Intumescent coatings swell when exposed to heat thus, increasing volume and decreasing density. These coating are typically used in passive fire protection. Nitrogen flame retardant solutions are part of the intumescent mechanism.
Delamin supplies Delaspheres™ (Cenospheres) and Delflam™ for this application.
click on the underlined headings below to see our full product range for this application.
Delaspheres™(Cenospheres) are small, high strength, extremely lightweight, free flowing, non porous, hollow ceramic spheres. Cenospheres are used primarily as lightweight fillers in the oil and gas, plastics, building, refractories, automotive, aerospace and surface coating industries. Delaspheres™ are available in both grey and white to suit the intended application.
Delflam™ is a range of zero halogen nitrogen flame retardant synergists manufactured from melamine resulting in homologues having higher thermal stability compared to pure melamine, melamine cyanurate and melamine polyphosphate. It is non-toxic and non-corrosive.
Delflam™ is the latest development in our Nitrogen Flame Retardant programme and has now replaced the Delacal™ range. Delflam™ consists mainly of melem with a minor proportion of melam.
