透明尼龙PA12 (CAS No.None)
- 物化性质
- PA12是从丁二烯线性聚合得到的半结晶-结晶热塑性材料，特性与PA11相似但晶体结构不同。具有优良的电气绝缘性，且不受潮湿影响；抗冲击性和化学稳定性好。对强氧化性酸无抵抗能力。回潮率低，流动性好，收缩率在0.5%到2%之间，取决于材料品种、壁厚及工艺条件。密度约1.01~1.02 g/cm³，熔点约178~180°C。
- 技术参数
- 加工前应保证含水率在0.1%以下，建议在80°C除湿干燥4~8小时。 熔融温度240~300°C，普通特性材料不超过310°C，阻燃特性材料不超过270°C。

Product Name:Polyamide 12 (PA12)
English Name:Polyamide 12 (PA12)
CAS No.:25038-54-4
Aliases:Nylon 12, Polylaurolactam, PA12
Molecular Formula:(C12H23NO)n
Physical Properties:PA12 is a semi-crystalline to crystalline thermoplastic material derived from butadiene, with properties similar to PA11 but a different crystal structure. It has excellent electrical insulation properties unaffected by moisture, good impact resistance and chemical stability. It is not resistant to strong oxidizing acids. It has low moisture absorption, good flowability, and a shrinkage rate of 0.5% to 2%, depending on material grade, wall thickness and processing conditions. Density approx. 1.01-1.02 g/cm³, melting point approx. 178-180°C.
Uses:Used for water meters and other commercial equipment, cable sheathing, mechanical cams, sliding mechanisms, photovoltaic backsheets and bearings. Particularly suitable for noiseless gears in DVD, CD, MD, VCR, camcorders, digital cameras, printers and video recorders.
Technical Specifications:
Moisture content should be kept below 0.1% before processing; dehumidifying drying at 80°C for 4-8 hours is recommended.
Melt temperature 240-300°C; do not exceed 310°C for standard grades and 270°C for flame-retardant grades.
Barrel temperature: feed zone 230-240°C, middle zone 255-265°C, metering zone 265-275°C, nozzle 295-300°C.
Mold temperature 60-80°C, injection pressure 80-110MPa, cycle time 20-25 seconds, screw speed 30-60 r/min.
Shrinkage rate ranges from 0.5% to 2%, depending on material grade, wall thickness and processing conditions.
