Ultramid A3WG6是一種由30%玻璃纖維增強的聚酰胺66。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、非常好的沖擊強度和良好的加工性。該等級對化學品、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、脂肪烴和芳香烴以及許多其他溶劑具有良好的抵抗力。它具有良好的彈性性能、高尺寸穩定性、高蠕變強度和良好的滑動摩擦性能。與許多無定形塑料相比，它耐熱老化、抗腐蝕、耐鹽和堿的水溶液以及耐應力裂紋形成。A3WG6是通過注射成型進行加工的。它用于機械部件和外殼，如燈座外殼、冷卻風扇、鋁窗框的絕緣型材以及不同的汽車動力總成零件。

Ultramid A3WG6 is a polyamide 66 reinforced with 30% glass fiber. It provides good toughness at low temperatures, hardness, high rigidity, high mechanical strength, stiffness, thermal stability, very good impact strength and good processability. This grade 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. It possesses good elastic properties, high dimensional stability, high creep strength and excellent sliding friction properties. It is resistant to heat aging, corrosion, to aqueous solutions of salts and alkalis and to stress-crack formation compared to many amorphous plastics. A3WG6 is processed by injection molding. It is used for machinery components and housings such as lamp socket housings, cooling fans, insulating profile for aluminum window frames, and different automotive powertrain parts.
