FAQs:
What makes aluminum hypophosphite a halogen-free flame retardant?
Aluminum hypophosphite is an inorganic phosphorus-based compound that contains no bromine or chlorine, making it an environmentally friendly, halogen-free flame retardant option.
How does aluminum hypophosphite work to retard flames in epoxy adhesives?
It works through multiple mechanisms: an endothermic reaction absorbs heat, it forms an insulating char layer on the material surface, and it dilutes flammable volatiles, collectively slowing combustion.
What polymers is this flame retardant suitable for?
It is suitable for flame retardant modification of various polymers including epoxy adhesive, PBT, PET, PA, TPU, ABS, and EVA, often used with stabilizers or synergistic flame retardants.
What is the typical addition amount for effective flame retardancy?
Due to its high phosphorus content and efficiency, it requires only a small addition amount to achieve effective flame retardant performance in the final product.
