Introduction of Perlite Fire board:

Perlite is known as rock, which is a kind of lava after cooling. People name it perlite due to its fissuring structure of genuine pearl.

Perlite fire board is mainly made of perlite grains which has been expanded rapidly through hige temperature. Meanwhile glassfibre and some inorganic adhesives are added to strengthen its density and fire protection. The board is produced through computer machines with latest industrial technology and advanced production equipment. High temperature, pressure and necessary maintenance are great help to its high quality.

The product owns patent of strength in China mainland and Taiwan area, and effect of fire proof is high after moulding. The main features of the board are good fire-proofing, sound and heat insulation. Its fine fireproofing performance has passed testing of Institution of Tianjin Fire-fighting and Beijing Construction Research Institute. Temperature of back side board is no more than 120`C under testing 45mm thick door core, inside wall and etc.

1)Even coloring:
Our product is one-punch made at certain mould, tolerance of thickness is less than 0.5mm, which makes it fitting perfect between panel and board after gluing, seamless and good heat conduction. There will be no shading with very good fastness, which avoid traditional uneven coloring after painting on surface of fire door.
2)Logo embossing:
Through our one-punch forming, fine product will be finished according to customer’s mould, which reduce a lot of handwork comparing past and fill a gap both domestic and abroad at present.
3)Less production procedure and workload:
We can manufacture most satisfied product according to customer requirements, even special size 900 * 2100 * (30-70) mm, 1150 * 2250 * (30-70) mm. And our product is cut under control by computer, making it a whole board to put into doorframe, no extra cutting or assembling is needed, which reduce a lot of procedure and work not necessary, saving your money and time.
4)Rustless:
As stated above, our product is pressing-made under high temperature and pressure, and moisture content is strictly controlled not more than 7%, while domestic requirement is less than 10%. However, the issue of rustiness in steel door or galvanized steel sheet was unable to solve due to high moisture content while traditional processing.
5)Light specific gravity:
The product is only 250-350kg/m3, which helps not only to lower transportation costs, but also lighten the intensity of labor and reduce the pressure when assembling.
