Introduction to single-sided aluminum foil 100 thick rock wool board for insulation materials in the petroleum industry? Single sided aluminum foil rock wool board refers to the insulation material of rock wool board covered with a layer of aluminum foil, which is further divided into single-sided, double-sided or multi sided aluminum foil products. In the field of petrochemicals, insulation of equipment such as pipelines, storage tanks, and reaction vessels is a key link to ensure production safety and reduce energy consumption costs. Single sided aluminum foil 100 thick rock wool board has become an ideal choice for pipeline insulation in the petroleum industry due to its excellent insulation performance, A-level fire resistance, and moisture-proof and thermal insulation functions.

Rock wool itself is an inorganic fiber material with characteristics such as non flammability, high temperature resistance, and good chemical stability; The surface aluminum foil layer provides moisture-proof, vapor proof, heat reflection, and mechanical protection functions, and the combination of the two forms a composite insulation effect of "1+1>2".
The aluminum foil layer of rock wool board plays three key roles:
1. Moisture and vapor barrier
Aluminum foil has extremely low water vapor permeability, forming a dense vapor barrier with a hydrophobicity rate of ≥ 98%.
2. Thermal radiation reflection
In the operation of high-temperature pipelines, thermal radiation heat transfer accounts for a large proportion.
3. Mechanical protection
The aluminum foil layer has a certain degree of tear resistance and wear resistance

The core performance advantages of rock wool board are as follows:

Project	Index / Indicator
Bulk Density (kg/m³)	600±10%	900±10%
Compressive Strength for Thickness ＜ 20 mm (15% Compression in Thickness Direction) (MPa)	≥0.8	≥3.0
Compressive Strength for Thickness ≥ 20 mm (15% Compression in Thickness Direction) (MPa)	≥0.8	≥3.0
Permanent Linear Change on Heating, % (1000℃ × 12h)	0～-2	0～-2
Thermal Conductivity, W/(m·K) (Hot Surface Temperature: 350℃)	≤0.1	≤0.12
Flexural Strength (MPa)	≥2.0	≥3.0
