Thermoplastic Polyurethane (TPU) is a highly adaptable polymer, but its inherent flammability can limit its use in safety-critical applications. NINGBO INNO PHARMCHEM CO.,LTD. specializes in providing effective solutions to overcome these limitations, with a focus on halogen-free flame retardants like Aluminum Hypophosphite. Understanding how these additives work is key to appreciating their value and ensuring optimal application.

Aluminum Hypophosphite operates primarily through a condensed phase mechanism. When exposed to heat or flame, it undergoes decomposition, releasing phosphorus-containing compounds. These compounds act to promote char formation on the surface of the TPU. This char layer serves as a physical barrier, insulating the underlying polymer from heat and oxygen, and also preventing the release of flammable volatile gases. This process effectively interrupts the combustion cycle. The high phosphorus content in our Aluminum Hypophosphite contributes significantly to its char-forming ability, making it a highly efficient flame retardant for TPU.

The effectiveness of our Aluminum Hypophosphite as a flame retardant for plastics is further enhanced by its synergistic effects when used in combination with other additives, such as nitrogen-containing compounds. NINGBO INNO PHARMCHEM CO.,LTD. can provide guidance on formulating TPU compounds that achieve superior flame retardancy, such as the UL94-V0 rating, with minimal impact on the material's other desirable properties. This approach to compounding flame retardant TPU is crucial for developing high-performance materials that meet stringent industry standards.

Beyond its flame retardant efficacy, Aluminum Hypophosphite offers other critical advantages. Its halogen-free nature means it does not contribute to the formation of harmful dioxins and furans during combustion, a significant environmental and health benefit. Furthermore, it demonstrates excellent thermal stability and resistance to migration, ensuring the long-term performance of the TPU product. This makes it an ideal choice for applications requiring durability and safety, such as in automotive interiors or electronic enclosures.
