The product is a mixture consisting of polyether polyols, silicone stabilizer, flame retardant and catalys. It is a light yellow liquid at room temperature. It has been developed to produce B1 class fireproof outer wall spraying thermal insulation polyurethane foam in conjunction with polymeric MDI.
close cell polyurethane pu foam for insulation spray
DMJ series polyol is a fully formulated polyol blend developed for spray application of polyurethane rigid foam. The component ratio of has been adjusted to make it suitable for polyurethane foam spraying machine using with a fixed volumetric component ratio of 1-1.2 : 1.
It already contains sufficient quantity of blowing agent HCFC 141b to achieve the foreseen foam density.
High closed-cell rate, good water-proof
Good thermal insulation
High compressive strength
close cell polyurethane pu foam for insulation spray
Component A: polyol
Component B: isocyanate
close cell polyurethane pu foam for insulation spray
When polyol and isocyanate (mdi) are mixed together using suitable foam spray equipment, the resulting foam has a homogenous density. Foams which are allowed to cure for a sufficient time between the layers applied have good skin formation and show good adhesion to the sprayed surface. Special care must be taken the sprayed surfaces are not cold or wet. It is mainly used for the insulation of wall&roof and cold room & container.
Component A is 220kg/iron drum;
Component B is 250kg/iron drum.
One set: 470 kg=220kg A+250kg B
One 20' container loads 40 sets/80 drums/18.8 tons
