A placa de poliuretano, mais comumente chamada de PIR ou simplesmente placa de PU, \u00e9 um material de isolamento r\u00edgido altamente eficiente. Amplamente utilizado nos setores de constru\u00e7\u00e3o e automotivo, ele \u00e9 formado por uma rea\u00e7\u00e3o qu\u00edmica espec\u00edfica; a cria\u00e7\u00e3o de uma estrutura de c\u00e9lulas fechadas \u00e9 a caracter\u00edstica que o define. Uma combina\u00e7\u00e3o quase perfeita de v\u00e1rias propriedades faz com que esse material seja a escolha preferida de muitos profissionais.<\/p>\n

Principais vantagens da placa de poliuretano<\/h2>\n

Isolamento t\u00e9rmico excepcional<\/h3>\n

Um dos valores mais baixos de condutividade t\u00e9rmica que os materiais de isolamento comuns podem atingir \u00e9 obtido pela placa de poliuretano. A estrutura de c\u00e9lulas fechadas mencionada anteriormente ret\u00e9m gases inertes, proporcionando, de fato, uma resist\u00eancia quase completa a todas as formas de fluxo de calor. S\u00e3o mantidas temperaturas consistentes no interior de edif\u00edcios ou ve\u00edculos, com redu\u00e7\u00f5es diretas associadas aos custos de aquecimento e resfriamento.<\/p>\n

Alta rela\u00e7\u00e3o entre resist\u00eancia e peso<\/h3>\n

Por mais leve que seja a placa, ela apresenta uma rigidez estrutural not\u00e1vel e algum n\u00edvel de resist\u00eancia \u00e0 compress\u00e3o. A facilidade de manuseio e instala\u00e7\u00e3o (f\u00edsica ou n\u00e3o) n\u00e3o compromete a durabilidade; telhados, pain\u00e9is de parede e, at\u00e9 certo ponto, carrocerias de ve\u00edculos, todos se beneficiam dessa caracter\u00edstica.<\/p>\n

Resist\u00eancia \u00e0 umidade e \u00e0 \u00e1gua<\/h3>\n

Novamente, devido \u00e0 natureza de c\u00e9lula fechada, a absor\u00e7\u00e3o de umidade \u00e9 inerentemente limitada. O isolamento fibroso falha em condi\u00e7\u00f5es \u00famidas, cedendo, apodrecendo e perdendo as propriedades de isolamento; a placa de poliuretano n\u00e3o falha. O desempenho a longo prazo e a prote\u00e7\u00e3o quase constante contra mofo s\u00e3o garantidos.<\/p>\n

Durabilidade e longevidade<\/h3>\n

Envelhecimento, v\u00e1rios fatores de intemp\u00e9ries e exposi\u00e7\u00e3o qu\u00edmica quase infinita est\u00e3o todos dentro da resist\u00eancia da placa - a integridade estrutural e o desempenho de isolamento geral podem ser mantidos por muitos anos.<\/p>\n

Aplicativos comuns<\/h2>\n

Constru\u00e7\u00e3o civil<\/h3>\n

Pain\u00e9is isolados para telhado e parede, sistemas de fachada.<\/p>\n

Automotivo<\/h3>\n

Carrocerias de ve\u00edculos comerciais (sendo os cont\u00eaineres frigor\u00edficos um excelente exemplo).<\/p>\n

Armazenamento a frio\/armazenamento<\/h3>\n

C\u00e2maras frias e\/ou todos os espa\u00e7os com temperatura controlada.<\/p>\n

Conclus\u00e3o<\/h2>\n

A placa de poliuretano \u00e9 e sempre ser\u00e1, para mim, um material de isolamento superior. A efici\u00eancia energ\u00e9tica e tudo o que ela permite s\u00e3o parte de seu verdadeiro valor.<\/p>","protected":false},"excerpt":{"rendered":"
