What is mPP FR-V0?
mPP FR-V0 is mPP in the FR-V0 grade — required for electrical enclosures and appliance parts; FR package cuts impact strength and clarity. mPP FR-V0 has a yield strength of 25 MPa (3.63 ksi) and a tensile strength of 26 MPa (3.77 ksi) — weaker than 74% of polymer grades. Elongation at break is 30% and the elastic modulus is 1.7 GPa (0.247 Msi). mPP FR-V0 has a density of 1.02 g/cm³ (0.0368 lb/in³), lighter than 72% of polymer grades. Its glass-transition temperature is -5°C (23 °F). UNF is the default condition FabDigit quotes; FR-V0 is available on request or by drawing note.

Working with mPP FR-V0
Is mPP easy to machine?
Machines easily with sharp positive-rake tools, high speed and low feed; use coolant/air blast to avoid gumming and expect springback on tight tolerances.
Can mPP be welded?
Excellent hot-plate, hot-gas, ultrasonic, IR and spin welding with PP filler rod; no solvent bonding — surface must be flame/corona/plasma treated before adhesive or print.
Can mPP be formed, bent or molded?
Narrow MWD gives low melt elasticity: high-clarity injection molding is easy (melt 200–250 °C, mold 20–40 °C), but blow molding, extrusion foaming and deep thermoforming need higher melt strength or a broadened blend.
What surface finishes work on mPP?
Not paintable or platable as-molded; requires corona/flame/plasma activation or adhesion primer, and dyeing is not possible — use masterbatch coloring or in-mold texture/film decoration.
mPP 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.

mPP FR-V0 — frequently asked
What is mPP FR-V0 used for?
mPP FR-V0 is typically used for flexible packaging film, medical device components, non-woven fibers, retort packaging and heat-seal layers. In short: clearest polypropylene class; low-extractable medical PP; best heat-seal PP.
What is the yield strength of mPP FR-V0?
mPP FR-V0 has a typical yield strength of 25 MPa (3.63 ksi) and a tensile strength of 26 MPa (3.77 ksi) — weaker than 74% of polymer grades. Strength varies by condition: see the 11 listed tempers.
Is mPP FR-V0 easy to machine?
Not especially — machinability is rated fair (40/100, worse than 82% of polymer grades). Machines easily with sharp positive-rake tools, high speed and low feed; use coolant/air blast to avoid gumming and expect springback on tight tolerances.
Can mPP FR-V0 be welded?
Yes — weldability is rated very good (70/100). Excellent hot-plate, hot-gas, ultrasonic, IR and spin welding with PP filler rod; no solvent bonding — surface must be flame/corona/plasma treated before adhesive or print.
What surface finishes work on mPP FR-V0?
Not paintable or platable as-molded; requires corona/flame/plasma activation or adhesion primer, and dyeing is not possible — use masterbatch coloring or in-mold texture/film decoration.
Can mPP FR-V0 be formed, bent or molded?
Narrow MWD gives low melt elasticity: high-clarity injection molding is easy (melt 200–250 °C, mold 20–40 °C), but blow molding, extrusion foaming and deep thermoforming need higher melt strength or a broadened blend.
What is the maximum service temperature of mPP FR-V0?
mPP FR-V0 is rated for continuous use to about 95°C (203 °F), and briefly to 120°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between mPP UNF and mPP IM?
UNF is the default condition — baseline clear/natural mPP homopolymer for injection molding, sheet and CPP film where stiffness and clarity matter. IM: choose for sub-zero drop-impact requirements in housings, thin-wall crates and automotive interior parts. Yield strength is 33 MPa in UNF versus 22 MPa in IM.
