PSU plastics

(polysulfone (PSU))
英文名称:Polysulfone 　
specific gravity:1.25-1.35克/立方 cm molding shrinkage:0.5-0.7% molding temperature degree: 290-350℃ drying conditions: 130-150℃ 4 small 时
material material property can

1, polysulfone (PSU) is transparent solid material, hardness and impact strong/high degree high, 无毒, heat resistant resistant property resistant aging property good, can in -100--175 degree lower long use. resistant machine acid alkali salt 腐蚀, resistant 芳香烃 and 卤化烃. poly hardness high, resistant 辐射, heat resistant and resistant property good tool has property, can in -100-175 degree lower long use.
2, through glass fiber reinforcement modified can make material wear resistance large degree improve/increase.
3, can will polysulfone (PSU) and ABS, poly 酰亚氨, polyether ether ketone and fluorine plastics and other made formed polysulfone (PSU) modified product, main/primary is improve/increase its impact strong/high degree and elongation, resistant solvent agent property, resistant ring property can, processing properties and can electroplating property. 如PSF/PBT,PSF/ABS,PSF+矿 material powder.

applications

1, made as heat resistant parts, insulation parts, decrease abrasion wear resistant parts, device table/sheet parts and medical devices parts, poly 芳砜适于 made as low temperature as parts.
2, polysulfone (PSU) in electronics electrical appliances industrial used for manufacturing formed sheet/plate, tube/pipe 架, device, sleeve/set 架, electrical film, high property can alkali battery outer housing/shell.
3, polysulfone (PSU) in use electrical appliances used for micro 波烤炉 equipment, add hot device, wet lubricating device, machine, dry machine, material and food separation device and other. can has color metal used for table/sheet, machine, versus machine and other precision structural parts.
4, polysulfone (PSU) already through USA 医药, food field/area has specification, can 代替不锈钢 products. due to polysulfone (PSU) resistant gas, hydrolysis resistant, 无毒, high temperature resistance gas 消毒, high transparency, dimensional stability good and other features, can used as 手术工 tool 盘, device, control device, 心脏阀, device, anti tool, and other.
 

molding property can

1.无定形 material,吸 wet large, water absorption 0.2％-0.4％, use front must separation drying, anti again wet. ensure water amount in 0.1％ below/following.
2. plastics raw materials molding property can and PC versus 似, heat stabilized property 差, 360 degree 时开始出现 separation understanding.
3. flow property 差, cooling fast, use high temperature high pressure molding. mold has strong/high degree and rigid degree, cold material 井, runner short, gate dimensions parts thick 1/2-1/3
4. is decrease small injection molding products generate internal stress, mold temperature degree control in 100-140 degree. molding rear can 采取退火处理甘油浴退火处理, 160 degree, 1-5 separation 钟; or 采取空 gas 浴160 degree, 1-4 small 时. time 取决于 products large small and thick.
5. polysulfone (PSU) in melt lower 接近于牛顿体, similar poly carbon acid 脂, flow property for temperature degree comparison 敏感, in 310 degree -420 degree inner, temperature degree rise high 30 degree, flow property increase 1倍. molding main/primary through improve/increase temperature degree improvement processing flow property.
