Chemlon® 66GS8HPolyamide 66Chem Polymer公司40% 玻璃珠产品说明：66GS8H is a 40% glass-sphere filled, heat stabilised injection moulding grade of nylon 66. It has lower differential shrinkage and warpage and so is often suitable for use in applications re greater dimensional accuracy.物性信息：基本信息填料/增强材料玻璃珠, 40% 填料按重量特性尺寸稳定性良好低翘曲性热稳定性收缩性低加工方法注射成型物理性能干燥调节后的单位制测试方法密度1.44--g/cm³ISO 1183收缩率 10.90 到 1.5--%内部方法机械性能干燥调节后的单位制测试方法拉伸模量63003200MPaISO 527-2拉伸应力 (断裂)90.045.0MPaISO 527-2弯曲模量50002300MPaISO 178弯曲应力 215575.0MPaISO 178冲击性能干燥调节后的单位制测试方法简支梁缺口冲击强度5.08.0kJ/m²ISO 179热性能干燥调节后的单位制测试方法热变形温度 0.45 MPa, 未退火> 240235°CISO 75-2/B 1.8 MPa, 未退火220180°CISO 75-2/A电气性能干燥调节后的单位制测试方法表面电阻率1.0E+141.0E+11ohmsIEC 60093体积电阻率1.0E+161.0E+14ohms·cmIEC 60093介电强度 (3.00 mm)1513kV/mmIEC 60243-1耗散因数 (1 MHz)0.0200.080IEC 60250可燃性干燥调节后的单位制测试方法UL 阻燃等级HB--内部方法灼热丝易燃指数 (1.50 mm)650--°CIEC 极限氧指数27--%ISO 4589-2注射干燥单位制干燥温度80.0 到 100°C干燥时间2.0hr料筒后部温度270 到 290°C料筒中部温度270 到 290°C料筒前部温度270 到 290°C加工（熔体）温度< 300°C模具温度60.0 到 80.0°C注射速度快速螺杆转速50 到 200rpm注射说明背压：低注射压力：高如果材料在空气中暴露的时间不超过3小时，则无需干燥。1 .Mould shrinkage is significantly influenced by many factors including wall thickness, gating, component shape and moulding conditions.The range values stated were determined from specimen bar mouldings of 1.5mm to 4mm wall thickness. They are provided as a guide for comparison purposes only and no guarantee should be inferred from their inclusion. (Specimens measured in the dry state, 24 hours after moulding).2 .Break
