Polymeric MDI BASF Lupranate M20S Made In China Used As Polyurethane Foam

1. Characteristics of Product

Polymeric MDI BASF Lupranate M20S is a solvent-free product based on 4,4'-diphenylmethane diisocyanate (MDI) containing oligomers of high functionality and isomers. The average functionality is 2.7.

2. Product Application

Polymeric MDI BASF Lupranate M20S is principally used for the manufacture of insulating foams and higher density rigid foams. It is also used for the production of semi-rigid foams in the automotive industry and sound insulation as well as for packaging foams, casting materials, binders and adhesives.

Panels for buildings
Spray heat insulation
Refrigerators
Automobile interior material

4. Product Packaging

Polymeric MDI BASF Lupranate M20S uses 250kg drum package or bulk supply.

5. Storage

Polymeric MDI BASF Lupranate M20S must be protected from moisture. The ideal storage temperature is 20 to 25 °C. Under these conditions and when moisture is excluded, the shelf life of Polymeric MDI BASF Lupranate M20S is at least six months. Drums must be kept airtight. In storage tanks the product should be kept under a dry nitrogen blanket. Longer storage leads to a lasting increase of viscosity depending on the temperature. In extreme cases a precipitate may form which will not be removed by heating. If the product becomes cold the viscosity will increase. This may lead to problems in processing. Storage for longer periods below 0 °C can lead to partial crystallisation. Crystallised material must be melted out immediately by short term heating. The product temperature must not exceed 70 °C. Localised overheating must be avoided, as Polymeric MDI BASF Lupranate M20S will decompose with the formation of gas at temperatures above 230 °C. Rolling of the drums in a hot air oven is the recommended method of dissolving the crystals. After melting out, the contents of the drum must be thoroughly mixed.
