What is ABS-Like FR HT-V0?
ABS-Like FR HT-V0 is ABS-Like FR in the HT-V0 grade — pick for FR housings that see soldering-adjacent heat, hot-air ageing or automotive under-hood soak tests. ABS-Like FR HT-V0 has a yield strength of 45 MPa (6.53 ksi) and a tensile strength of 58 MPa (8.41 ksi) — weaker than 65% of polyurethane grades. Elongation at break is 4% and the elastic modulus is 2.3 GPa (0.334 Msi). ABS-Like FR HT-V0 has a density of 1.2 g/cm³ (0.0434 lb/in³), heavier than 87% of polyurethane grades. Its glass-transition temperature is 115°C (239 °F). NAT-V0 is the default condition FabDigit quotes; HT-V0 is available on request or by drawing note.

- MF-V0Use for flat, dimensionally stable FR panels and brackets where stiffness and low shrink beat toughness.45 MPa tensile
- V2-IMChoose when snap-fits and drop performance matter more than a full V-0 rating.44 MPa tensile
Working with ABS-Like FR HT-V0
Is ABS-Like FR easy to machine?
Machines and drills easily with sharp carbide and air blow; FR/mineral fillers dull tools and the dust should be extracted — avoid heat build-up above ~80 °C to prevent gumming.
Can ABS-Like FR be welded?
Thermoset: cannot be heat-welded; join with 2-part epoxy or PU adhesive, or design FR-rated inserts/screw bosses.
Can ABS-Like FR be formed, bent or molded?
Degas both components, cast into silicone tools at 40–70 °C under vacuum, demould in 20–60 min and post-cure 2–4 h at 70–80 °C; keep wall thickness ≥2 mm for reliable V-0 and mind the short pot life of FR-loaded resin.
What surface finishes work on ABS-Like FR?
Sands, primers and paints well (including EMI shielding paint); no plating without a conductive base coat, and light UV yellowing means top-coating for exterior use.
ABS-Like FR 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 |
|---|---|---|
| polyether/polyester polyol (A-side)with catalyst, defoamer and pigment | 40 – 55 | 46 |
| MDI / MDI-prepolymer isocyanate (B-side)aromatic isocyanate hardener | 30 – 45 | 38 |
| phosphorus flame retardant (RDP/TCP-typehalogen-free systems; some grades use brominated FR + Sb2O3 | 4 – 14 | 9 |
| aluminium trihydrate / mineral fillersmoke suppressant / char former | 0 – 12 | 5 |

What is ABS-Like FR HT-V0 used for?
ABS-Like FR HT-V0 is typically used for battery enclosures, aircraft interiors and electronics. In short: flame-retardant rigid PU (UL94 V-0 capable).
What is the yield strength of ABS-Like FR HT-V0?
ABS-Like FR HT-V0 has a typical yield strength of 45 MPa (6.53 ksi) and a tensile strength of 58 MPa (8.41 ksi) — weaker than 65% of polyurethane grades. Strength varies by condition: see the 5 listed tempers.
Is ABS-Like FR HT-V0 easy to machine?
Yes — machinability is rated very good (75/100, better than 80% of polyurethane grades). Machines and drills easily with sharp carbide and air blow; FR/mineral fillers dull tools and the dust should be extracted — avoid heat build-up above ~80 °C to prevent gumming.
Can ABS-Like FR HT-V0 be welded?
Not readily — weldability is rated not recommended (10/100). Thermoset: cannot be heat-welded; join with 2-part epoxy or PU adhesive, or design FR-rated inserts/screw bosses.
What surface finishes work on ABS-Like FR HT-V0?
Sands, primers and paints well (including EMI shielding paint); no plating without a conductive base coat, and light UV yellowing means top-coating for exterior use.
Can ABS-Like FR HT-V0 be formed, bent or molded?

What is the maximum service temperature of ABS-Like FR HT-V0?
ABS-Like FR HT-V0 is rated for continuous use to about 100°C (212 °F), and briefly to 140°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
