Flame Retardant Ceppa

CEPPA

Chemical name: CEPPA 3-(Hydroxyphenylphosphinyl) propanoic acid.
CAS NO : 14657-64-8
ELINCS NO : 99-04-1212
EC NO : 411-200-6
Structure:
APPLICATION FIELDú¦ PET,nylon,fiber galss etc
Characteristics and Applications:
It is an organic and fire-resistant compound . CEPPA is a low smoke and non-halogen flame retardant.CEPPA belong to reaction-category fire-resistant additive according to the way of addition
It can be used to polyester fiber (PET), nylon , fiberglass etc . but at present the technology of using in polyester is most mature and stable . Take how to use in PET polyester a example to explain how to use CEPPA : CEPPA AND PTD , EG(glycol) are used together to copolymerize and produce flame retardant polyester slices(PET). The advised addition of CEPPA is about 4-5.5%,which can make LOI(limited oxygen index) meet as high as 32%.And flame retardant polyester slices will be spinned to produce all kind of polyester fiber.
CEPPA is always added in process of ES REACTION or PA REACTION.
