Resistance to Fire
The fire resistance performance of rock wool boards is not merely
the simple characteristic of "non-combustibility", but rather it
achieves progressive safety guarantees of "preventing fire
occurrence, controlling fire spread, and reducing fire damage"
through the combined effects of "non-combustion and fire
resistance, high-temperature resistance and structural stability,
low toxicity and reduced hazards". Whether it is the basic
protection for building exteriors or the protection for high-risk
scenarios in industries and transportation, its fire resistance
performance is the core support for meeting safety standards and
reducing fire risks.
Preventing Flame Spread Along Carriers
When open flames occur near pipes or cables, rock wool boards
themselves are non-combustible and do not produce molten drips.
They can block direct flame scorching of pipe/cable surfaces,
avoiding secondary fires caused by melting of cable insulation
layers or damage to gas pipe seals. For example, a cable tray
covered with 50mm-thick rock wool boards can resist flame attack
for 1.5-2 hours in standard fire tests, far exceeding the
flame-retardant duration of ordinary organic protective materials.
Insulating High-Temperature Thermal Radiation
High-temperature thermal radiation during fires can easily cause
premature damage to pipes/cables not directly exposed to flames.
The low thermal conductivity of rock wool boards can effectively
block the transmission of thermal radiation, maintaining the
surface temperature of the clad pipes/cables within a safe range
and ensuring their functional integrity.
Reducing Condensate Hazard
Low-temperature pipes (such as air conditioning refrigerant pipes
and chilled water pipes) are prone to condensation due to
temperature differences. Accumulated water can accelerate pipe
corrosion and cable insulation aging. The insulation performance of
rock wool boards can reduce the temperature difference between the
pipe and the environment, minimizing condensation formation.
Meanwhile, their porous structure can absorb a small amount of
condensate and volatilize it slowly, preventing water accumulation
on the surfaces of pipes.
