Ultramid A3HG5是一種用25%玻璃纖維增強的聚酰胺66。它具有良好的彈性和介電性能、高尺寸穩定性、高蠕變強度和良好的滑動摩擦性能。它在低溫下提供良好的韌性、硬度、高剛度、高機械強度、剛度、熱穩定性、高耐熱老化性、非常好的沖擊強度和良好的加工性。它對化學品、熱潤滑劑和熱水、燃料、液壓流體和冷卻劑、制冷劑、染料、油漆、清潔劑、脫脂劑、脂族和芳香烴以及許多其他溶劑表現出良好的抵抗力。與許多無定形塑料相比，Ultramid A3HG5抗腐蝕、耐鹽和堿的水溶液以及耐應力裂紋形成。它是通過注射成型加工的。它適用于機械部件和外殼。它還用于線圈架、軸承保持架和電絕緣部件。

Ultramid A3HG5 is a polyamide 66 reinforced with 25% glass fiber. It possesses good elastic & dielectric properties, high dimensional stability, high creep strength and excellent sliding friction properties. It provides good toughness at low temperatures, hardness, high rigidity, high mechanical strength, stiffness, thermal stability, high heat-aging resistance, very good impact strength and good processability. It exhibits outstanding resistance to chemicals, hot lubricants and hot water, fuels, hydraulic fluids and coolants, refrigerants, dyes, paints, cleaners, degreasing agents, aliphatic and aromatic hydrocarbons and many other solvents. Ultramid A3HG5 is resistant to corrosion, to aqueous solutions of salts and alkalis and to stress-crack formation compared to many amorphous plastics. It is processed by injection molding. It is suitable for machinery components and housings. It is also used for coil formers, bearing cages and electrically insulating parts.
