Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • When purchasing fiber optic rock wool board, it is usually necessary to focus on product specifications, such as density (80-200kg/m ³), thermal conductivity (0.040-0.045W/(m · K)), and temperature resistance (usually applicable to environments ranging from -40 ℃ to 700 ℃), which directly affect the insulation effect of building exterior walls or industrial equipment.
  • In high-temperature scenarios such as petrochemicals and electricity, it is recommended to choose high-density models (≥ 120kg/m ³) of fiber optic rock wool board. Its metal fiber optic structure can enhance tensile strength and is more suitable for pipeline wrapping or large storage tank fire isolation layers.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. For example, manufacturers who provide stable supply for large-scale infrastructure projects in the long term are usually more in line with strict engineering standards.
  • For special scenarios such as fire separation in ship cabins, it is necessary to confirm the hydrophobicity (≥ 98%) and combustion performance (Class A non combustible) of the fiber optic rock wool board. At the same time, it is recommended to screen suppliers with high bidding rates in the past three years through platform statistical information.
