Polyurethane sandwich panel roof with aluminum foils are the high-end products in today's metal building materials.The reason why it's one kind of the high-end products,it's because the metal panels are integrated with load-bearing,heat-insulating, fire-proof and waterproof function.The panel can be non-toxic and tasteless,and it doesn’t requires no secondary decoration.PIR roof panels with aluminum kraft paper can be regarded as "Almighty player".Why it's so excellent products,it's because of the material it used for panel.

Core material :
PIR is actually called polyurethane modified polyisocyanurate, which is a foam obtained by modifying polyurethane.The performance is quite different from polyurethane.It’s class 1 fireproof level.
PUR is short for polyurethane,which is a polymer having a urethane segment repeating structural unit prepared by reacting an isocyanate with a polyol.Our PUR is class 2 fireproof level.
This sandwich panel realizes a waterproof shunt design, which can reduce the water area of the board and replace the color steel plate with aluminum foil, which improves the high temperature and corrosion resistance of the product.
This sandwich panel can be widely used in food, medicine, electronics, animal husbandry and other industries,etc.
