我需要PC/ABS樹脂的降伏強度範圍和降伏點和彈性係數(楊氏係數)和浦松氏比和密度等等這些機械性質的實驗數據(而不是介紹喔)
數據儘量給SI制或公制(KG~MPA~PA都可以)
謝謝~
有越完整的數據資料越好~奉上20點
(做專題用)

列兩種性質數據，請參考
(一)
PC/ABS樹脂510G PC/ABS Alloy的性質數據
物理性質
密度Density = 1.16 g/cc (ASTM D792)
Melt Flow = 5.5g/10 min (ASTM D1238)
機械性質
降伏強度 Tensile Strength, Yield = 56 MPa (ASTM D638)
Elongation at Break = 125% (ASTM D638)
Flexural Modulus = 2.31GPa (ASTM D790)
Izod Impact, Notched =5.9 J/cm (ASTM D256)
熱性質
Deflection Temperature at 0.46 MPa = 110°C (Annealed; ASTM Data)
Deflection Temperature at 0.46 MPa =113°C (Unannealed; ASTM Data)
Vicat Softening Point =113°C (ASTM D1525)
Flammability, UL94= HB， (1.5 mm)
(二)
MRC Polymers NAXALOY™ 750 PC/ABS Blend的性質數據
物理性質
Physical Properties
Density=1.13 g/cc (ASTM D792)
Water Absorption =0.15% (ASTM D570)
Linear Mold Shrinkage = 0.005 - 0.007cm/cm (ASTM D955)
Melt Flow = 4g/10 min (230°C/3.8 kg; ASTM D1238)
機械性質
Hardness, Rockwell R=115 (ASTM D785)
Tensile Strength, Yield = 55MPa (ASTM D638)
Elongation at Break = 30% (ASTM D638)
Flexural Modulus = 2.345GPa (ASTM D790)
Flexural Yield Strength = 86MPa (ASTM D790)
Izod Impact, Notched = 4.81J/cm (ASTM D256)
Impact Test = 52J (Instrumented dart impact; -10°F; Ductile break; ASTM D3763)
熱性質
Deflection Temperature at 1.8 MPa =110 C (ASTM D648)
製程數據
Processing Temperature = 260 - 282 C
Rear Barrel Temperature = 249 - 271 C
Middle Barrel Temperature = 260 - 277 C
Front Barrel Temperature = 271 - 282 C
Nozzle Temperature = 260 - 282 C
Mold Temperature = 49 - 82 C
Drying Temperature = 110 C
Dry Time = 4 hour
Moisture Content = Max 0.02%
Dew Point = Max -17.8 C
Drying Air Flow Rate = 22.7– 28.3 liter/min = 0.8 – 1 CFM (每小時生產一磅樹脂)
Injection Pressure = 68.9 – 138 MPa
Back Pressure = 0.345 –0.689 MPa
Cushion = 0.33– 0.635cm
Screw Speed = 40 – 70 rpm
其他性質
Fill Rate = Slow – Moderate
Hold Pressure = 40 - 60% of injection pressure
Packing Pressure = 50 - 75% of injection pressure
只貼得下兩個

每個廠商，每種產品，秘方不同，性質亦異，
降伏強度範圍，楊氏係數 和浦松氏比 都沒看到。
