Shanghai Daoqin Plastics Co., Ltd.

         LANXESS is construction industry development new generation polyurethane ester poly material. low 游离(LF) technology can used for production construction 业游离异氰 acid ester mono content low new MDI polyurethane ester (PU)预 poly material, its in 游离异氰 acid ester content small 于0.10%. therefore, this LF MDI预 poly material in safety and industrial 卫生方面符 combined standards, can low grade 别. most application focus/key point is bonding agent and agent and 1K foam.

         construction industry currently positive in 经历一场彻底 变革. construction material energy saving, resistant use, can recycled and for 健康没 has effect/influence material made formed. future trend 包括智 can 家居, block 化构建 and construction parts 3D printing. LANXESS polyurethane ester system business positive in solution this development issues. year, company is construction industry combined as 伙伴, plastics film product, 砖石裂缝密封, various sheet/plate coating and type thermal insulation.

         full property and R&D long

         through acquisition poly 亚, LANXESS will polyurethane ester combined business is enterprise business 部门. it will 自己视 is full polyurethane ester industry system supply 商. it is 铸造, coating, bonding agent and agent application provide 完整 组 combined formulation. polyurethane ester combined is world 领先 常规 and low 游离预 poly material and water property specialty polyurethane ester dispersion 体(PUD) supply 商之一, especially long solvent agent and LF mono system. it in full 球例如 Brazil, USA, China, Italy and UK has production 设施. its full research, development and innovation in 心位于康涅狄格州 Naugatuck. most 近Naugatuck development use ε- caprolactam new poly material. it can used for made mono separation, easy processing reaction system.

        预 poly material is property can key/critical

        另一项 innovation is is construction industry development new generation poly material, its 游离异氰 acid ester mono content low. it 们以Adiprene LF product sales, main/primary used for reaction property hot bonding agent, ring temperature degree lower drying bonding agent, agent and mono separation foam (1K).

        基于LF预 poly material bonding agent and agent can is industrial provide most 佳卫生 conditions LF technology will 广泛 异氰 acid ester, 包括MDI and other poly material in 游离异氰 acid ester concentrated degree reduce low 于0.10%. this 导致预 poly material structure mono and most product meet/satisfy relatively low and other grade and most new tube/pipe trend requirements. production can in production process in remove has high concentrated degree has 害异氰 acid ester raw materials, reduce 健康, safety and ring 境保护 technology and tube/pipe use, improvement industrial 卫生.

         high degree has structure

        LF异氰 acid ester poly material use make made polyurethane ester product tool has excellent property can. LF预 poly material 主导 形态变化, make material property can made, and meanwhile has processing property. in addition, it molecular weight distribution non in, reinforcement material crosslinked and hard and soft between high degree structure versus separation 离(图2). more versus separation improvement material material and mechanical properties. 例如, use LF预 poly material technology made PU system can performance excellent flexibility property and strong/high degree, meanwhile still maintain high tensile strength. this in tool has high machine negative and long lifespan application in to 体现.

        异氰 acid ester content 恒定, viscosity can 调

         through use LF technology, can control poly material viscosity. this is Adiprene LF main/primary advantages. poly material viscosity can made meet/satisfy has processing conditions and equipment, meanwhile meet/satisfy or ultra- application requirements can 恒定 异氰 acid ester content (NCO content) through control can large scope/range viscosity. this can for application optimization important product property (例如 lubricating wet is or cover/cap rate). has poly material can can need more high viscosity, its and agent 一起转化 formed foam. also or is in hot bonding agent in, low viscosity usually has 利于预 poly material and most system processing.

        基于MDI(亚甲基二苯基二异氰 acid ester) and poly alcohol LF预 poly material show/display viscosity how to 变化. this system non suitable for production mono separation foam. polyurethane ester combined can made types poly material system, its viscosity is 约50,000 MPa * s, 9,000 MPa * s and 约 6,000 MPa * s(50°C), solid 定NCO content is 6%. viscosity versus for in 100°C wide temperature degree scope/range inner maintain 恒定.

         used for hot melt adhesive LF预 poly material tool has high crystallization degree more alcohol

        LF预 poly material low viscosity in reaction property hot bonding agent reaction system in tool has 益处. it usually poly material made formed. poly material tool has polymer/macromolecule amount fast crystallization polyester more alcohol formed. PU polymer cooling 期间 早期 crystallization ensure bonding agent system high bonding strong/high degree. make use solid crystallization polyester more alcohol, LF technology still can used for made easy in low temperature lower processing bonding agent system poly material. it in low temperature lower also performance good lubricating wet property and flow property, and relatively low viscous property.

         polyurethane ester combined development 基于MDI LF预 poly material is its in 一 例子. its 自由NCO content low 于0.10%, and viscosity low, therefore made reaction property hot bonding agent system 而无需 dilute additives.

        “ filling good construction sleeve/set parts ”

         remove solid agent and additives outer, polyurethane ester combined also provide multiple acid ester and more alcohol, can according to block design 原则定 made low NCO content LF预 poly material, industrial processing mono separation foam, can in ring temperature degree or wet ring lower solid 化 现场施工 sealant. remove LF MDI and LF TDI预 poly material outer, polyurethane ester formulation also sales aliphatic LF HDI(六亚甲基二异氰 acid ester) and LF IPDI(异佛尔 ketone 二异氰 acid ester)预 poly material, can production light stabilization and weather resistant bonding agent and agent. 另一 关注 focus/key point is series need in hot ring and chemical in specialty LF pPDI(for 苯二异氰 acid ester)预 poly material. LANXESS its in structure - property can 关系PU材 material formulation, process engineering and manufacturing technology upper 60 more year experience, is 客户定 made polymer formulation development. 客户服务 heavy is full has main/primary 经济区 in application development in 心.
