Fireproof board

1.Excellent high temperature resistance

Long term use temperature can be stable at 600-1000℃, and can withstand higher temperatures in the short term (some models can instantly withstand temperatures above 1200℃).It can adapt to high temperature conditions such as mold heating, metal die-casting, forging, etc., and will not melt, decompose or structurally fail due to high temperature.

2.Stable physical properties at high temperatures, low thermal shrinkage rate, and no significant size deformation due to temperature changes, ensuring mold clearance and accuracy.

3.Efficient insulation and heat preservation

Having extremely low thermal conductivity (usually between 0.1-0.3 W/(m ·K)), it can effectively block high-temperature transfer on the mold surface, reduce heat loss to other components of the equipment or the environment, and lower energy consumption.

4.It can reduce the temperature difference inside and outside the mold, avoid workpiece forming defects (such as shrinkage, cracks, etc.)caused by uneven temperature, and protect operators and surrounding equipment from high temperature damage.

5.Excellent electrical insulation

High volume resistivity (usually>10 ¹⁴Ω· cm), dielectric strength can reach 20-50 kV/mm, and stable insulation performance can be maintained in harsh environments such as high temperature and humidity.It is suitable for electrical isolation of mold heating systems (such as electric heating molds) to prevent leakage or short circuits.

6.Good mechanical strength

It has certain impact resistance and compressive strength, can withstand the pressure and mechanical vibration when the mold is closed, and is not easily broken or layered.
Cutting, drilling and other processing can be carried out according to the size of the mold, with convenient installation and adaptability to different shapes of mold surfaces.

7.Chemical Resistance

It has corrosion resistance to most acids, bases, oil stains, and metal melts (such as non-ferrous metals such as aluminum and zinc), and will not deteriorate due to chemical reactions caused by contact with these substances, extending its service life.

8.Aging resistance and flame retardancy
Strong anti-aging performance, slow performance degradation after long-term use; And it is non flammable (oxygen index > 40), does not burn when exposed to open flames, and does not release toxic gases, which complies with safety regulations.
