摘要:
A method of manufacturing a PTFE stretched film that has higher tensile strength at its breaking point. In the method, a resin composition is obtained by mixing an emulsion of PTFE (A) with a number average molecular weight of 5×106 or more and an emulsion of PTFE (B) with a number average molecular weight of 1×106 to 4×106 so that the solid content ratio (A/B) of the PTFE (A) and the PTFE (B) is 99/1 to 10/90. The mixed emulsion is subjected to compression molding in a melted state under a reduced-pressure atmosphere to obtain a film.
摘要(中):
制造在其断裂点具有较高拉伸强度的PTFE拉伸膜的方法。 在该方法中,通过将数均分子量为5×10 6以上的PTFE(A)的乳液与数均分子量为1×106〜4的PTFE(B)的乳液混合,得到树脂组合物 ×106,使得PTFE(A)和PTFE(B)的固体成分比(A / B)为99/1〜10/90。 将混合乳液在减压气氛下在熔融状态下进行压缩成型,得到膜。
