聚偏二氟乙烯 (PVDF)
3M Advanced Materials Division
3M™ Dyneon™ PVDF 31508/0003 is a flexible copolymer of VF2 and CTFE, exhibiting very low shrinkage and excellent impact resistance. PVDF 31508/0003 also has a very low brittleness temperature, for excellent low temperature performance. This material is ideal for insulation and buffering materials for wire and cable applications and for tubing. PVDF 31508/0003 has excellent flame and smoke performance, with an LOI of 65. PVDF 31508/0003 is designed for high speed extrusion, and can be processed using a variety of conventional thermoplastic conversion techniques. As with all PVDF grades, PVDF 31508/0003 also possesses very good chemical and temperature resistance.
