PU Sandwich Panel

.

for a short while.the flammability of this kind of foam plastic can achieve the
grade above B1.
Excellent physical and chemical properties of  duowei compounds determine that
its products are featured with strong flame penetration resistance, corrosion
resistance of smoke, toxicity and form and small volume. Comparing with common
PUR rigid foam, it is well equipped with good thermal stability, excellent fire
resistance, strong flame penetration resistance and low smoke
generation.

developed by DUOCAI is as follows: excessive isocyanurate is added, and cyclic
structure and a higher isocyanate index are introduced to the compound to form
more compact cross linking polyisocyanurate(PIR) and to make rigid foam more
stable from the interior. Though this process, the rigid foam id featured with
better heat resistance and fire resistance and can endure the temperature of 250

first succeed in the online continuous foaming technique of multi-component PU.
The production line may complete proporting and blending only one time at the
production center or factory, and make online adjustments from time to time
according to the temperature, so as to produce building panels different from
others featured with high strength, energy saving, and grades of PUR boards
according to requirements of customers.
Polyisocyanurate is referred as PIR for short. Production of PIR composite panel

PUR/PIR clad panel. Production ability of hard material PUR are 800,000m2 and
soft materials PUR is 1,200,000m2 per year.
In the aspect of material proportioning and technique output, DUOCAI PUR
production lines adopts the advanced six-component blending pouring technology
of online automatic microcomputer operation(SIEMENS) in the world, making DUOCAI

light weight,no pollution,height of the corrugation is 40mm,clear width is
