O nosso parceiro GTS especializou-se na fabrica\u00e7\u00e3o de pe\u00e7as polim\u00e9ricas de alto desempenho.\n

\nOs pol\u00edmeros de alto desempenho s\u00e3o pol\u00edmeros que apresentam propriedades mec\u00e2nicas, t\u00e9rmicas, qu\u00edmicas e el\u00e9tricas excecionais em compara\u00e7\u00e3o com os pl\u00e1sticos padr\u00e3o. Estes materiais s\u00e3o concebidos para funcionar em condi\u00e7\u00f5es extremas e oferecer um desempenho superior em diversas aplica\u00e7\u00f5es.\n

<\/div><\/div><\/div><\/div><\/div><\/div>
Eis algumas caracter\u00edsticas comuns dos termopl\u00e1sticos de alta performance:\n
    \n
  • Elevada resist\u00eancia t\u00e9rmica<\/b> eles podem resistir a altas temperaturas sem perder as suas propriedades mec\u00e2nicas.<\/li>\n
  • Resist\u00eancia qu\u00edmica<\/b> eles s\u00e3o resistentes a muitos produtos qu\u00edmicos agressivos.<\/li>\n
  • Resist\u00eancia mec\u00e2nica<\/b> : oferecem uma elevada resist\u00eancia mec\u00e2nica, incluindo boa resist\u00eancia ao desgaste e \u00e0 fadiga.<\/li>\n
  • Isolamento el\u00e9trico<\/b> certos pol\u00edmeros de alta performance s\u00e3o excelentes isolantes el\u00e9tricos.<\/li>\n
  • Estabilidade dimensional<\/b> eles mant\u00eam as suas formas e dimens\u00f5es mesmo em condi\u00e7\u00f5es dif\u00edceis.<\/li>\n
  • Leveza<\/b> frequentemente, estes pl\u00e1sticos s\u00e3o leves, mantendo uma elevada resist\u00eancia.<\/li>\n<\/ul>\n

    O PTFE e os seus comp\u00f3sitos<\/h2>\n
    \n

    O Politetrafluoretileno (PTFE): um pol\u00edmero excecional<\/h3>\nO PTFE, mais conhecido como Teflon\u00ae, \u00e9 um fluoropol\u00edmero conhecido pelas suas propriedades \u00fanicas. A sua estrutura molecular consiste em \u00e1tomos de carbono ligados a \u00e1tomos de fl\u00faor, criando uma liga\u00e7\u00e3o carbono-fl\u00faor excecionalmente forte. Esta liga\u00e7\u00e3o confere ao PTFE v\u00e1rias carater\u00edsticas not\u00e1veis:\n
      \n
    • Resist\u00eancia ao calor: <\/b>o PTFE pode resistir a altas temperaturas sem perder as suas propriedades mec\u00e2nicas, tornando-o ideal para aplica\u00e7\u00f5es a alta temperatura (at\u00e9 327\u00b0).<\/li>\n
    • Antiaderevente - excelente coeficiente de atrito: <\/b>A superf\u00edcie do PTFE \u00e9 extremamente lisa, o que o torna antiaderente. \u00c9 por isso que \u00e9 comummente utilizado em revestimentos antiaderentes para utens\u00edlios de cozinha, moldes industriais e outras aplica\u00e7\u00f5es industriais onde a redu\u00e7\u00e3o do atrito e da ader\u00eancia \u00e9 essencial.<\/li>\n
    • Resist\u00eancia qu\u00edmica: <\/b>o PTFE \u00e9 altamente resistente a uma vasta gama de produtos qu\u00edmicos: \u00e1cidos (oleum, \u00e1gua r\u00e9gia, \u00e1cido n\u00edtrico fumegante), bases (soda c\u00e1ustica ou potassa concentradas), \u00e1lcoois, cetonas e hidrocarbonetos. Resiste ao \u00e1cido fluoroantim\u00f3nico, o \u00e1cido mais forte conhecido atualmente, que dissolve o vidro. <\/li>\n
    • Isolamento el\u00e9trico: <\/b>Devido \u00e0 sua baixa condutividade el\u00e9trica, o PTFE \u00e9 amplamente utilizado em cabos e conectores el\u00e9tricos.<\/li>\n<\/ul>\n

      PTFE carregado<\/h3>\nA associa\u00e7\u00e3o do PTFE com outros materiais para formar comp\u00f3sitos permite combinar as propriedades espec\u00edficas de cada um, criando assim produtos com desempenho melhorado.\nOs comp\u00f3sitos \u00e0 base de PTFE s\u00e3o geralmente refor\u00e7ados pelas seguintes cargas:\n
      \n\n\n\n\n\n
      A fibra de vidro<\/td> \nResist\u00eancia melhorada \u00e0 compress\u00e3o e ao desgaste.<\/td>\n<\/tr>\n
      O carbono<\/td> \nExcelente resist\u00eancia \u00e0 compress\u00e3o e ao desgaste. Boa condutibilidade t\u00e9rmica. Baixa permeabilidade.<\/td>\n<\/tr>\n
      O grafite<\/td> \nBoa condutibilidade t\u00e9rmica. Baixo coeficiente de atrito e permeabilidade.<\/td>\n<\/tr>\n
      O bronze<\/td> \nDiminui\u00e7\u00e3o do flu\u00eancia a temperatura ambiente. Excelente resist\u00eancia ao desgaste. Boa condutibilidade t\u00e9rmica.<\/td>\n<\/tr>\n<\/table>\nAplica\u00e7\u00f5es<\/b>
      \nPara al\u00e9m dos revestimentos antiaderentes e dos cabos el\u00e9tricos, o PTFE \u00e9 usado na fabrica\u00e7\u00e3o de juntas de veda\u00e7\u00e3o, componentes para a ind\u00fastria alimentar, a ind\u00fastria qu\u00edmica, a aeron\u00e1utica, a eletr\u00f3nica e at\u00e9 mesmo em alguns dispositivos m\u00e9dicos (implantes m\u00e9dicos, por exemplo) devido \u00e0 sua biocompatibilidade.\n
