The Lubrizol Corporation has announced the commercial availability of a novel flame retardant product, Hycar® NH3069, designed to deliver excellent flame retardant performance without the use of additives or halogenated materials.
Hycar® NH3069
Based on new, self-crosslinking, non-halogen polymer technology, Hycar® NH3069 imparts flame retardancy to cellulosics, making it a powerful protective technology for paper, cotton, rayon, glass and mixed fiber media applications.
In addition to flame retardant benefits, Hycar® NH3069 offers excellent mechanical performance and improved clarity compared to particulate-filled coatings. Its inherent thermal stability during processing provides improved color over halogenated polymers.
With less additives required, reduced mixing, less chemical inventories and faster clean-up are possible, resulting in higher manufacturing productivity. For filtration applications, Hycar® NH3069 provides a lower pressure drop compared to particulate additives.
Technology Avoids the Need for Heavy Metals
"This new and unique, halogen-free polymer technology from Lubrizol avoids the need for heavy metals, like antimony trioxide" notes Gary Anderle, marketing manager. "It's a game changer for many applications, and we look forward to exploring its full potential by collaborating with formulators to achieve specific flame retardance needs."
Hycar® NH3069 is part of an exciting new platform that will evolve into future flame-retardant products. It can be applied using a broad range of techniques, including knife coatings (J-box), dip and squeeze (padding), foam, gravure, screen printing and rod coating.
