TPV's (thermoplastic vulcanizates) yakawedzera mukurumbira muzvikamu zvakawanda zveindasitiri. Inofanana kana kudarika yechinyakare (thermoset) rabha mune akawanda maapplication, ichipa akawanda maficha asingawanikwe ezvikamu zvakagadzirwa nerabha yechinyakare. Panguva imwecheteyo, TPV yakakwirira munzira dzakawanda kune thermoplastics, kunyanya PVC.
Kunyangwe kugadzira chisimbiso chakasimba kana chine simba, zvakakosha kuti usatarise kushanda kwenguva refu kweelastomer. Heano mamwe echokwadi aunofanirwa kuziva kana uchisarudza chinhu chechisimbiso chako.
PVC isarudzo yakajairika yezvisimbiso, uye yave iripo kwenguva yakareba. Muchiitiko chedu, zvisinei, PVC inoshanduka haina kumira zvakanaka nekufamba kwemakore, kunyanya kana iri pasi pemhepo inodziya. Muyedzo yekuchembera yekupisa yakaitwa nerabhoritari yakazvimiririra, Reed akabata akawanda eTPV nePVC zvienzaniso mukamuri yekuchembera inopisa kwemavhiki gumi nemaviri pa100째C. Mhedzisiro yacho yaishamisa: zvienzaniso zveTPV zvakachinja zvishoma, asi zvienzaniso zvePVC zvakadzikira neinosvika gumi muzana, uye zvakawoma zvakanyanya uye zvisingaite elastic. Ehe, chisimbiso chako chinogona kusamboona tembiricha idzi, asi mibairo inoratidza kuti zvinhu zviviri izvi zvinozoita sei pakudziya kwakadzika kwenguva yakareba. Zvakare, mamakisi akasiyana eTPV nePVC anogona kuburitsa zvakati siyanei, asi zvakawanikwa izvi zvinoenderana neakawanda ezvinyorwa zviripo. Zvatinowana zvakarongwa pazasi.
