Methylene diphenyl isocyanate (MDI) is an essential raw material used primarily to manufacture polyurethane foam used in a variety of products and industrial applications. Polymeric MDI is a technical grade mixture of diphenylmethane-4,4′-diisocyanate with isomer and homologues of higher functionality. It is used in system with polyols to produce rigid polyurethanes foam,and also in semi-rigid foam ,CASE application.
Key Benefits of Polymeric MDI:
• Superior Bonding Strength: Polymeric MDI creates a strong bond between chip foam particles, resulting in a more durable and cohesive final product.
• Improved Moisture Resistance: Polymeric MDI enhances the moisture resistance of chip foam, preventing degradation and extending product lifespan.
• Streamlined Production: Polymeric MDI often allows for faster curing times, leading to increased production efficiency.
• Reduced VOC Emissions: Some Polymeric MDI options boast lower VOC (volatile organic compound) emissions, contributing to a more environmentally friendly production process.
1. Drying. Nearly all gases and liquids can be dried with F-200. Water removal is often necessary for efficient processing, storage and transportation of fluids. The 3/16" size is normally recommended for vapor phase dehydration applications where pressure drop minimization yet high H2O adsorptive capacity is desired.
The 1/8" and 7 x 14 Tyler mesh sizes are recommended for use in liquid dehydration and other mass transfer limited adsorption applications.
BASF F-200 activated alumina is rapidly becoming the industry standard for drying compressed air. Providing long service life with performance at or below dew point specifications, F-200 is a 'peace of mind' product for both large and small dryers. BASF F-200 is appropriate for use in dehydrating
gases in both thermally regenerative (350 to 600°F) and pressure swing (PSA) modes.
2. Acid removal. Transformer oils, lubricating oils, and refrigerants form degradation acids upon use. BASF F-200 will remove these acids during use. In the manufacture of chlorinated and/or fluorinated hydrocarbons, removal of these residual halides and water is essential for a non- corrosive product.
3. Process stream purification. BASF F-200 is excellent for removal of highly polar compounds such as water and alcohol. It also readily adsorbs TBC ad heavy metal ions from hydrocarbons.
4. Hydrocarbon adsorption. Under proper operating conditions, the pore size distributions and surface chemistry of activated aluminas are conducive to the adsorption of hydrocarbons.
