PA12 Scientific Names is poly inner amine, also nylon 12. its polymerization basic raw materials is butadiene, can 依赖于石油 chemical industry. is semi crystallization - crystallization thermoplastic property material. it features and PA11 versus 似, 但晶体 structure different. 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.

and PA6 and PA66 versus ratio, this material has relatively low melting point and density, tool has non high rate. USA DuPont PA12 for strong/high oxidation property acid resistant can force. 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 PA12 polyamide (PA) 12 or nylon 12.

water amount table/sheet and other equipment, cable sleeve/set, machine 械凸轮, sliding machine and bearings and other.

PA12 is from butadiene property, semi crystallization - crystallization thermoplastic property material. it features and PA11 versus 似, 但晶体 structure different. 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. 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. PA12 for strong/high oxidation property acid resistant can force. 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.

drying 处理: processing front ensure wet degree in 0.1% below/following. if material is in gas in 储存, need in 85℃ hot gas in drying 4~5 small 时. if material is in container in 储存, that 么经 3 small temperature degree balanced can use.

熔 melt temperature degree:240~300℃; for/regarding features material need ultra- 310℃, for/regarding has flame retardant features material need ultra- 270℃.

high speed injection speed degree can make molding good.

PA12 nylon 12 elastomer has excellent 良 噪音 and retardant property, in drying conditions lower, for 钢, POM, PBT and other material sliding friction coefficient low, excellent wear resistant loss property and high stability property. positive is this property 质, product especially suitable for DVD, CD, MD, VCR, 便携式摄像 machine, versus machine, printing machine and machine and other gears.

进 material 段:230-240℃

说明:1.若充模不满: improve/increase temperature degree 10-15℃, need improve/increase injection molding pressure and speed degree, generate water 花;

2.若塑 parts 发白起雾:请 improve/increase material temperature degree 10-15℃, pressure 70-100mpa, speed degree in speed, make gas good;

3.若 mold sticking or 者变黄 color:请 reduce temperature degree 10-15℃, reduce injection molding pressure and speed degree;

4.烁斑 solution methods:系数 low, excellent wear resistant loss property and high stability property. positive is this property 质, product especially suitable for DVD, CD, MD, VCR, 便携式摄像 machine, versus machine, printing machine and machine and other gears.
