Eastman invented Eastman NPG™ glycol in the 1950s, and its market share continues to grow to this day. Eastman offers the broadest portfolio and global supply of high-performance monomer intermediates for resins, as well as additives, inhibitors, and copromoters. Eastman NPG™ is available in two forms: as white, waxy platelets or molten. A slurry of 90 percent by weight with water is available, and designated Eastman NPG™ 90.
Formulators and purchasers of intermediates for resins continue to find Eastman NPG™ glycol useful in new applications and new markets.
Applications where Eastman NPG™ glycol is useful are:
- Production of diesters and polyesters, where it provides fast processing, excellent stability, low color, good resistance to chemicals and weathering, and improved electrical, thermal, and hydrolytic stability
- Unsaturated polyester gel coats for marine applications and bathroom tubs, sinks, and toilets, where Eastman NPG™ imparts low color, excellent weathering, and hydrolytic stability
- Fiberglass-reinforced greenhouses and similar structures
- Halogenated, flame-retardant polyesters
- Saturated, reactive polyesters based on Eastman NPG™ combined with melamine resins to produce premium-quality heat-curable enamels for coil coating or spray applications
- Rigid and flexible polyurethane foams
