What is PVF ORIENTED?
PVF ORIENTED is PVF in the ORIENTED grade — choose when high tensile modulus and dimensional stability during lamination matter more than conformability. PVF ORIENTED has a yield strength of 60 MPa (8.7 ksi) and a tensile strength of 120 MPa (17.4 ksi) — stronger than 69% of polymer grades. Elongation at break is 60% and the elastic modulus is 2.6 GPa (0.377 Msi). PVF ORIENTED has a density of 1.45 g/cm³ (0.0524 lb/in³), heavier than 86% of polymer grades. Its glass-transition temperature is 40°C (104 °F).
Advantages

Limitations
- Hard to polish — 20/100, worse than 95% of polymer grades
- High embodied carbon — 9 kg CO₂/kg, worse than 88% of polymer grades
- Difficult to machine — 30/100, worse than 87% of polymer grades
- Heavy — 1.45 g/cm³ (0.0524 lb/in³), worse than 86% of polymer grades
- Poor heat conductor — 0.16 W/m·K (0.0924 BTU/hr·ft·°F), worse than 78% of polymer grades

Working with PVF ORIENTED
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 ORIENTED — frequently asked
What is PVF ORIENTED used for?
PVF ORIENTED 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 ORIENTED?
PVF ORIENTED has a typical yield strength of 60 MPa (8.7 ksi) and a tensile strength of 120 MPa (17.4 ksi) — stronger than 69% of polymer grades. Strength varies by condition: see the 3 listed tempers.
Is PVF ORIENTED easy to machine?
Not especially — machinability is rated poor (30/100, worse than 87% of polymer grades). Supplied as thin film — slit, die-cut, laser- or rotary-cut rather than machined; no bulk stock shapes available.
Can PVF ORIENTED be welded?
Not readily — weldability is rated poor (25/100). 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 ORIENTED?
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 ORIENTED 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 ORIENTED?
PVF ORIENTED is rated for continuous use to about 95°C (203 °F), and briefly to 175°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
