Abstract: | Microencapsulated ammonium polyphosphate (MAPP) is prepared using hydroxyl silicone oil by in situ polymerization and characterized
by XPS. Microencapsulation gives MAPP better water resistance and flame retardance compared with APP in thermoplastic polyurethane
(TPU). Thermal stability and fire resistance behavior have been analyzed and compared. The LOI value of the TPU/MAPP composite
is higher than that of the TPU/APP composite. The UL 94 rating of the TPU/MAPP composite is V-0 at the 20 wt% additive level,
whereas TPU/APP gives V-2 rating at the same loading level. The water resistant properties of the TPU composites are studied.
Results of the cone calorimeter and microscale combustion calorimeter experiment show that MAPP is an effective flame retardant
in TPU compared with APP. |
