Bio-SAH™ 342Liquid Anti-hydrolysis Agent Used in PBAT with Biodegradable Multifunctional Benefits Ultraviolet (UV) Absorbers

Polybutylene adipate terephthalate (PBAT) is a biodegradable and compostable polymer often used in the production of bioplastics and biodegradable products. PBAT is susceptible to hydrolysis, which is the chemical breakdown of the polymer chains in the presence of water. To enhance the resistance of PBAT to hydrolysis, anti-hydrolysis agents are commonly employed. These agents help to maintain the integrity and performance of PBAT in applications where exposure to moisture is a concern.

Polybutylene adipate terephthalate (PBAT) is a biodegradable and compostable polymer often used in the production of bioplastics and biodegradable products. PBAT is susceptible to hydrolysis, which is the chemical breakdown of the polymer chains in the presence of water. To enhance the resistance of PBAT to hydrolysis, anti-hydrolysis agents are commonly employed. These agents help to maintain the integrity and performance of PBAT in applications where exposure to moisture is a concern.

Here are some types of anti-hydrolysis agents that may be used with PBAT:

  1. Phosphites:

    • Certain phosphite-based stabilizers are effective anti-hydrolysis agents. These compounds act as antioxidants and help prevent the degradation of PBAT due to hydrolysis.

  2. Phosphonites:

    • Phosphonite-based stabilizers are another class of additives that can function as anti-hydrolysis agents. They provide protection against the detrimental effects of water exposure on PBAT.

  3. Polymeric Stabilizers:

    • Some polymeric stabilizers are designed specifically for use with biodegradable polymers like PBAT. These stabilizers offer multifunctional benefits, including anti-hydrolysis properties.

  4. UV Absorbers:

    • Ultraviolet (UV) absorbers are often included in formulations to protect PBAT from UV-induced degradation, and they can indirectly contribute to anti-hydrolysis performance by reducing the impact of environmental factors.

  5. Phenolic Antioxidants:

    • Phenolic antioxidants are commonly used to enhance the thermal and oxidative stability of polymers. In certain cases, they may also provide anti-hydrolysis protection to PBAT.

The specific choice of anti-hydrolysis agent depends on factors such as the processing conditions, the intended application of PBAT, and the environmental conditions it will encounter. It's essential to consider the overall formulation of PBAT, including the combination of stabilizers and other additives, to achieve the desired performance and longevity.

For detailed and application-specific guidance, it is recommended to consult with polymer formulation experts or material suppliers who specialize in biodegradable polymers. They can provide tailored recommendations based on your specific requirements and processing conditions.
