Shanghai Daoqin Plastics Co., Ltd.

         low 游离(LF) technology can used for production 游离异氰 acid ester mono weight content low 于0.1% polyurethane ester (PU)预 poly 体. therefore, low 游离预 poly 体不受 Europe will 出台 二异氰 acid ester made effect/influence, and can front use 而不会 has new made. this has coating material, bonding agent and agent system processing and use 户, and elastomer parts production 商.

        2018 year 5 month, Europe chemical product tube/pipe 理局(ECHA)提交 about/regarding 二异氰 acid ester made plan 意见书. can 预见欧盟 will in future several month inner through this has 关健康保护 提议 strip/profile 例. tube/pipe about/regarding measures various fine and time table/sheet still has many 悬而未决 issues, very obvious, this made will for as and as process generate heavy large effect/influence. 总之, upper made will suitable for 处理基础 二异氰 acid ester, 例如MDI(二苯基甲烷二异氰 acid ester), TDI(甲苯二异氰 acid ester) or HDI(己二异氰 acid ester), and 游离二异氰 acid ester mono weight content ultra- 0.1% 传统 di separation PU system and PU预 poly 体.

         complex certification

         upper made 程序规定 旨 in improvement safety and 职业健康 tool has force can technology measures. most important is, company must for 含二异氰 acid ester material safety and use for 员工进行 training, provide certificate 形式 证明. 允许经 certification use this material. training especially complex, is 随 接触程 degree increase, training inner 容会越 越广泛, and must year heavy new certification one-time {图1}. PU industry 整 价 value in has 500万员工会受 to effect/influence —— from manufacturing and Imported to system material factory, formulation design and processing 商.

         new made effect/influence has PU technology. 例如, new strip/profile made 包括PU dispersion 体, hot active 化异氰 acid ester poly and thermoplastic polyurethane (TPU) (TPU). 游离二异氰 acid ester weight content low 于0.1% reaction system 同样不受 new strip/profile 例 限 made.

        寻找 substitute/replace material

         upper made expected in to year 渡期之 rear 才会实施, 以便由ISOPA(Europe 二异氰 acid ester and more alcohol production 商协会) and ALIPA(Europe aliphatic acid ester production 商协会) and other PU industry can development meet/satisfy strip/profile requirements 基础设施. however, LANXESS polyurethane ester system business 部观察 to many already 经面临 new requirements, in tool has most industrial solutions and can can substitute/replace product, 以便无需 a large amount of training and technology equipment investment can achieve 职业健康 and safety, according to new made specification, this training and investment can less.

        提 pure steps decrease/reduce poly in 游离二异氰 acid ester content

         LANXESS Adiprene low 游离预 poly is non combined substitute/replace material, it can most large degree decrease/reduce for 游离异氰 acid ester 接触, from 而避免受 to new made effect/influence. this material using/adopting low technology made formed, 游离二异氰 acid ester weight content low 于0.1%. 首先进行 addition polymerization reaction formed poly 体, rear 立即进行 true 空蒸馏, from to this type of non low content. 蒸馏工序 will reaction 二异氰 acid ester mono and poly separation 离. technology can used for various 二异氰 acid ester poly 体, 包括MDI基 system. due to 残留 游离二异氰 acid ester content small 于0.1%, therefore this low 游离预 poly by type is product, and 避免 各自 label requirements.

         adjustment versus separation and viscosity

        Adiprene low 游离预 poly in 健康, ring 境保护, industrial and safety tool has advantages. remove outer, and similar type poly versus ratio, it also can production technology upper property can more high PU终端 product. this is is use low technology can more control polymer 形态{图2}. this make crystallization hard and 无定形 soft between formed high degree 规整化 versus separation 离, from make PU product tool has more good material and mechanical properties. 例如, PU system can by made formed tool has high elastic property, resistant property and high tensile strength system, in addition also can obtain more narrow molecular weight distribution and more obvious material crosslinked. poly in 恒定 异氰 acid ester content (NCO content) lower viscosity has significantly 差异, can processing conditions, equipment and product property can. for/regarding coating system, can using/adopting this type of methods optimization coating lubricating wet property can and cover/cap rate.

         remove outer, Adiprene low 游离预 poly low viscosity make in its polymer upper increase chemical can degree formed is can can. this increase formed PU polymer property can and features. processing properties to improvement: low 游离预 poly and PU product can using/adopting more stability safety process separation production.

        广泛 low 游离预 poly product series

         LANXESS polyurethane ester system business in made 化PU system and 特定应

         use PU system development and made 方面拥 has 60 more year experience. company is 唯一一家 can provide multiple chemical product low 游离预 poly 体(二异氰 acid ester weight content low 于0.1%) manufacturing 商. not only TDI and MDI used for made low 游离预 poly 体, but also can use 脂族异氰 acid ester, 例如HDI and IPDI(异佛尔 ketone 二异氰 acid ester), it usually used for lightfast and weather resistant PU bonding agent and agent, meanwhile pPDI(for 亚苯基二异氰 acid ester) used for manufacturing 暴露于 high temperature and chemical product in PU elastomer. low 游离预 poly full range polyether, polyester, polycarbonate (PC) and poly inner ester more alcohol made formed. in addition, multiple alcohol and amine can use solid agent. this is manufacturing provide large active property, make its can optimization product processing conditions and material 理, heat resistant and chemical resistance can. LANXESS polyurethane ester system business its comprehensive 客户服务 and full has main/primary 经济区域 application development in 心 专业人员 is manufacturing provide full force 支持.

        CAS application is 受益

         using/adopting Adiprene low 游离预 poly has machine 会不受 new made effect/influence, this can significantly understanding coating material, bonding agent and agent industry (CAS) production and use pressure. reaction property hot bonding agent is very good 例子. due to use 期间会 use high temperature, this type of type type system 往往会 will more more 游离二异氰 acid ester mono 体释放 to as ring in. use Adiprene low 游离预 poly can will material 质 排放 amount drop most low. automotive manufacturing currently for mono content relatively low CAS材 material solutions especially performance large 兴趣. 他们希望避免 for 员工进行 a large amount of training, 并明确关注危险 grade relatively low product solutions.

         lower generation low 排放LFMDI预 poly 体

         LANXESS polyurethane ester system business will 自身定位 is will technology and tube/pipe trend and made 化PU system and related raw materials R&D versus combined solutions provide 商. business already 经开始 in new made process stage/phase optimization its low technology, therefore in can use has 二异氰 acid ester 基础材 material production 二异氰 acid ester mono weight content low 于0.1% 预 poly 体. its is versus 应 转变 low 游离预 poly 体 整 product series. 基于MDI low 游离预 poly 体持续 in more new breakthrough, this type of poly is can is many CAS application belt/tape heavy large key/critical 组份{图3}. AdipreneLFMDI预 poly viscosity relatively low, therefore 无需添 add dilute agent. this type of material made reaction property hot bonding agent tool has relatively high bonding strong/high degree and good flow property and lubricating wet property.
