Polybutylene succinate (PBS) is a biodegradable and biobased polymer that is used in various applications, including packaging, textiles, and agricultural films. Like other biodegradable polymers, PBS can be susceptible to hydrolysis, especially in the presence of moisture. To enhance its resistance to hydrolysis, an anti-hydrolysis agent can be added.

Here are some considerations when adding an anti-hydrolysis agent to PBS:

  1. Choice of Anti-Hydrolysis Agent:

    • Select an anti-hydrolysis agent that is suitable for use with PBS. Common types include hindered phenols, phosphites, and other stabilizers. The specific choice may depend on the processing conditions and the intended application of the PBS product.

  2. Incorporation during Processing:

    • Anti-hydrolysis agents are typically added during the processing of polymers. In the case of PBS, the agent can be mixed with the PBS resin before extrusion, injection molding, or other processing methods.

  3. Masterbatch Formulations:

    • Anti-hydrolysis agents can be formulated into masterbatches, which are concentrated mixtures of additives. These masterbatches can be easily added to the PBS during processing, simplifying the incorporation of the agent.

  4. Dosage Levels:

    • Determine the effective dosage of the anti-hydrolysis agent for the specific PBS formulation and application. The optimal level may vary, and it's crucial to avoid overuse or underuse of the anti-hydrolysis agent.

  5. Processing Conditions:

    • Consider the processing conditions during the production of PBS products. Factors such as temperature, residence time, and processing parameters can influence the effectiveness of the anti-hydrolysis agent.

  6. Testing and Quality Control:

    • Conduct thorough testing to assess the hydrolytic stability of PBS with the anti-hydrolysis agent. Implement quality control measures to ensure consistency in the manufacturing process.

  7. Environmental Conditions:

    • Consider the environmental conditions to which the PBS products will be exposed. Understanding the humidity levels and potential water exposure in the application environment can help guide the selection and application of the anti-hydrolysis agent.

  8. End-Use Considerations:

    • Evaluate the specific requirements of the end-use application. If the PBS product will be used in outdoor applications or in contact with water, a robust anti-hydrolysis strategy may be necessary.

Always follow the specific guidelines and recommendations provided by the manufacturer of the anti-hydrolysis agent for the most accurate and effective use in PBS applications. Testing the performance of PBS with the chosen anti-hydrolysis agent under relevant environmental conditions is crucial to ensure effective protection against hydrolysis.
