O le a le PDLLA Poly(DL-lactide) CAS 51056-13-9?

PDLLA o se polymer amorphous ma le vevela suiga tioata o le 50-60 ℃ ma le viscosity laina ole 0.2-7.0dl/g. O mea ua faʻamaonia e le FDA ma e mafai ona faʻaaogaina e avea o se fesoasoani mo taʻaloga faʻamaʻi anti-adhesive mucosa, microcapsules, microspheres ma implants mo le faʻasaʻolotoina, ma e mafai foʻi ona faʻaaogaina e pei o faʻamaʻi porous mo le faʻainisinia o le aganuʻu ma le ponaivi poʻo le toe faʻaleleia o mea, e pei o sutures taotoga, faʻapipiʻi, paʻu toto faʻapitoa, faʻapipiʻi toto.

Fa'aaogāga

1. Fomaʻi faʻafomaʻi‌: PDLLA e faʻaaogaina lautele e fai ma faʻatumu mata i le matata o faʻafomaʻi faʻafomaʻi ona o lona lelei sili ona lelei ma le faʻaleagaina. E mafai ona faaosofia ai le gaosiga o le paʻu collagen, faʻaleleia atili ai le paʻu o le paʻu, maanuminumi ma faʻalavelave.

2. Fomaʻi masini‌: PDLLA e faʻaaogaina lautele i le matata o masini faʻafomaʻi, e pei o vailaʻau faʻapipiʻi faʻapipiʻi mo faʻamaʻi faʻamaʻi toto, suture taotoga, kilipa hemostatic, ma isi.

3. Inisinia Tissue‌: E iai foʻi mea taua a le PDLLA i le matata o le inisinia, e pei o le faʻapipiʻiina o ponaivi ma mea e toe faʻaleleia ai ponaivi, faʻainisinia faʻainisinia, ma isi mea.

4. Fa'asa'olotoga fa'asaina: E mafai fo'i ona fa'aoga le PDLLA mo le fa'asa'olotoina o fualaau fa'asaina ma le afifiina fa'asa'o tumau. E ala i le tuʻufaʻatasia ma vailaʻau e fai ai vailaʻau e pei o microspheres poʻo microcapsules, e mafai ona ausia le faʻasaʻoloto lemu ma le faʻaauauina o gaioiga, ma faʻaleleia atili ai le aoga ma le saogalemu o vailaʻau.

5. Fa'aleagaina le fa'atinoga o le PDLLA‌: O le PDLLA e fa'agasolo malie, lea e mafai ai ona tu'uina atu a'afiaga fa'afoma'i umi i totonu ole falema'i. O lona fa'aleagaina o le lactic acid, lea e i'u ina fa'a'avea i le carbon dioxide ma le vai, ma e le o'ona ma le afaina i le tino o le tagata.
