What is PVF WHITE-TIO2?
PVF WHITE-TIO2 is PVF in the WHITE-TIO2 grade — pick for photovoltaic backsheets (TPT/KPK constructions) and painted-metal overlays where opacity, reflectance and 25-year weathering are required. PVF WHITE-TIO2 has a yield strength of 40 MPa (5.8 ksi) and a tensile strength of 70 MPa (10.2 ksi) — weaker than 63% of polymer grades. Elongation at break is 120% and the elastic modulus is 2.4 GPa (0.348 Msi). PVF WHITE-TIO2 has a density of 1.68 g/cm³ (0.0607 lb/in³), heavier than 94% of polymer grades. Its glass-transition temperature is 40°C (104 °F).

Working with PVF WHITE-TIO2
Is PVF easy to machine?
Supplied as thin film — slit, die-cut, laser- or rotary-cut rather than machined; no bulk stock shapes available.
Can PVF be welded?
Melt point sits near the decomposition range, so heat sealing is marginal; join by adhesive lamination to primed film or by hot-melt/EVA lamination.
Can PVF be formed, bent or molded?
Not melt-processable in practice — film is produced by solvent/dispersion casting and extrusion of latent-solvent dopes; end users vacuum-form or emboss it below ~150 °C.
What surface finishes work on PVF?
Unprimed surface has very low energy (good release, poor bonding); use factory adhesive primer or corona/flame treatment before painting, printing or lamination.
PVF chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| TiO2 pigmentonly in white/opaque film grades | 0 – 20 | 0 |
| carbon blackonly in black film grades | 0 – 3 | 0 |
| vinyl fluoride (CH2=CHF) repeat unithomopolymer, ~-CH2-CHF- backbone; fluorine content ~41 wt % | balance | — |
PVF WHITE-TIO2 — frequently asked
What is PVF WHITE-TIO2 used for?
PVF WHITE-TIO2 is typically used for solar panel backsheet film, architectural fabric/membrane laminates, aircraft interior decorative film and weatherable graphic overlaminates. In short: best-weathering fluoropolymer film; thin film only, no stock shapes; low-permeability protective laminate.
What is the yield strength of PVF WHITE-TIO2?
PVF WHITE-TIO2 has a typical yield strength of 40 MPa (5.8 ksi) and a tensile strength of 70 MPa (10.2 ksi) — weaker than 63% of polymer grades. Strength varies by condition: see the 3 listed tempers.
Is PVF WHITE-TIO2 easy to machine?
Not especially — machinability is rated poor (28/100, worse than 90% of polymer grades). Supplied as thin film — slit, die-cut, laser- or rotary-cut rather than machined; no bulk stock shapes available.
Can PVF WHITE-TIO2 be welded?
Not readily — weldability is rated poor (30/100). Melt point sits near the decomposition range, so heat sealing is marginal; join by adhesive lamination to primed film or by hot-melt/EVA lamination.
What surface finishes work on PVF WHITE-TIO2?
Unprimed surface has very low energy (good release, poor bonding); use factory adhesive primer or corona/flame treatment before painting, printing or lamination.
Can PVF WHITE-TIO2 be formed, bent or molded?
Not melt-processable in practice — film is produced by solvent/dispersion casting and extrusion of latent-solvent dopes; end users vacuum-form or emboss it below ~150 °C.
What is the maximum service temperature of PVF WHITE-TIO2?
PVF WHITE-TIO2 is rated for continuous use to about 107°C (225 °F), and briefly to 175°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
