冷拉伸、热收缩聚四氟乙烯制品成型技术

Manufacturing Technology of Cold Stretched and Hot Shrinkable PTFE Products

在室温状态下 ,用拉伸的办法使聚四氟乙烯制品变形并对变形后的制品进行热定型处理 ,可以制得热收缩四氟制品。热收缩聚四氟乙烯制品保留了聚四氟乙烯材料的原有特性并可以紧密地贴紧在另一工件上。冷拉伸、热收缩聚四氟乙烯制品成型技术为聚四氟乙烯材料的进一步推广应用拓展了空间。

At room temperature,PTFE items are stretched and then hot calibrated to form hot shrinkable PTFE products.The manufacturing technology of cold stretched and hot shrinkable PTFE products will find wide applications for PTFE material.
