What is RPET FR-V0?
RPET FR-V0 is RPET in the FR-V0 grade — for electrical/electronic parts requiring V-0 at 0.8–1.5 mm together with a recycled-content claim. RPET FR-V0 has a yield strength of 52 MPa (7.54 ksi) and a tensile strength of 115 MPa (16.7 ksi) — stronger than 56% of polymer grades. Elongation at break is 2% and the elastic modulus is 9.5 GPa (1.38 Msi). RPET FR-V0 has a density of 1.68 g/cm³ (0.0607 lb/in³), heavier than 94% of polymer grades. Its glass-transition temperature is 78°C (172 °F).

Working with RPET FR-V0
Is RPET easy to machine?
Machines like virgin PET — sharp positive-rake tools, high speed, low feed and air cooling; stress-relieve or anneal thick stock to avoid crazing, and expect chip stringing.
Can RPET be welded?
Ultrasonic, hot-plate, vibration and RF/heat sealing all work well; solvent bonding is poor, so use cyanoacrylate/epoxy or mechanical joints for structural bonds.
Can RPET be formed, bent or molded?
Dry to <50 ppm moisture at 160–170 °C for 4–6 h (IV loss is otherwise irreversible); melt 260–290 °C, cold mould (10–30 °C) for clear amorphous parts or 130–140 °C for crystallized parts; chain extenders help restore melt strength for extrusion and foaming.
What surface finishes work on RPET?
Takes print, corona/flame treatment, metallization and hot stamping; not paintable without primer, and surface haze/gel specks from contaminants limit optical-grade finishes.
RPET 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.

RPET FR-V0 — frequently asked
What is RPET FR-V0 used for?
RPET FR-V0 is typically used for recycled fiber/textiles, food & beverage bottles, sheet/film and strapping. In short: recycled-content PET; lower, variable IV; bottle-to-bottle food grade.
What is the yield strength of RPET FR-V0?
RPET FR-V0 has a typical yield strength of 52 MPa (7.54 ksi) and a tensile strength of 115 MPa (16.7 ksi) — stronger than 56% of polymer grades. Strength varies by condition: see the 6 listed tempers.
Is RPET FR-V0 easy to machine?
Not especially — machinability is rated fair (35/100, worse than 84% of polymer grades). Machines like virgin PET — sharp positive-rake tools, high speed, low feed and air cooling; stress-relieve or anneal thick stock to avoid crazing, and expect chip stringing.
Can RPET FR-V0 be welded?
Not readily — weldability is rated poor (30/100). Ultrasonic, hot-plate, vibration and RF/heat sealing all work well; solvent bonding is poor, so use cyanoacrylate/epoxy or mechanical joints for structural bonds.
What surface finishes work on RPET FR-V0?
Takes print, corona/flame treatment, metallization and hot stamping; not paintable without primer, and surface haze/gel specks from contaminants limit optical-grade finishes.
Can RPET FR-V0 be formed, bent or molded?
Dry to <50 ppm moisture at 160–170 °C for 4–6 h (IV loss is otherwise irreversible); melt 260–290 °C, cold mould (10–30 °C) for clear amorphous parts or 130–140 °C for crystallized parts; chain extenders help restore melt strength for extrusion and foaming.
What is the maximum service temperature of RPET FR-V0?
RPET FR-V0 is rated for continuous use to about 140°C (284 °F), and briefly to 110°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
