The expended perlite fire proof door core uses perlite as raw material,mixed with some proportion of inorganic adhesive and chemical addition agent.The perlite is natural,will be expended by machine with the high temperature of 1300℃,then the structure will be like honeycomb.The perlite can prevent the high temperature,no poisonous chemical substanecs contained.That's why it is the natural green and environmental friendly fire proof material.

The perlite fire insulation board has passed the National Standard of GB/T5464-1999,National Fire Resistance Test GB8625-2006/A1,and GB18580-2001,CE85:97.

1.24h service of sales and after-sales.

2.EXW price,no extra delivery fee includes.

 Zhangjiagang Tianyuan Machine Manufacturer Co.,Ltd was established in 1998.We are a technical private enterprise professional at biomass carbonization stove,biomass gasification power plant and perlite fireproof board.Several unversities and research institutes have been cooperated with us for a long time.After many years of researching and developing,we have successfully solve the problems of bio wastes and environment protection.We own many Chinese patents and has formed a complete system of independent intellectual property rights.

1.Are you manufacturer or trading company?

We are manufacturer,we have our own production lines.We can produce perlite board for 2100*900*(25-70)mm.Different sizes have different prices.

2.What is the raw material?

The raw materials are natural perlite and some inorganic high strength adhesive.Our fireproof board is different from MgO board.We make the perlite expended,not just pour them in a mould,different tech from others.

3.Any clients are using your boards?

We have clients from Australia,Vietnam,Thailand, Dubai etc and also China.

4.How about the fireproof time?

At least 60min,even the thickness of 25mm.It is not so goodlooking,but it is a really natural and high-qualited fireproof product.
