Polyphthalamide (aka. PPA, High Performance Polyamide) chikamu chiduku che thermoplastic synthetic resin mumhuri ye polyamide (nylon) inotsanangurwa apo 55% kana kupfuura ma moles e carboxylic acid chikamu chechikamu chinodzokorora mu polymer cheni inoumbwa nemusanganiswa. ye terephthalic (TPA) uye isophthalic (IPA) asidhi. Kutsiviwa kwealiphatic kunosarudza nekunhuhwirira kunosarudza mumusana wepolymer kunowedzera nzvimbo yekunyungudika, tembiricha yegirazi, kuramba kwemakemikari uye kuoma.
PPA based resins inoumbwa kuita zvidimbu kutsiva simbi mumashandisirwo anoda kupisa kwakanyanya kupisa senge mota dzemagetsi echitima zvikamu, imba yekupisa tembiricha yemagetsi ekubatanidza uye zvimwe zvakawanda zvinoshandiswa.
Iyo tembiricha yekuchinja yegirazi yePPA inowedzera sezvo huwandu hweTPA hunowedzera. Kana inopfuura 55% yeasidhi chikamu chePPA yakagadzirwa kubva kuIPA, ipapo iyo copolymer ndeye amorphous. Zvimiro zve semi crystalline polymers v amorphous polymers zvinotsanangurwa kumwe kunhu zvakadzama. Nenguva pfupi, crystalline inobatsira nemakemikari kuramba uye mechanical zvivakwa pamusoro pegirazi shanduko tembiricha (asi pazasi pekunyungudika). Amorphous polymers akanaka muhondo uye pachena.
PPA zvinhu zvine zvakanakisa musanganiswa zvivakwa, izvo zvinoita zvakanaka pakupisa, magetsi, emuviri uye makemikari zvivakwa. Kunyanya pasi pekushisa kwepamusoro PPA ichine kuomarara uye kusimba kwakanyanya, pamwe neakanakisa dimensional kurongeka uye kugadzikana.
Yakakosha kushandisa giredhi yeMotokari yemvura temp yekudzora musangano uye thermostat muviri chikamu.
