Product Overview
Honeycomb Thermal Barrier Fabric (WO-MP-230OR) is a dual-layer protective textile engineered as the critical thermal barrier layer in structural firefighter suits. The meta-aramid face provides flame resistance and comfort against the moisture barrier, while the para-aramid back delivers tear strength and durability against the outer shell. The 3D honeycomb knit structure creates an insulating air gap — the key to reducing heat transfer to the wearer — with <5% heat shrinkage ensuring the barrier stays dimensionally stable under extreme thermal load.
Structure: Honeycomb Knit | Layers: Meta-Aramid Face + Para-Aramid Back | Weight: 230 gsm | Width: 150 cm | Cert: ISO 11612 / NFPA 2112
Key Features
| Heat Shrinkage | <5% — exceptional dimensional stability prevents liner deformation during fire exposure, critical for suit integrity |
| Dual-Layer Construction | Meta-Aramid face (comfort, flame resistance) + Para-Aramid back (strength, durability) — P40s/2 stitch-bonded |
| Honeycomb Structure | 3D knit geometry creates trapped air pockets — maximizes thermal insulation without adding weight |
| Flame Resistance | 100% inherent — no topical chemical treatment. Both fiber layers are non-flammable at the molecular level |
| Tear Strength | Para-aramid back layer provides high tear resistance — withstands the mechanical stress of structural firefighting |
| Certifications | ISO 11612 (Heat & Flame) / NFPA 2112 (Flash Fire) / GB 8965.1 (China Firefighter Standard) |
| Weight | 230 gsm (±5%) — optimal balance of thermal protection and wearer mobility |
| Width | 150 cm (±5cm) — standard garment cutting width |
Applications
| Structural Firefighting | Thermal barrier layer in NFPA 1971-compliant turnout gear — between moisture barrier and outer shell |

FAQ
Q: Why does heat shrinkage matter for thermal barrier fabric?
A: When a thermal barrier shrinks under heat, it pulls away from seams and creates gaps — exposing the wearer to direct heat. WO-MP-230OR's <5% shrinkage rate ensures the barrier maintains full coverage and suit integrity throughout fire exposure. Most conventional thermal liners shrink 8–15% in testing.
Q: How does the honeycomb structure improve thermal protection?
A: The 3D honeycomb knit creates thousands of trapped air cells between the meta-aramid face and para-aramid back. Air is the most effective thermal insulator — this structure dramatically reduces conductive heat transfer without adding weight or bulk to the garment.
Q: Can this fabric be used as a standalone layer or only as a thermal barrier?
A: It is engineered specifically as the middle thermal barrier layer in a 3-layer firefighter suit system (outer shell + moisture barrier + thermal barrier). We also offer compatible meta-aramid face fabrics and para-aramid outer shell fabrics for a complete garment solution.
Q: Do you provide the full ISO 11612 / NFPA 2112 test report?
A: Yes. We provide complete certified test reports including flame spread, heat transfer, thermal shrinkage, and tear strength results. Third-party SGS/Intertek testing available for your specific certification needs.
Why Honeycomb Knit Outperforms Plain Thermal Barriers
- 3× the Air Gap — honeycomb geometry traps 3× more insulating air volume than flat-knit thermal barriers at the same weight, directly improving TPP (Thermal Protective Performance) scores
- <5% Shrinkage Guaranteed — the dual-layer stitch-bonded structure locks both face and back fibers in place, preventing the differential shrinkage that causes plain barriers to curl and gap at seams
- Better Moisture Management — the open honeycomb channels allow moisture vapor to escape rather than condensing inside the suit, reducing steam burn risk during fire suppression
- No Separate Spacer Required — the honeycomb is the spacer — eliminates one assembly step and one failure point in garment construction
