Antihydrolysis Agent 362 Powder Application in TPU

As you may already know, PU materials are widely used in various industries due to their exceptional properties such as flexibility, resistance to abrasion, and overall strength. However, one of the challenges faced by manufacturers and end-users of PU products is their susceptibility to hydrolysis, which is the breakdown of the material in the presence of water or moisture over time.

In the water-based polyurethane system, the addition amount is 4-7% of the resin content in the solution, and it is recommended that the drying temperature be higher than 50 ℃;

In the water-based acrylic acid system, it reacts with carboxyl groups with an addition amount of 3-6%, and it is recommended to ripen afterwards.

In general, when using an anti-hydrolysis agent powder in Thermoplastic Polyurethane (TPU) applications, the goal is to enhance the material's resistance to hydrolysis, which can occur when TPU is exposed to moisture or humid conditions. Here are some general steps you might consider, but be sure to refer to the product documentation for accurate information:

  1. Material Compatibility:

    • Ensure that the anti-hydrolysis agent is compatible with TPU. This information should be available in the product datasheet or technical documentation provided by the manufacturer.

  2. Dosage:

    • Determine the recommended dosage of the anti-hydrolysis agent. This is often expressed as a percentage of the total TPU formulation. Adding too much or too little may affect the performance of the material.

  3. Mixing:

    • Thoroughly mix the anti-hydrolysis agent with the TPU resin. This can be done during the compounding process, typically during extrusion or other melt-blending processes.

  4. Processing Conditions:

    • Follow the recommended processing conditions, including temperature and residence time, to ensure proper dispersion of the anti-hydrolysis agent within the TPU matrix.

  5. Testing:

    • Conduct appropriate testing to verify the effectiveness of the anti-hydrolysis agent in improving the material's resistance to hydrolysis. This may involve exposure testing under simulated or actual environmental conditions.

  6. Quality Control:

    • Implement quality control measures during manufacturing to ensure consistency in the dispersion of the anti-hydrolysis agent in the TPU products.

  7. Environmental Considerations:

    • Consider the intended application and the environmental conditions the TPU products will be exposed to. This can guide the selection and application of the anti-hydrolysis agent.

Always refer to the specific guidelines provided by the manufacturer of the anti-hydrolysis agent for the most accurate and effective use in TPU applications. If there have been updates or new developments in the product since my last knowledge update, the manufacturer's documentation will have the latest and most relevant information.
