardness, flexibility, reduce shrinkage rate. Also, the uniform color distribution is important to all plastic products. By precisely dosing and dispersing white masterbatch in the base polymer, manufacturers can easily remove the possibility of color changes during the manufacturing process.
In addition, the ability to enable even heat distribution for film blowing and spinning products helps reduce bubbles on the plastic surface throughout the production process, limiting minor faux from happening. 

• Embracing Creativity and Versatility
  

External factors are always the most unpredictable enemies for outdoor plastic products, so requirements for these products are always changing.
And in this aspect, white fillers can be fluctuated easily. The white filler composition can be easily adjusted due to its high compatibility with a variety of plastic substrates. For example, the product is supplemented with a white filler containing titanium dioxide particles, which provides excellent UV protection, helping the overall longevity and integrity of the product when continuously exposed to the sun.

White filler masterbatch offers a balanced solution between aesthetics, functionality, and efficiency

When talking about the application of plastic, the first thing definitely is the packaging field. Not only does it make the final product aesthetically pleasing, but it also enhances packaging functionality and perfects high quality and performance.

• Improved Food Safety: Some white fillers, such as titanium dioxide, can limit UV rays, forming a shield to protect foods sensitive to UV rays. Together with some additives such as Hindered Amine Light Stabilizers (HALS), UV Absorbers (benzotriazoles, benzophenones), Antioxidants, Nano-Clay, UV resistance can be multiplied.
  
• Enhanced Product Visibility: White filler helps the packaging take on an opaque white layer, giving the packaging a neat and professional appearance, allowing branding elements and product information on the packaging to take center stage.
  
• Cost-Effective Opacity: The additives in white masterbatch typically less expensive than pure resin. Additionally, the filler masterbatch is pre-dispersed, which means that the filler particles are evenly distributed in the carrier resin. This avoids the need for additional processing processes such as mixing and distributing coarse fillers in virgin resin throughout the manufacturing process.
  

Example:

• White milk bottles and food containers
• Opaque pouches for dry goods (pasta, rice, snacks)
• Pharmaceutical and medical packaging (where product visibility is not essential)
  

3.2. Textile

The range of fields with products made from calcium carbonate nonwoven fabrics is very large, from medical and personal care to hygiene, geotextiles (support with filtration, separation, and reinforcement, used in civil engineering applications like drainage and erosion control).

• Reduces the gloss effect, enhancing the covering ability of the fabric structure
• Creates a natural white layer, improving the fabric's covering power
• Enhances thermal conductivity and mechanical strength

3.3. Construction 

White fillers can help make building more efficient over time:

• Reduced Shrinkage: In some cases, specific fillers can contribute to reducing the shrinkage rate of plastics during processing. This will improve dimensional accuracy and minimize product warping, potentially leading to more functionalities.
  
• Weather Resistant: White fillers can provide some additional UV protection, potentially contributing to the overall weather resistance of a product. This can help slow down the degradation of plastics caused by sunlight exposure in outdoor applications.

• White PVC pipes for plumbing and drainage systems
• White window and door profiles made of uPVC (unplasticized polyvinyl chloride)
• Opaque white roofing sheets made of materials like PVC or polypropylene
