The fireproof core board produced by our company uses expended perlite as raw material,mixed with certain proportion of inorganic high strength adhesive.There is no MgO mixed.With the high temperature above 1300℃,the perlite will be expended.At the same time ,the inside structure will like honycomb.The perlite fireproof board is totally a natural enveironmental-friendly product.No other chemical materials and poisonous things contained.

1.The boards will be packed with wooden pallet and film.

2.Delivery time:depend on the quantity,usually a 20'container needs 1 month.

 1.Are you manufacturer or trading company?

We are manufacturer,we have our own production line.

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 thin board with 25mm.It is not so goodlooking,but it is a really natural and high-qualited fireproof product.
