No\u00e7\u00f5es b\u00e1sicas sobre o material TPU PPF
\nTPU (poliuretano termopl\u00e1stico): Capacidade de autorrepara\u00e7\u00e3o obtida atrav\u00e9s da recombina\u00e7\u00e3o din\u00e2mica das cadeias moleculares, capaz de reparar riscos finos \u00e0 temperatura ambiente e de atingir uma maior efici\u00eancia de repara\u00e7\u00e3o a altas temperaturas (por exemplo, acima dos 60 \u2103)
\nPPF (Pel\u00edcula de prote\u00e7\u00e3o da pintura<\/a>): Estrutura de poliuretano multicamadas, elevada resist\u00eancia ao impacto, mas a capacidade de autorregenera\u00e7\u00e3o depende do substrato de TPU
\nPrinc\u00edpios da autocura e da repara\u00e7\u00e3o t\u00e9rmica
\nAuto-repara\u00e7\u00e3o: as cadeias moleculares do segmento macio do TPU sofrem uma desloca\u00e7\u00e3o tempor\u00e1ria ap\u00f3s a ocorr\u00eancia de riscos e s\u00e3o restauradas ao seu estado original atrav\u00e9s de ativa\u00e7\u00e3o t\u00e9rmica (como a luz solar ou \u00e1gua quente), reparando riscos \u2264 40 \u03bcm
\nRepara\u00e7\u00e3o t\u00e9rmica: requer uma temperatura elevada, superior a 60 \u2103, e atividade suficiente das cadeias moleculares para se conseguir uma repara\u00e7\u00e3o profunda; no entanto, a repara\u00e7\u00e3o repetida pode causar \u201cdanos de mem\u00f3ria\u201d
\nCompara\u00e7\u00e3o t\u00e9cnica e sugest\u00f5es de sele\u00e7\u00e3o
\nEfici\u00eancia da repara\u00e7\u00e3o: o TPU permite uma repara\u00e7\u00e3o r\u00e1pida \u00e0 temperatura ambiente (3 segundos), enquanto o PPF requer temperaturas elevadas e apresenta uma baixa efici\u00eancia
\nSitua\u00e7\u00f5es em que se aplica: o TPU \u00e9 adequado para pequenos danos do dia a dia, enquanto o PPF \u00e9 mais adequado para ambientes sujeitos a impactos intensos
\nComo evitar armadilhas: o TPU de m\u00e1 qualidade tem tend\u00eancia a amarelar; os produtos genu\u00ednos exigem a verifica\u00e7\u00e3o de c\u00f3digos anti-contrafa\u00e7\u00e3o e uma constru\u00e7\u00e3o profissional<\/p>\n
