🚨 **Official SINOYQX Emergency Statement
The Hong Kong Fire Exposes the Urgent Need for Higher Flame-Resistance Standards in Building Materials**
On November 28, 2025, a tragic fire broke out at Hong Kong’s Tai Po Hung Fuk Estate, causing significant casualties.
Preliminary findings from the Hong Kong SAR Government indicate that combustible EPS/XPS foam boards installed around window openings and façade areas accelerated vertical fire spread, becoming a major contributing factor.
As a company specializing in melamine foam flame-resistant materials,
SINOYQX expresses deep condolences to the families affected.
This tragedy reminds the global construction industry that:
**The flame-resistance classification of materials can determine the difference between containment and catastrophe.
B2/B3 combustible materials pose high, unacceptable risks.**
01｜Fire Risks of Building Materials Have Been Severely Underestimated
EPS/XPS foams are commonly used for:
- External wall insulation
- Temporary enclosure and façade protection
- Construction-phase blocking
- Window opening and shaft sealing
However, they fall under B2/B3 combustible classifications, exhibiting:
- Very low ignition temperatures
- Rapid upward flame spread along façades
- Melting and flaming droplets causing secondary ignition
- Dense smoke and toxic gas release
- “Chimney effect” propagation through openings and shafts
The Hong Kong incident demonstrates again:
Low-cost combustible materials often result in high-cost human and structural losses.
02｜Global Trend: From Low-Standard Flame Retardants to High-Level Flame-Resistance and System-Based Fire Protection
International building codes are converging toward a clear framework:
✔ A-Class non-combustible materials → primary structure
✔ B1-class intrinsic flame-resistant materials → functional layers & composite assemblies
✔ System-level fire engineering → replacing stand-alone “flame-retardant materials”
Applicable to:
- High-rise façade systems
- Hospitals, airports, transit systems
- Fire-rated cavity sealing in construction
- Energy stations, data centers, underground spaces
- Locations prone to melting-drip propagation
The industry is shifting from:
“Combustible materials + simple flame-retardant coatings”
to:
“Non-combustible systems + intrinsic flame-resistant materials + engineered fire protection assemblies”
In this transformation, melamine foam (B1 class) has become a globally recognized high-performance flame-resistant solution.
**03｜SINOYQX Melamine Foam:
B1-Class Intrinsic Flame Resistance for High-Level Building Fire Safety**
SINOYQX melamine foam is classified as B1 flame-resistant under GB 8624 and EN 13501-1.
Its flame resistance comes from its molecular structure, not from additive flame retardants.
✔ Intrinsic flame resistance: non-melting, non-dripping, non-propagating
In a fire, the foam carbonizes and forms an insulating char layer:
- No “firefall” dripping like EPS/XPS
- No molten flow
- Slower flame-spread rate
✔ Extremely wide operating temperature range (approx. -200°C to +240°C)
Suitable for:
- Flame-resistant cavity filling
- Construction-phase opening sealing
- Metro stations, airports, hospitals
- LNG, cold-chain, energy storage applications
✔ Ultra-lightweight (as low as 4 kg/m³), easily engineered, low VOC
- Available in large-format panels
- Compatible with A-class non-combustible materials
- Provides acoustic absorption + thermal insulation + flame resistance
✔ Lower smoke and toxicity, improving life safety and evacuation time
While no material can “prevent all fires,”
B1-class intrinsic flame-resistant melamine foam significantly delays fire development and minimizes melt-drip hazards, buying life-saving evacuation time.
04｜Key Application Recommendations for SINOYQX Melamine Foam in Building Safety
① Replace combustible materials in construction-phase temporary sealing
Ideal for:
- Window openings
- External façade protection
- Mechanical/electrical shaft openings
- Temporary enclosure and blocking
Replacing EPS/XPS with melamine foam greatly reduces melt-drip ignition risks.
② B1-class acoustic–thermal functional layer in high-rise buildings
Can be integrated as:
- Auxiliary layer with A-class non-combustible boards
- Composite layer with metal panels or aerogel sheets
- Flame-resistant acoustic systems
Forming:
“A-Class Non-Combustible System + B1-Class Functional Layer”
to ensure both safety and comfort.
③ Fire-resistant acoustic systems for public infrastructure
Applicable for:
- Metro & railway systems
- Hospitals & schools
- Airports & terminals
- Tunnels & underground spaces
Meets engineering requirements under EN, GB, and ASTM standards.
05｜The Hong Kong Fire Will Likely Accelerate Higher Fire-Safety Standards Across Asia
Clear global trends include:
- 🔺 Stronger fire-resistance requirements for temporary construction enclosure
- 🔺 Restrictions on B2/B3 materials near façade openings
- 🔺 Greater focus on dripping behavior, smoke density, flame-spread rate
- 🔺 A-class + B1-class composite systems becoming mainstream
China’s national standards are also tightening accordingly.
The future will shift from:
Material-level flame resistance → system-level fire performance with transparent classifications.
Melamine foam will continue to serve as a critical B1-class flame-resistant layer in high-safety assemblies.
**06｜SINOYQX’s Position:
Advancing Fire Safety Through High-Level Material Responsibility**
As one of China’s leading melamine foam manufacturers, SINOYQX is committed to:
- Advancing B1-class intrinsic flame-resistant technologies
- Industrializing ultra-lightweight, high-performance melamine foam
- Engineering integrated building fire-protection systems
- Achieving full EN / GB / ASTM certification
- Collaborating with design institutes and engineering contractors worldwide
We firmly believe:
**Flame-resistance classification is not just a specification—
it is a matter of life safety.**
SINOYQX will continue working with global partners to promote the transition toward a truly high flame-resistance era in modern construction.
📌 International Media Q&A (Unified Response)
Q1. Is SINOYQX suggesting the Hong Kong fire was caused by materials?
No. We do not assign blame. The statement reflects material science and global fire-behavior data.
Q2. Is melamine foam an A-class non-combustible material?
No. It is a B1-class flame-resistant material and should be paired with A-class systems for optimal performance.
Q3. Can melamine foam prevent similar incidents?
It cannot guarantee prevention but can significantly reduce melt-drip ignition and delay flame spread, improving evacuation conditions.
Q4. Will cost hinder the adoption of melamine foam?
Not in critical areas. Small volume, high impact—excellent cost-performance ratio.
Q5. Is SINOYQX willing to support fire-safety improvements in Hong Kong and mainland China?
