Material: Polyvinylidene fluoride (PVDF)
CAS Number: 24937-79-9
Commodity: Polymers
We offer a comprehensive range of PVDF Rods with 29 variations to choose from. Polyvinylidene fluoride (PVDF) is a highly non-reactive and pure thermoplastic fluoropolymer. With outstanding chemical resistance, PVDF rods are valued for their strength and durability across a wide temperature range. Example applications include being used as an insulator in the chemical processing and semiconductor industries. The variations in diameter and length we offer allow you to select the optimal PVDF Rods for your specific application.
