Polyketones (PK) are a specialized group of polymers with high impact resistance, chemical durability, and dimensional stability. They are thermoplastics based on repeating ketone units and are gaining popularity in automotive, industrial, and electronic industries due to their toughness and processability.Polyketones (PK) are a specialized group of polymers with high impact resistance, chemical durability, and dimensional stability.

• Automotive industry: Fuel tanks, valves, engine covers, and parts requiring chemical resistance and toughness.
• Industrial equipment: Pump parts, valves, gears, and housings in aggressive media.
• Electronics: Connectors, insulators, and housings needing electrical insulation and low moisture uptake.
• Consumer products: Tool components, sports equipment, and durable household goods.
• Exceptional impact resistance: Among the toughest thermoplastics, with excellent performance even at low temperatures.
• Good chemical resistance: Withstands fuels, oils, acids, and bases—suitable for a wide range of industrial applications.
• Low moisture absorption: Maintains stability and properties in humid environments.
• Easy processing: Suitable for fast injection molding with short cycles and high productivity.
• Eco
• friendly production: Often derived from CO₂ feedstock, reducing carbon footprint.
• Lower heat resistance: Not suitable for continuous use above 120 °C, unlike PBT or PA6.6.
• UV sensitivity: Requires stabilizers for outdoor use to prevent yellowing and degradation.
• Limited stiffness: Less rigid than other engineering plastics, limiting use in high
• stiffness applications.
