Principais caracter\u00edsticas: boa estabilidade qu\u00edmica, resist\u00eancia ao calor, resist\u00eancia ao frio, resist\u00eancia a \u00f3leo, \u00e1gua, g\u00e1s, produtos qu\u00edmicos e outros meios, alta resist\u00eancia mec\u00e2nica, resist\u00eancia a alta press\u00e3o e boa resist\u00eancia \u00e0 abras\u00e3o. Coeficiente de atrito muito baixo, boa autolubrifica\u00e7\u00e3o.<\/p>

Em termos gerais, o PTFE preenchido \u00e9 mais adequado para ser usado como material de veda\u00e7\u00e3o hidr\u00e1ulica do que o PTFE puro. Os enchimentos comumente usados s\u00e3o p\u00f3 de bronze, fibra de vidro, fibra de carbono, etc.; esses enchimentos podem reduzir o coeficiente de expans\u00e3o t\u00e9rmica, melhorar a condutividade t\u00e9rmica, aumentar a resist\u00eancia ao desgaste e melhorar o desempenho mec\u00e2nico. O PTFE em si n\u00e3o \u00e9 el\u00e1stico, por isso \u00e9 frequentemente usado em conjunto com elast\u00f4meros de borracha.<\/p>

Temperatura de trabalho: -30\u2103\uff5e+ 200\u2103 (de acordo com a temperatura de trabalho para selecionar o anel de veda\u00e7\u00e3o de material apropriado)
Principais usos: para a fabrica\u00e7\u00e3o de an\u00e9is de veda\u00e7\u00e3o, an\u00e9is resistentes ao desgaste e an\u00e9is-guia (correias) para os materiais de veda\u00e7\u00e3o mais comumente usados em m\u00e1quinas, amplamente utilizados em m\u00e1quinas de engenharia, m\u00e1quinas leves e quase todos os setores.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
