BP1: 10x Bolts, 10x Nuts, 10x Washers. Material: PVDF. Type: Socket Head Bolts. Length: 20 mm. Diameter: 4 mm. Pitch: 0.7 mm. SKU: 522.. BP2: Outstanding chemical and thermal resistance, as well as extraordinary piezoelectric and electro-mechanical properties.. BP3: PVDF is mechanically stronger than PTFE or PFA polymer. PVDF absorbs little or no water after 24 hours of exposure.. BP4: It exhibits excellent mechanical strength, tensile strength, and abrasion resistance, balancing durability with flexibility. PVDF also has good wear and abrasion resistance.. BP5: Repeated removal and refitting is possible, with excellent resistance to stripping in high-torque applications.. || PRODUCT DESCRIPTION SUMMARY: PVDF has the rare ferroelectric property of retaining its polarisation when the electric field is removed. PVDF is widely used in applications where high chemical resistance, thermal stability and piezoelectric properties are required. It has excellent resistance to acids, bases, solvents, ultraviolet (UV) and gamma radiation. PVDF offers remarkable fire resistance, high chemical resistance and exceptional mechanical strength. It performs well in tension, bending, torsion and compression, while maintaining elasticity, surface hardness and dimensional stability. Notably, PVDF absorbs little to no water after 24 hours of exposure and will not swell or change in a wet environment.. || Please see the technical image illustration for size references.
