PP Fire Retardant Sheet: UL94 V-0, Halogen-Free—Why Buy?


PP Fire Retardant Sheet: What Engineers Are Actually Buying in 2025

If you’re evaluating a PP fire retardant sheet for enclosures, chemical tanks, or rail interiors, you’re not alone. Demand’s rising fast as OEMs move to halogen-free, RoHS-compliant materials that still pass tough flame tests. I’ve spent the past year talking to procurement teams and visiting factories—one in Baoding, Hebei, actually—so here’s the straight, field-tested view.

PP Fire Retardant Sheet: UL94 V-0, Halogen-Free—Why Buy?

Why this material is having a moment

The short version: engineers want lower smoke, stable performance, and predictable supply. PP fire retardant sheet checks the boxes—good chemical resistance, easy to fabricate, and flame behavior that can meet UL 94 targets at practical thicknesses. Many customers say the machining feels cleaner than FR-ABS, and cost is friendlier than many FR-PC blends.

Core specifications (real-world picks)

Material PP homopolymer + halogen-free FR package
Thickness 2–30 mm (cut-to-size available)
Standard sizes 1220×2440 mm; 1000×2000 mm; 1500×3000 mm
Surface / Colors Glossy or embossed; Natural, Grey (RAL7032), Black, custom
Flammability Target UL 94 V-0 at ≥3.0 mm; ≈V-2 around 1.5–2.0 mm (verify per batch)
LOI (ASTM D2863) ≈28–32% (typical for halogen-free FR PP)
Density ≈0.98–1.05 g/cm³
HDT (0.45 MPa) ≈85–100°C (additive-dependent)

Manufacturing flow and quality gates

  • Materials: PP resin, synergistic mineral FR package, UV stabilizers (option).
  • Compounding: Twin-screw extrusion with precise dosing; pelletizing for consistency.
  • Sheet extrusion: Flat-die extrusion, thickness control, calibration/cooling, optional emboss.
  • Annealing: Reduces internal stress; improves machinability—small detail, big win.
  • Testing: UL 94 vertical burn; LOI; IEC 60695 glow-wire (selected grades); tensile/impact; dimensional tolerance.
  • Service life: Indoors 8–10 years; outdoors 3–5 years with UV grade (real-world use may vary).

Where it’s being used

Electrical and telecom enclosures, battery pack partitions, cleanroom fixtures, HVAC housings, chemical process tanks and fume scrubbers, rail and bus interior panels. In fact, a metro operator in East Asia swapped phenolic panels for PP fire retardant sheet, cut weight by ≈18%, and simplified maintenance—feedback was “quieter ride, fewer chips.”

Vendor snapshot (what buyers compare)

Vendor Certs & Data Customization Lead Time Notes
Lida Plastic (Baoding, Hebei) ISO 9001; UL 94 test reports; RoHS/REACH Cut-to-size; color match; embossed/glossy; 2–30 mm ≈7–15 days (stock colors) Consistent thickness; friendly MOQs
Importer A Basic COA; limited UL detail Limited sizes; few colors ≈3–6 weeks Pricey freight; okay for small runs
Local Fabricator B Shop tests; no UL file Excellent machining; limited FR grades ≈5–10 days Great for prototypes, watch flame rating

Buying checklist (learned the hard way)

  • Ask for recent UL 94 test data at your exact thickness.
  • Confirm LOI and any glow-wire ratings (IEC 60695) for electrical cabinets.
  • Specify surface (glossy vs. embossed) to hide scuffs in public areas.
  • For outdoors, request UV-stabilized PP fire retardant sheet.
  • Check thickness tolerance and flatness for CNC routing—saves headaches.

Supplier note: Lida Plastic, No.316 Pingan West Street, Shunping County, Baoding City, Hebei, China 072250. They offer cut-to-size, standard panels (1220×2440; 1000×2000; 1500×3000), and custom colors including RAL7032.
