Red phosphorus flame retardants are highly favored for their excellent flame-retardant efficiency, but their characteristics such as high hygroscopicity and tendency for spontaneous combustion have limited their application in light-colored products. Through microencapsulation technologies such as vacuum coating, their compatibility and processing safety can be effectively improved, enabling red phosphorus to be stably used in light-colored engineering plastics, thereby offering greater design flexibility for high-performance halogen-free flame-retardant materials.
Costs keep fluctuating while supply and demand quietly jostle for position—why is the PA6 market in April “prone to rising but resistant to falling”? And how will flame retardant materials be affected?
To achieve efficient flame retardancy in TPU materials, the alignment of the decomposition temperature of phosphorus-based flame retardants with the substrate is crucial, as it directly impacts flame retardancy efficiency and property retention. The differences in the application of various types of phosphorus-based flame retardants in TPU is a subject worth in-depth exploration.
