NEW Everpol MEG-380 AMG Initiated Polyether Polyol from Everchem
March 21, 2024
EVERPOL MEG-380 is an Alpha Methyl Glucoside-initiated polyether polyol polymerized with propylene oxide. The resulting material has a functionality of four and a typical hydroxl of 380. Due to the higher percentage of carbohydrate moieties when compared with sucrose carbohydrates on a similar weight basis, MEG-380 provides enhanced foam charring with improved compression sets. Main applications include low to high density rigid pour-in-place systems, however, EVERPOL MEG-380 may also be included as a component in flexible polyurethane foam formulations to build bio-content.
OVER 25% BIO-BASED | CHAR ENHANCER | 4-FUNCTIONALITY
Everchem has developed a new polyether polyol in conjunction with one of our long-term production partners that will provide unique advantages to your polyurethane formulation challenges.
EVERPOL MEG-380 Benefits:
- – Over 25% Bio Content as Alpha Methyl Glucoside (AMG) carbohydrate to meet the Certi-PUR Bio-Certification program.
- – AMG does not decompose like sugar carbohydrates during the polyol manufacturing process.
- – Improved compression sets with 4-functional structure.
- – Lower viscosity when compared with sugar polyols at similar carbohydrate loading.
- – Char enhancer with a higher percentage of carbohydrate moieties compared with sucrose carbohydrates on a similar weight basis.
EVERPOL MEG-380 Market Applications:
- – Low Density Rigid Systems with high water content – SPF, FIP packaging
- – High Density Rigid Systems with low level Aux Blowing Agents.
- – High Density Flexible Foam grades AND High Density Visco-Foam grades with high Bio-Content demands.
