Though plastic products such as heat-resistant plastic film are everywhere in our daily life, we do not be familiar with their composition. All plastics may contain one or more polymers besides additives. Particularly, polymers are not sold until some additive has been added to them such as additive masterbatch.          

Polymer features utilized in plastic products like polymer plastic film may be considerably changed by manufacturing conditions and the addition of additives. With additives, several formulas of basic materials are available, and they provide various services.

Actually, a masterbatch is a combination of one or more additives added to a primary polymer substance for example functional additive masterbatch. There are many advantages to utilizing this mixture, one of which is that it typically results in cost savings since a compounding phase can be eliminated.

If you are looking for the best masterbatches suppliers, you can search online. There are a variety of suppliers. A masterbatch is usually used to color a finished product like anti-rust packing raw material. Hence, they may also contain additional ingredients.

Fillers and Reinforcements:

The term usually refers to the addition of more additives. Materials modification, such as adding fillers, is commonly employed with engineering thermoplastics to obtain a desirable mix of qualities. Using fillers means that plastic material can be elevated from one category to another, such as the commodity resin polypropylene, which can be transformed into an engineering plastic by the use of boosting ingredients.

Impact Modification:

An impact modifier is a type of elastomer or rubber that adds toughness. These additives are commonly used in engineering thermoplastics for applications which demand high impact strength. Moreover, the impact strength of commodity resins can be increased by the inclusion of impact modifiers.

Flame Retardants:

Most polymers will burn because they are carbon-based like polymer masterbatch. You should know that a carbon-based material starts reacting after coming in contact with ambient oxygen, producing carbon monoxide and carbon dioxide. Halogen atoms, such as bromine and chlorine, can produce compounds which are naturally fire or flame retardant. PVC is one of the most notable examples.

Anti-Aging Additives:

As heat and light constantly affect the properties of polymeric materials, anti-aging chemicals are usually utilized with them. The chemical reactions of oxidation, ozone attack, and ultraviolet (UV) assault occur within a material or on its surface and are induced by heat and light.


Polymers should be lubricated on a regular basis so as to prevent the polymer from adhering to the processing equipment or to allow the polymer compound to flow more freely. To be frank, polymer plastic film may display the same feature.

Cross-Linking Additives:

As we know, a wide variety of polymers can be cross-linked, which means they are cured, vulcanized, or set, and after shaping, they can result in either vulcanized rubber or a kind of plastic substance. Sulfur, commonly used with rubbers and peroxides, which are also used with particular polyolefins. Accelerators can definitely accelerate the cross-linking reaction and are frequently associated with cross-linking systems. What’s more, an accelerator can only work effectively in the presence of an activator.
