PVDF Flat Washer, 3/16", 0.188" ID, 0.5" OD, 0.04" Thick (Pack of 25)

Standard flat washers are an economical choice when your application calls for spacers, shims, or re-enforcements with nominal dimensions only. Polyvinylidene Fluoride, or PVDF, has a useful temperature range of -148 to 300 degrees Fahrenheit. PVDF exhibits similar properties to Kynar, a trade name of the Arkema Corporation. PVDF is generally used in applications requiring high purity, strength, and resistance to solvents, acids, bases and heat. It also generates little smoke during a fire event. PVDF exhibits below average strength as compared to Nylon 6/6, with tensile strength ranging from 5000 to 7000 psi (pounds per square inch) and impact strength of 1.2 foot pounds (on the Izod Impact Scale) as compared to 9000 psi, and 3 foot pounds, respectively. PVDF is stronger than PTFE and could be desirable where PTFE is not strong enough for the application. PVDF will absorb little or no water after 24 hours of exposure (less than 0.05% of weight impact). PVDF also has below average dielectric strength of 260 volts per millimeter (compared to 500 volts/mm for Nylon).

• Flat Washers are an economical choice
• PVDF is suitable for applications that require high purity and low water absorption, along with greater strength than PTFE
• Size Name corresponds to matching screw or bolt size
