  • Acid Scavengers and Stabilizers - Enhanced Durability

    Polymers are the backbone for products ranging from plastics and rubber to fibers and adhesives.

    To enhance the durability and functionality of polymers, various additives are incorporated during their manufacturing process. Among these additives, acid scavengers and stabilizers play a crucial role in maintaining the integrity and extending the lifespan of polymer products.

    What are Acid Scavengers?

    Acid scavengers are specialized additives that are incorporated into polymers to neutralize acidic impurities. These impurities can stem from different sources, including the polymerization process, environmental exposure, or natural degradation. If left unattended, these acidic compounds can initiate further degradation reactions. This can result in the loss of essential mechanical and thermal properties of the polymer, leading to decreased functionality, discoloration, and unpleasant odors.

    The Role of Stabilizers

    On the other side of the equation are stabilizers. These additives are designed to preserve the properties of polymers by preventing or slowing down their degradation. The main culprits behind polymer degradation are environmental factors such as UV light, heat, and oxygen. By incorporating stabilizers into the polymer matrix, you can significantly extend the lifespan and usefulness of polymer-based products.

    Case Study Lohtragon® B42 and Lohtragon® B68 - Multifaceted Stabilizers and Acid Scavengers

    Lohtragon® B42 | based on Tricalcium Citrate and Lohtragon® B68 | based on Calcium Formate emerge as multifaceted additives in the polymer domain, functioning seamlessly as an acid scavenger and stabilizer. By neutralizing detrimental acids and reinforcing structural stability, they enhance the longevity, resilience, and performance of a myriad of polymer-based products across diverse industries. Their comprehensive compatibility with various polymer types further underscores its versatility and indispensability in contemporary polymer applications.

    Case Study Lohtragon® O01 - From acid scavenger to precipitation agent

    Lohtragon® O01 is used as an acid scavenger in POM as well as a precipitation and coagulation agent in emulsion polymerization due to its pH and solubility profile.


    In summary, acid scavengers and stabilizers are indispensable polymer additives that play a vital role in extending the durability and functionality of polymers. By neutralizing acidic impurities and slowing down degradation, these additives help maintain the polymer's original properties. The Lohtragon® PA range offers a solution in this domain, providing both acid scavenging and stabilization benefits to extend the lifespan of your polymer products.
