Polyhydroxybutyrate PHB oo leh CAS 26744-04-7
PHB waxaa soo saara noolaha yaryar, sida muuqata iyadoo laga jawaabayo xaaladaha walbahaarka jir ahaaneed. Inta badan waa xaalad nafaqooyin xaddidan leh. Polymer-ku wuxuu inta badan ka yimaadaa isku-darka kaarboonka (laga bilaabo gulukooska ama istaarijka) waxaana u isticmaala noolaha yaryar qaab molecule kaydinta tamarta ah dheef-shiid kiimikaadka marka ilo kale oo tamar caadi ah aan la heli karin.

PHB waxay leedahay fursado ballaaran oo lagu isticmaalo agabka caafimaadka, balaastikada burbursan, qalabka miiska la tuuri karo, muraayadaha muraayadaha, baakadaha, daaweynta wasakhda, alaabta carruurtu ku ciyaarto iyo meelo kale.
Beeraha: side baaba'aya oo loogu talagalay filimada beeraha, sunta cayayaanka iyo bacriminta muddada dheer shaqeeya
Daawada: Tolmo qalliin, ciddiyaha xusulka, beddelka lafaha, beddelka xididdada dhiigga Warshadaha: agabka baakadaha, alaabada nadaafadda, xafaayadaha, agabka firfircoon ee indhaha
Dhinaca agabka caafimaadka, polyhydroxybutyrate waxaa loo isticmaali karaa in lagu diyaariyo agabka daawada sii daaya ee sii daaya, agabka injineernimada unugyada, iwm. Dhinaca baakadaha, alaabada burburka polyhydroxybutyrate badanaa waa kaarboon laba ogsaydh iyo biyo, taas oo la jaanqaadaysa fikradda horumarinta cagaaran iyo ilaalinta deegaanka ee hadda jirta.
