  • Nucleating Agents for Enhanced Material Properties

    Nucleating agents are designed to control and enhance the crystallization behavior of semi-crystalline polymers.

    Semi-crystalline polymers such as polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET) possess both amorphous and crystalline regions.

    Particularity Around Semi-Crystalline Polymers

    The crystalline regions lend mechanical strength and thermal resistance, while the amorphous regions offer flexibility. The degree and rate of crystallization can significantly influence the properties of the finished polymer product, affecting parameters like mechanical strength, optical clarity, barrier properties, and processability.

    Why Choose Lohtragon® Nucleating Agents for Your Polymer Additives

    Metal salts generally function by lowering the energy barrier required for the initiation of crystallization, thus increasing the rate of nucleation. This results in smaller, more uniform crystals that impart beneficial properties to the polymer. Their high thermal stability makes them particularly useful in applications requiring high processing temperatures. 
    One of the challenges in using metal salts as nucleating agents is achieving uniform dispersion within the polymer matrix. Due to their inorganic nature, they may not be inherently compatible with organic polymers. To overcome this, they are often surface-treated or used in conjunction with organic compatibilizers to improve dispersion and effectiveness.
