A3WG5 UN 25玻纖增強 良好彈性PA66 Ultramid 機械部件 

Ultramid A3WG5 UNCOLORED是一種聚酰胺66，含有25% 玻璃纖維增強材料。它具有良好的彈性性能、高尺寸穩(wěn)定性、高蠕變強度和良好的滑動摩擦性能。該牌號在低溫下具有良好的韌性、硬度、高剛性、高機械強度、剛度、熱穩(wěn)定性、良好的沖擊強度和良好的加工性能。Ultramid A3WG5 UNCOLORED 對化學(xué)品、熱潤滑劑和熱水、燃料、液壓油和冷卻劑、制冷劑、染料、油漆、清潔劑、脫脂劑、脂肪族和芳香族烴以及許多其他溶劑具有出色的耐受性。與許多無定形塑料相比，它具有耐熱老化、耐腐蝕、耐鹽和堿水溶液以及應(yīng)力裂紋形成的能力。它通過注塑成型加工。它用于機械部件和軸承座，如線圈成型機和軸承保持架。

Ultramid A3WG5 UNCOLORED is a polyamide 66 reinforced with 25% glass fiber. It possesses good elastic properties, high dimensional stability, high creep strength and excellent sliding friction properties. This grade provides good toughness at low temperatures, hardness, high rigidity, high mechanical strength, stiffness, thermal stability, very good impact strength and good processability. Ultramid A3WG5 UNCOLORED 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 is resistant to heat aging, 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 used for machinery components and housings such as coil formers and bearing cages.
