Shanghai Daoqin Plastics Co., Ltd.

main/primary property 质:

1, appearance transparent, rigid hard belt/tape tough property. slow, rear slow 熄.

2, PC material resistant impact property is plastics in most good.

3, molding shrinkage small (0.5-0.7%), formed product degree high, dimensional stability high.

4, chemical stability property relatively good, resistant alkali, ketone, 芳香烃 and other has machine solvent agent.

5, resistant fatigue strong/high degree 差, for 缺口敏感, resistant force cracking property significantly.

molding process:

1, drying conditions: temperature degree 110-120℃, time 8-12 small 时.

2, flow property 差, must use high pressure injection molding, injection molding pressure high make product internal stress easy cracking.

3, PC material viscosity for temperature degree very 敏感, improve/increase temperature degree 时, viscosity has obvious decline.

4, mold design requirements relatively high.

5, injection speed degree fast, easy melt phenomenon, in gate 周围会 has 糊斑, product surface and other defect or gas defect (困 gas)而 make product 烧焦.

6, mold temperature control in 80-100℃ is 宜.

7, molding rear is decrease small internal stress, can using/adopting 退火处理.

typical applications scope/range:

PC engineering plastics large application areas is assembly 业, automotive industrial and electronics, electrical appliances industrial, its also has industrial machine parts, light 盘, packaging, machine and other office equipment, medical and 保健, film, and anti device and other. PC can used as 门窗玻璃, PC laminate used for 银行, 公共场 anti 护窗, used for machine 舱罩, lighting equipment, industrial safety sheet/plate and anti l elastic 玻璃.

PC sheet/plate can various 标牌, 如汽油泵 table/sheet 盘, automotive table/sheet sheet/plate, and 露天商业标牌, sliding device, PC resin used for automotive lighting system, table/sheet system and inner decoration system, used as front lamp covers, belt/tape add strong/high automotive front rear sheet/plate, light frame, frame sleeve/set, as sleeve/set, retardant sheet/plate, PC by application used as box/case, base/seat, and sleeve/set tube/pipe, sheet/slice, electrical 视转换 plant/unit, electrical 话线路支架 lower cable parts, electrical box/case, electrical machine, electrical parts, electrical appliances outer housing/shell, PC can low parts, used for use electrical appliances 马达, true 空吸尘 device, device, machine, 烤面包 machine, force tool 手柄, various gears, 蜗轮, sleeve/set, 导规, inner 搁架. PC is light 盘储存介质理想 材 material.
