At present, the thermal insulation materials commonly used in building construction include microfiber glass wool products, polyurethane, rubber and plastics. Microfiber glass wool products are a category of glass fibers. It has good heat insulation, sound absorption and sound insulation performance. During the installation and use of microfiber glass wool products, the operation is very simple. It can be cut into any form according to construction requirements. There will be no disconnection or lengthening during use. It is commonly used in various places such as heating, ventilation, and air conditioning, and the effect is very significant. There are many tiny air pores in microfiber glass wool, so the physical properties of glass wool products are relatively stable.

Microfiber glass wool:

1. The appearance is smooth and clean.

2. Combustion performance: Class A non-combustible

3. Low moisture absorption rate

4. Thermal conductivity: 0.032 (w/mk) This product fully meets the technical design requirements in terms of process. And it overcomes the defects of insufficient integrity and poor flexural and impact resistance in the past.

5. Green environmental protection and energy saving products.

Microfiber glass wool has a large number of tiny air pores, which make it play a role in heat preservation, sound absorption, noise reduction and safety protection. It is the best material for building heat preservation, heat insulation, sound absorption and noise reduction. It can absorb a lot of sound energy in the room, reduce reverberation time, and reduce indoor noise.

Polyurethane:

(1) The internal heat generation is large, the high temperature resistance performance is general, especially the humidity and heat resistance is not good. The normal operating temperature range is -40~120℃. If long-term effects are required under high-frequency oscillation conditions or high-temperature conditions, corresponding modification measures must be taken in the structural design or formulation.

(2) Not resistant to strong polar solvents and strong acid and alkali media. At a certain temperature, alcohol, acid, and ketone will swell and degrade the polyurethane elastomer. Solvents such as chloroform, dichloromethane, dimethylformamide, trichloroethylene will swell the polyurethane elastomer at room temperature.

Rubber and plastic:

The nine-vertical closed bubble structure can prevent heat conduction, but the effect is not strong.

The surface heat release coefficient is high.
