AvaSpire® AV-621 CF30

Technical Datasheet | Supplied by Solvay
AvaSpire® AV-621 CF30 is a black colored, flame retardant polyaryletherketones (PAEK) grade reinforced with 30% carbon fiber. Is suitable for processing by injection molding, profile extrusion and machining. Offers excellent chemical resistance, low melt flow, long term thermal oxidative stability, high heat resistance, excellent colorability, improved ductility and toughness. Exhibits better dimensional stability and warp resistance 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. AV-621 CF30 grade offers the highest strength, stiffness and fatigue resistance of any AV-621 based grades. Used in healthcare/medical applications, pump parts, seals, transportation, electronics and chemical processing.
