An Additive Masterbatches Supplier in the Philippines That Can Provide You With the Items You Need


Masterbatches are often used by manufacturers to add color, texture, glossiness, and other properties to plastics. They can either be a concentrated mixture of pigments and/or additives that are compressed during a high-heat process into a carrier resin that is eventually cooled and cut into granular shapes. Instead of buying a fully compounded material, businesses purchase these non-food ingredients since they are much more economical.

At Wills International Sales Corporation, our team is dedicated to providing clients with high-quality materials. We are an additive masterbatches supplier in the Philippines, and we take great pride in having helped numerous companies since our establishment in 2002. Feel free to get in touch with us today to learn more about our specialty and commodity products.

What Is an Additive Masterbatch?

This type of masterbatch is slowly yet surely becoming a common item used in the manufacturing process. Additive masterbatches are available in numerous varieties, with each type containing select properties that can help improve your end plastic product. Nowadays, they are used in various industries, including plastics, chemicals, paints, and food.

Why Do Manufacturers Use Additive Masterbatches?

Many companies utilize the materials provided by additive masterbatches suppliers in the Philippines because of the various properties these non-food ingredients can impart to plastics. Some of these include:

UV Stabilizer

Used in many plastics exposed to UV radiation, this type of additive masterbatch prevents the degradation of polyurethane and other polymers in plastics. They enable items to last for up to five years without the product needing any treatment or re-dyeing, giving it a longer lifespan than its other counterparts on the market.

These additives are commonly made from organic molecules, such as benzophenones, benzotriazoles, and oxanilides. Furthermore, they improve the UV stability of plastics by absorbing UVA and UVB rays. However, when they absorb ultraviolet light, they release heat and lower the temperature at which polymer chains break down, making them last longer.


This type of additive masterbatch is often added to promote corrosion resistance. Aside from protecting your plastics’ gloss and mechanical properties, they can ensure that polymers don’t degrade immediately at high temperatures.

Antioxidant masterbatches also have the ability to slow down oxidation, which causes the rubber to harden and become brittle. This makes it an ideal additive for products that need protection from contact with air or water over time, such as automotive parts, electrical wires, and plumbing pipes.

Lubricants and Demolding Agents

As a part of the plastics manufacturing process, most plastic parts are molded to create the desired shape. These parts are then typically cooled down before being moved to a different part of the facility, where they will be designed to have a more finished look.

Demolding agents are chemicals added to the polymer to make the surface slick and more malleable when coming out of the mold. As a result, this prevents any damage that could occur, like cracking or chipping. Similarly, lubricants are used when molding plastics are utilized with different types of additives. They help with flow control and consistency in specific applications.

Foaming Agents

Additive masterbatches that function as foaming agents are essential in the plastics industry. When mixed with a resin, they expand to large volumes by creating gas bubbles as well as a plastic foamed product. They help with weight reduction, shrinkage prevention, form stability, flow characteristics improvement, and more.

Additionally, they are typically used in injection molding and extrusion processes. Their primary function in this procedure is to reduce the viscosity of molten polymers, thus allowing for easier processing through machinery.

Antistatic Agents

This type of additive masterbatch is widely used in the production of plastics, rubber, paper, paint binders, and asphalt. As antistatic agents, they act as a protective coating against static electricity accumulation in the polymer mixture they’re added to before extrusion.

Plastics and textiles have low conductivity, which is why they are highly prone to static electricity. This buildup occurs to unbalanced charges and can cause plastic sheets to stick together, become dry, or accumulate large amounts of dust.

In addition, they are available in dry form, which is why they are first combined with water before being used. Some manufacturers, however, opt to use them as a surface coating by applying them to a product’s exterior.

Nucleating Agents

After they’re incorporated with plastics, nucleating agents form nuclei to promote the growth of crystals in the polymer melt. They boost the crystallization of semi-crystalline polymers by presenting a heterogeneous surface to the mixture, making the process itself more thermodynamically favorable.

As a result, the temperature at which the polymer begins to crystallize is increased in addition to the rate of nucleation and crystallization. Nucleating agents also promote the development of smaller and more numerous spherulites. Some of their most common applications include the creation of medical syringes and vials, houseware, and automotive parts.

Anti-Blocking Agents

Blocking is the term used when two adjacent layers of film adhere to each other. Since it causes defects and damages to products, many companies have invested in chemical substances that prevent it from happening.

Commonly added to plastic films and bags, anti-blocking additive masterbatches prevent the sheets from sticking together. They help lessen the adhesion of the surfaces of products made from similar materials.

More traditional and inorganic additives, including silica and talc, reduce polymer to polymer contact by increasing the micro-roughening of the surface. This allows for much easier handling since now you won’t have to worry too much about your products tearing at the slightest force used to open them or separate them from one another.
