C3U 改進(jìn)阻燃 低溫韌性 Ultramid 耐沖擊電氣絕緣部件應(yīng)用 

Ultramid C3U 是一種聚酰胺 6/66 等級(jí)，具有改進(jìn)的阻燃性。具有良好的彈性性能、尺寸穩(wěn)定性、低蠕變傾向和良好的滑動(dòng)摩擦性能。在低溫下具有良好的韌性、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。對(duì)化學(xué)品、潤(rùn)滑劑、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(wú)定形塑料相比，耐腐蝕、耐鹽堿水溶液以及應(yīng)力裂紋形成。通過(guò)注塑成型加工。用于觸點(diǎn)底座和插頭連接器條等耐沖擊電氣絕緣部件。

Ultramid C3U is a polyamide 6/66 grade with improved flame retardance. Possesses good elastic properties, dimensional stability, low tendency to creep and excellent sliding friction properties. Provides good toughness at low temperatures, high rigidity, high mechanical strength, stiffness, thermal stability, very good impact strength and good processability. Exhibits outstanding resistance to 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. Used for impact resistant electrical insulating parts such as contact bases and plug connector strips.
