Ultramid A3EG7是一種聚酰胺66增強(qiáng)材料，含有35% 玻璃纖維增強(qiáng)材料。該牌號(hào)在低溫下具有良好的韌性、硬度、高剛性、高機(jī)械強(qiáng)度、剛度、熱穩(wěn)定性、非常好的沖擊強(qiáng)度和良好的加工性能。它對(duì)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，它耐腐蝕、耐鹽和堿的水溶液以及應(yīng)力裂紋的形成。它具有良好的彈性和介電性能，高尺寸穩(wěn)定性，高蠕變強(qiáng)度和優(yōu)異的滑動(dòng)摩擦性能。它通過注塑成型加工。Ultramid A3EG7 適用于機(jī)械部件和外殼，例如燈座外殼、加熱泵、流量加熱器以及電絕緣部件。

Ultramid A3EG7 is a polyamide 66 reinforced with 35% glass fiber. This grade provides good toughness at low temperatures, hardness, high rigidity, high mechanical strength, stiffness, thermal stability, 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. It is resistant to corrosion, to aqueous solutions of salts and alkalis and to stress-crack formation compared to many amorphous plastics. It possesses good elastic & dielectric properties, high dimensional stability, high creep strength and excellent sliding friction properties. It is processed by injection molding. Ultramid A3EG7 is suitable for machinery components and housings such as lamp socket housings, heating pumps, flow heaters as well as electrically insulating parts.
