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 located in Zhangjiagang City,near Shanghai.we have our own production lines in our factory.

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?

60-120min or longer,even the thickness of 25mm.
