Product Description

WANNATE® PM-400
Wannate® Pm-200 Diisocyanate-Diphenylmethane (MDI) Polymeric Mdi Pm400 From China Application
WANNATE® PM-400 is high functionality, high viscosity isocyanate which has a functionality of 2.8~2.9. It can be used the production of rigid PU foam  and polyisocyanurate foams; particularly fit for continuous production of laminated polyisocyanurate slabstock foams. WANNATE® PM-400 can improve cell homogeneity and dimensional stability of foams and the compressive strength vertical to the foaming direction. The flame retardancy of polyurethane and polyisocyanurate foams also shows some improvement.

Typical physical and chemical properties


Item(s)
Specification(s)
Appearance Brown Liquid
Viscosity   at 25 ºC ,   mPa •   s 350~500
-NCO, %Wt 30.5~32.0
Specific gravity at 25 ºC , g/cm 3 1.220 ~ 1.250
Acidity ( HCI ) , % ≤ 0.05
Hydrolysable Chlorine, % ≤ 0.2

Storage(s)
Since   WANNATE ®   PM-400   is  a reactive chemical, reaction with atmospheric moisture happens easily and leads   to  the formation   of  insoluble ureas and carbon dioxide gas, which can result   in  pressure build-up   in  closed containers and viscosity increase   of  the product. Containers   must   therefore   be  absolutely dry and carefully sealed after congested with nitrogen.

Containers of   WANNATE ®   PM-400 should be kept properly closed and stored indoors   at   ambient temperature (15~35 ºC )   in   a well-ventilated area. Storage   at low   temperature (below 0 ºC )   may   lead   to   some   crystallization; this material must, therefore,   be   protected from frost. If crystallization does occur, the material should   be   heated to 70-80 ºC   to   melt it   out, and   should   then be thoroughly agitated before use.
Extended storage at temperatures above 50 ºC   is not recommended to prevent from the formation of insoluble solids and viscosity increase.
