Usage

Polyurethane raw material pure MDI is mainly used in slurry, sole stock solution, spandex, TPU and other fields

Polymeric MDIcan be widely used in the manufacture of rigid polyurethane foam insulation materials; it can also be used in isocyanurate foam, coatings, adhesives, anti-seepage and plugging, structural foam, microcellular integral skin foam, automobile insurance Bars, interior parts, high resilience foam, synthetic wood, and other fields. Due to its unique composition and structure, it has good foam flow performance and is also suitable for the manufacture of products that have strict requirements on the flow performance of the foaming stock solution.

Handling and storage

Since WANNATE® PM-200 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-200 should be kept properly closed and stored indoors at ambient temperature (15-35ºC) in a well-ventilated area. Storage at low temperature (below 5ºC) may lead to some crystallization; this material must, therefore, be protected from frost.
  If crystallization does occur, the material should be heated by rolling the drum in a hot air oven at 70-80ºC to melt it out, and should then be thoroughly agitated before use. Melting in a water bath is not recommended.
Extended storage at temperatures above 50ºC is not recommended to prevent from the formation of insoluble solids and viscosity increase.

Shelf Life
  Under recommended storage conditions, the shelf life of WANNATE® PM-200 is one year since the date of production.
