AvaSpire® AV-621 GF30 BK95

Technical Datasheet | Supplied by Solvay
AvaSpire® AV-621 GF30 BK95 is a black colored, flame retardant polyaryletherketones (PAEK) grade reinforced with 30% glass fiber. Is suitable for processing by injection molding, profile extrusion and machining. Offers good chemical resistance, low melt flow, long term thermal oxidative stability, high strength, high stiffness, high heat resistance, excellent colorability, improved ductility and toughness. Exhibits better dimensional stability, better warp resistance and lower heat deflection temperature than 30% carbon fiber reinforced PEEK grade, 20% higher tensile elongation at yield and twice the tensile elongation at break value when compared to PEEK grades. Used in healthcare/medical applications, transportation, electronics, oil and gas industry and chemical processing.
