PA material features:

1.PA12 is from butadiene property, semi crystallization - crystallization thermoplastic property 材;

2.PA12 is very good electrical insulation and and its it polyamide (PA) 一;

3.PA12 has many in features and reinforcement features 方面 改良;

4.PA12 viscous property main/primary 取决于 wet degree, temperature degree and time;

5.PA66 in polyamide (PA) material in has relatively high melting point;

6.PA66 in relatively high temperature degree can maintain relatively strong/high strong/high degree and rigid degree;

PA chemical features:

1. PA12 is from butadiene property, semi crystallization - crystallization thermoplastic property material. it features and PA11 versus 似, 但晶体 structure different.

2. PA12 is very good electrical insulation and and its it polyamide (PA) 一样不会因潮 wet effect/influence insulation property can. it has very good impact resistant property machine chemical stability property.

3. PA12 has many in features and reinforcement features 方面 改良 product types. and PA6 and PA66 versus ratio, this material has relatively low melting point and density, tool has non high rate.

4. PA12 for strong/high oxidation property acid resistant can force.

5. PA12 viscous property main/primary 取决于 wet degree, temperature degree and time. it flow property very good. shrinkage rate in 0.5% to 2% between, this main/primary 取决于材 material product types, thick and its it process conditions.

6. PA66 in polyamide (PA) material in has relatively high melting point. it is types semi 晶体-晶体材 material.

7. PA66 in relatively high temperature degree can maintain relatively strong/high strong/high degree and rigid degree. PA66 in molding rear still tool has wet property, its degree main/primary 取决于材 material formed, thick and ring conditions 二, PA6 polyamide (PA) 6 or nylon 6

typical applications scope/range: due to has very good machine strong/high degree and rigid degree by used for structure parts. due to has very good wear resistant loss features, also used for manufacturing bearings. 2. injection molding process conditions:

drying 处理: due to PA6 very easy absorption water separation, therefore processing front drying especially need attention/notes. if material is use anti water material packaging supply, container maintain 密闭. if wet degree large 于0.2%, in 80C above hot gas in drying 16 small 时. if material already in gas in ultra- 8 small 时, 建议进行105C, 8 small above true dry.

熔化 temperature degree: 230~280C, for/regarding reinforcement product types is 250~280C.

mold temperature degree: 80~90C. mold temperature degree very significantly effect/influence crystallization degree, crystallization degree also effect/influence parts machine features. for/regarding structure parts crystallization degree very important, therefore mold temperature degree is 80~90C. for/regarding thin 壁, process/workflow relatively long parts 也建议施 use relatively high mold temperature degree. increase large mold temperature degree can improve/increase parts strong/high degree and rigid degree, reduce tough property. if thick large 于3mm, use 20~40C low temperature mold. for/regarding reinforcement material mold temperature degree large 于80C.

injection pressure: generally in 750~1250bar between （取决于材 material and product design ）. injection speed degree: high speed （ for reinforcement type material need micro reduce ）.
