Shanghai Daoqin Plastics Co., Ltd.

近段 time below/following, new type 冠状病毒肺炎疫情牵动 十几 100 million 人 心弦. 社会各界万众一心 is add 油, is China add 油.

in 疫情肆虐之际, large chemical industry enterprise 挺身而出, in has 硝烟 战场 upper, add add 点保障 anti 疫消毒 liquid, anti and raw materials and other material production, again 次显现出 chemical industry industry property function. medical grade plastics is this 场战役 in can important 一员. large to CT machine, 床边血 oxygen 仪, machine and other equipment, small to agent box/case, one-time property liquid device and other.

commonly used medical grade plastics has which? future development trend how to? 今天周 small and large 家聊聊 medical grade plastics that 事儿:

due to need and liquid or 人体接触, medical grade plastics basic requirements is tool has chemical stability property and material safety property. simple 说, plastics material in formed formed separation can 析出进入药 liquid or 人体, 不会引起组织 device 官 毒 property and loss 伤, for is 无毒无害. USA medical grade plastics usually through FDA certification and USPVI生 material testing, medical grade plastics usually related testing in testing.

use usually according to device products structure and strong/high degree requirements, selection combined plastics type type and grade, 并确定材 material processing process. this property can 包括 processing properties, force strong/high degree, use cost, assembly methods, can property and other.

PVC and PE use amount most large

commonly used medical grade plastics material large has types, polyethylene (PE) （PE）, polypropylene (PP) （PP）, polyvinyl chloride (PVC) （PVC）, polyurethane ester （PU）, PTFE （PTFE）, polycarbonate (PC) （PC）, polystyrene (PS) (PS) and other, PVC and PE use amount most large, 各占28% and 24%; PS占18%; PP占16%; engineering plastics 占14%.

commonly used types medical grade plastics has:

●  PVC:

据 market 估计, medical grade plastics product large 约25% is PVC. main/primary is due to resin cost relatively low, application scope vast, and its easy processing. application PVC product has: liquid tube/pipe 路, 呼吸面罩, oxygen tube/pipe and other.

●  PE:

usually can used for 针帽, injection device 推杆, liquid device amount adjustment device, liquid device and injection device packaging bag and other. its in UHDPE tool has relatively high impact strong/high degree, low friction property, resistant force cracking property and relatively good can features, make formed is 人造臀, cover/cap and connectors 理想材 material.

●  PP:

medical grade PP tool has relatively high transparent degree, relatively good retardant property and resistant property, make its in medical equipment and packaging upper tool has application. 以PP is Non-PVC材 material is currently use PVC材 material substitute/replace product.

●  PS:

质 hard 而脆, has relatively high thermal expansion coefficient, therefore, made it in engineering upper application. 近几十 year, development modified polystyrene (PS) and styrene is copolymer, in 一定程 degree upper polystyrene (PS) disadvantages. K resin is its in types.

●  ABS:

ABS in medical upper application main/primary used as outer tool, 滚筒夹子, plastics 针, tool box/case, diagnosis device parts and device outer housing/shell, especially is large type medical equipment outer housing/shell.

●  PC:

PC type features is tough property, strong/high degree, rigid property and heat resistant 蒸汽消毒, this features make PC excellent selection formed is liquid 渗析 滤 device, outer tool and oxygen gas 罐（当 in outer 科心脏手术 in, this type of device can remove liquid in oxidation carbon, increase oxygen gas ）; PC in upper application also 包括无针 injection system, 灌注仪 device, liquid machine and active 塞.

●  PTFE:

friction coefficient is plastics in most low, tool has good material versus property, can made as formed 人工血 tube/pipe and other 直接植入人体 device 械.

substitute/replace Imported large

full medical devices market 规模约5000 100 million USD; its in one-time property consumption device is 40%. Europe and other 发达国家 and 区, one-time property medical grade consumption sales already to its medical devices sales 总额 45%, 我国 占20%. from Imported 情况看, one-time property consumption Imported amount most more, 约占总 Imported amount semi.
