Ultramid A3K FC 是一種聚酰胺 66 級。具有良好的彈性性能、尺寸穩定性、低蠕變傾向和良好的滑動摩擦性能。在低溫下具有良好的韌性、良好的流動性、高剛性、硬度、高機械強度、剛度、熱穩定性、非常好的沖擊強度和良好的加工性能。具有出色的奈磨性、耐化學品、耐潤滑劑、耐燃料、液壓油和冷卻劑、制冷劑、染料、油漆、清潔劑、脫脂劑、脂肪族和芳烴以及許多其他溶劑。與許多無定形塑料相比，耐腐蝕、耐鹽堿水溶液和應力裂紋形成。通過注塑成型加工，適用于食品接觸應用。

Ultramid A3K FC is a polyamide 66 grade. Possesses good elastic properties, dimensional stability, low tendency to creep and excellent sliding friction properties. Provides good toughness at low temperatures, good flow, high rigidity, hardness, high mechanical strength, stiffness, thermal stability, very good impact strength and good processability. Exhibits outstanding resistance to abrasion, chemicals, lubricants, fuels, hydraulic fluids and coolants, refrigerants, dyes, paints, cleaners, degreasing agents, aliphatic and aromatic hydrocarbons and many other solvents. Is resistant to corrosion, to aqueous solutions of salts and alkalis and to stress-crack formation compared to many amorphous plastics. Processed by injection molding and is intended for food contact applications.
