美国3M增韧抗冲PVDF Dyneon 31008/0003
3M Dyneon PVDF 31008/0003 is a flexible copolymer of VF2 and CTFE, exhibiting very low shrinkage and excellent impact resistance. Dyneon PVDF 31008/0003 also has a very low brittleness temperature, for excellent low temperature performance. This material is ideal for insulation and buffering materials for many wire and cable applications and for tubing. PVDF 31008/0003 has excellent flame and smoke performance, with an LOI of 60. PVDF 31008/0003 is designed for high speed extrusion, and can be processed using a variety of conventional thermoplastic conversion techniques. As with all PVDF grades, PVDF 31008/0003 also possesses very good chemical and temperature resistance.

化学结构中以氟一碳化合键结合，这种具有短键性质的结构与氢离子形成***稳定***牢固的结合．因而氟碳涂料具有特异的物理化学性能，不但有很强的***性和抗冲击性能，而且在***严酷与恶劣的环境中有很高的抗褪色性与抗紫外线性能。
PVDF是一种高强度、***的物质，通常是用来制造水管的。PVDF膜可以结合蛋白质，而且可以分离小片段的蛋白质，***初是将它用于蛋白质的序列测定，因为硝酸纤维素膜在Edman试剂中会降解，所以就寻找了PVDF作为替代品，虽然PVDF膜结合蛋白的效率没有硝酸纤维素膜高，但由于它的稳定、***使它成为蛋白测序理想的用品，一直沿用至今。PVDF膜与硝酸纤维素膜一样，可以进行各种染色和化学发光检测，也有很广的适用范围。
