Organic nucleating agents are compounds used in polymers to promote and control the crystallization process, enhancing the material’s properties. Typical properties of organic nucleating agents include
High Melting Point
To remain stable and active during the high temperatures of polymer processing.
Effective Nucleation
They create nucleation sites that facilitate the formation of crystalline regions in the polymer matrix.
Improved Polymer Properties
Clarity
Mechanical Strength
Solubility and Compatibility
To ensure proper dispersion within the polymer matrix.
Chemical Stability
To withstand the processing conditions without decomposing.
Low Concentration Required
Effective nucleating agents can often achieve desired effects at low concentrations. ( Typically around 0.1-0.5% by weight)
Environmental and Safety Considerations Should be safe for use in food grade plastics and should be US FDA approved compound.
