Each type of additive masterbatch has some special properties to improve the end plastic product.
Nucleating agents are compositions, compounds, etc.,that induce the formation of polymer crystals (i.e., regulate and control crystallinity). It’s better defined in chemistry as Nucleating agent is a substance that forms nuclei for the Growth of crystals in a super cooled polymer melt.
read more Nucleating agents are used with polymers that can crystallize in order to speed cycle times. After melting, it is solidification rate of the plastic into a useful shape that controls processing and cycle time.

Nucleation occurs when a small nucleus begins to form in the liquid, the nuclei then grows as atoms from the liquid are attached to it.
The crucial point is to understand it as a balance between the free energy available from the driving force & the energy consumed in forming new interface. There are two types of nucleation namely the homogeneous or spontaneous nucleation and heterogeneous nucleation.
This phenomenon happens when nuclei are formed perfectly in a clean solution where there are no any foreign particles. When semi Crystalline polymers tend to Crystallize from the melt, the particles organize from a Primary nucleus to form complex macro-structures called“ Spherulites”. Properties of the polymer depends upon end size of the spherulite structures

Nucleation involves initial adsorption of macro molecules on its surface. This process is efficient if the foreign body is able to provide a energy matrix for the formation of thermo dynamically favourable crystalline forms. An efficient nucleating agent must have a high energy surface – the large the specific surface, the more efficient it is ..
Nucleating agents facilitates to improve mechanical properties such as stiffness, Heat distortion Temperatures & Crystallization rates. Especially for Injection molding the required high crystallization rates is attributed by the addition of Nucleating agents. The nucleating efficiency depends on factors such as Temperature, Pressure, Stress, Part Thickness, etc and presence of other processing additives .

Key Characteristics of nucleating agent

Nucleating agents promote the crystallization of semi-crystalline polymers. These additives function by presenting a heterogeneous surface to the polymer melt, making the crystallization process more thermo dynamically favorable, facilitating enhanced properties such as flexural modulus and HDT.
They are most widely used in polypropylene (homo- and random co-polymers), where they provide three main benefits: property enhancement, improved molding productivity, and increased transparency. Besides these ,uniform product shrinkage is also observed in the molded components.
They are also useful in other semi-crystalline polymers, including polyesters (PET, PBT) and polyamides.
Adding nucleating agents to the semi-crystalline polymers provides a surface to start the crystal growth. As a result, fast crystal formation will accelerate in many small crystal forms. Cycle times in injection molding are thus reduced.
Also it improves the mechanical properties and stiffness of thermo formed polypropylene parts without affecting polymer density or transparency. It allows the down gauging of polypropylene parts and end products while maintaining the same rigidity.
It is suitable for both virgin and post-consumer resins. Because it doesn’t alter the density of the polymer it doesn’t prevent flotation separation at recycling facilities, so customers can meet sustainability goals.
It gives a unique performance enhancer for PP,PE films. At very low concentration, it provides a good balance between processing stability, mechanical strength and aesthetic properties.
It’s food grade compliant , fit for PCR ( post consumer recycling) and no impact on organo leptic properties on food packaging films ( ie) the aspects of food, water or other substances that create an individual experience via the senses—including taste, sight, smell, and touch.
