Kedu ihe bụ Chimassorb 944 Cas 71878-19-8?

Chimassorb 944 (CAS 71878-19-8) bụ ihe na-eme ka amine light stabilizer dị elu (HALS) dị n'ime ahụ.

UV Absorber 944 bụ ihe na-eme ka amine dị arọ nke nwere polymerized, nke nwere obere mgbanwe, iguzogide mbugharị, na iguzogide okpomọkụ dị elu. Otu amine ndị na-egbochi na nhazi kemịkalụ nke UV 944 nwere ike ijide radicals efu nke ọma, si otú a na-arụ ọrụ na nkwụsi ike ìhè.

Ọkwa dị elu nke polymeric na-egbochi amine light stabilizer, obere volatilization, obere mbugharị, nkwụsi ike okpomọkụ na mmetụta mgbochi oxidation, njikọta na antioxidants na ihe ndị na-amịkọrọ UV. Enwere ike itinye UV Absorber 944 na polyolefins, olefin copolymers, kamakwa maka polyphenylene ether complexes, polyoxymethylene, amides, ngwakọta PVC na PVC dị nro na siri ike.
