Formula: PVDF
Form: Disk
Material: Polyvinylidene fluoride (PVDF)
CAS Number: 24937-79-9
Commodity: Polymers
The PVDF Disk is a fluoropolymer product within Goodfellow's extensive range of plastic disks. With 48 sizes available, they offer excellent chemical resistance as well as good mechanical strength and low friction properties. PVDF disks are used in chemical processing equipment as valve seats and bearings. They are also ideal as electrical insulators and chemical-resistant liners in the chemical and pharmaceutical industries.
