What is PPO FR-V0?
PPO FR-V0 is PPO in the FR-V0 grade — choose for enclosures, busbar supports and PV/telecom parts requiring V-0 with retained dielectric performance. PPO FR-V0 has a yield strength of 55 MPa (7.98 ksi) and a tensile strength of 55 MPa (7.98 ksi) — stronger than 62% of polymer grades. Elongation at break is 35% and the elastic modulus is 2.5 GPa (0.363 Msi). PPO FR-V0 has a density of 1.1 g/cm³ (0.0397 lb/in³), lighter than 66% of polymer grades.

Working with PPO FR-V0
Is PPO easy to machine?
Machines easily with sharp carbide tools, high speed and light feeds; keep parts cool and avoid stress risers — the amorphous matrix is notch-sensitive and can craze if solvent coolants are used (air or water only).
Can PPO be welded?
Excellent ultrasonic, hot-plate, spin and vibration welding; solvent bonding with chlorinated solvents works but leaves residual stress, and annealing is advised before service.
Can PPO be formed, bent or molded?
Inject at 260–310 °C melt / 70–110 °C mold with pre-drying 2–4 h at 100 °C; high melt viscosity needs generous gates and runners, and shrinkage is low and isotropic (0.5–0.7%) in unfilled grades.
What surface finishes work on PPO?
Takes paint, hot stamping, laser marking and electroless plating well after etch; avoid aromatic/ketone-based primers and thinners which cause environmental stress cracking.

PPO FR-V0 — frequently asked
What is PPO FR-V0 used for?
PPO FR-V0 is typically used for electrical enclosures, pump housings, plumbing fittings, automotive interior trim and bus bar insulation. In short: very low water absorption; dimensionally stable amorphous blend; weldable and platable.
What is the yield strength of PPO FR-V0?
PPO FR-V0 has a typical yield strength of 55 MPa (7.98 ksi) and a tensile strength of 55 MPa (7.98 ksi) — stronger than 62% of polymer grades. Strength varies by condition: see the 12 listed tempers.
Is PPO FR-V0 easy to machine?
Reasonably — machinability is rated good (68/100, better than 71% of polymer grades). Machines easily with sharp carbide tools, high speed and light feeds; keep parts cool and avoid stress risers — the amorphous matrix is notch-sensitive and can craze if solvent coolants are used (air or water only).
Can PPO FR-V0 be welded?
Yes — weldability is rated good (68/100). Excellent ultrasonic, hot-plate, spin and vibration welding; solvent bonding with chlorinated solvents works but leaves residual stress, and annealing is advised before service.
What surface finishes work on PPO FR-V0?
Takes paint, hot stamping, laser marking and electroless plating well after etch; avoid aromatic/ketone-based primers and thinners which cause environmental stress cracking.

What is the maximum service temperature of PPO FR-V0?
PPO FR-V0 is rated for continuous use to about 95°C (203 °F), and briefly to 130°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between PPO UNF and PPO FOAM?
UNF is the default condition — general-purpose choice: best toughness/electrical balance and easiest molding; use where 100 °C service and moderate stiffness are enough. FOAM: foam-molded thick-wall housings and enclosures where stiffness-per-weight and low tooling pressure matter more than surface finish. Yield strength is 60 MPa in UNF versus 34 MPa in FOAM.
