GrafGuard® 280-50N

Technical Datasheet | Supplied by NeoGraf Solutions
GrafGuard® 280-50N by NeoGraf Solutions is a lead- & chromium-free, non-halogenated, non-flammable, fire retardant additive. This expandable graphite flake offers customized onset temperature from 150 to 250°C, high expansion volume and high volume manufacturing capability. It forms an effective insulating char layer that protects the substrate from heat and oxygen. This non-toxic product exhibits superior performance at low temperatures, expands up to eight times more and enables ideal applications as an intumescent additive. It improves the performance of fire-retardant additives such as phosphates, magnesium hydroxide and nitrogen compounds. GrafGuard® 280-50N provides consistent engineered activation temperatures to meet compounding/processing requirements and controlled surface pH (4-9). Its performance does not degrade with time or environmental exposure and meets many flame-stop performance targets at low loading levels. It is compatible with any catalyst system and reduces smoke evolution. This additive is used in thermoplastics, polypropylene, polystyrene, PET, nylon and ABS. It is the material of choice for thermoformed and extruded thermoplastic panels used in the aerospace and automotive industries. It complies with REACH.
