In construction, automotive, electronics, and industrial maintenance, balancing fire safety with material performance remains a core challenge for engineers. Traditional foams often fail to combine high expansion, strong adhesion, and reliable flame retardancy. Now, Shanghai XMC New Material Technology Co., Ltd. introduces a breakthrough solution: our Two‑Component Graphene Fireproof Foaming Adhesive XMC7119, which integrates graphene‑enhanced technology with a polyurethane‑based reactive foaming system.
The addition of graphene is not a simple additive. Studies show that graphene‑based nanomaterials significantly improve the thermal stability of polyurethane foams and delay ignition. Our product leverages this principle: while retaining the outstanding thermal insulation and mechanical properties of polyurethane foam, it greatly enhances flame retardancy and smoke suppression. It achieves a high industry‑standard flame‑retardant grade, is self‑extinguishing when the flame is removed, and produces no toxic gases during combustion – making it ideal for high‑safety environments such as high‑rise buildings, hospitals, subways, and precision equipment rooms.
| Parameter | Value / Characteristic |
|---|---|
| Mixing ratio (A:B) | 1:1 |
| Working time (25°C) | 20–30 s |
| Foaming time (25°C) | 20–30 s |
| Full curing time | 8–10 min (temperature‑dependent) |
| Expansion ratio | 8‑12 times (volume expansion) |
| Cured density | 50–70 kg/m³ |
| Service temperature range | –40°C to +120°C |
| Adhesive strength (on metal) | ≥2.5 MPa |
The fast working window and 8‑12× expansion enable efficient filling of complex cavities. The low cured density of only 50–70 kg/m³ supports lightweight design, while the wide temperature tolerance from –40°C to +120°C ensures reliable performance in extreme conditions.
Construction: Ideal for wall insulation, pipe sealing, cable trench fire stopping, and gap filling. Its closed‑cell structure provides sound insulation, thermal insulation, and waterproof sealing – a perfect choice for building fire protection.
Automotive manufacturing: Suitable for cavity filling, noise/vibration damping, and lightweight structural design. With the rapid growth of new energy vehicles, polyurethane foam usage per vehicle has increased by 50% compared to conventional cars, and market demand is growing at ~15% annually.
Electronics & appliances: Used for component fixing and waterproof sealing, offering reliable protection for precision devices.
Industrial maintenance: Quick repair and mold filling significantly reduce downtime and boost maintenance efficiency.
The 1:1 two‑component system works with a dedicated mixing nozzle and a two‑component dispensing gun. Simply clean the substrate (free of oil and dust), inject the mixed material within 20–30 seconds, and allow 8–10 minutes for full curing. Natural curing at 25°C is standard; higher temperature and humidity will accelerate the reaction. Recommended application conditions: 10°C–35°C ambient temperature and humidity ≤80%.
Shanghai XMC New Material Technology Co., Ltd. offers a 12‑month shelf life (unopened original packaging). Store in a dry, dark place at 5°C–25°C, away from heat sources. Each component (A and B) is available in 200 ml cartridges, facilitating convenient transport and on‑site handling.
Let the power of graphene protect every critical gap.
