Shanghai Daoqin Plastics Co., Ltd.

ABS belongs to easy material, according to UL 94 standards belongs to HB grade 别. ABS 火时燃烧 speed degree fast, 并放出 a large amount of gas and 黑烟, 不利于实际 application. 随 科技进步 and active quality improve/increase, safety 意识越 越 strong/high, inner outer for automotive, construction, use electrical appliances, office supplies and other use plastics material 提出 严格 anti flame retardant requirements, made versus technology standards and specification, therefore flame retardant ABS research tool has versus important 意义.

    flame retardant ABS is in ABS upper add flame retardant, formed is to flame retardant 效果 ABS plastics. ABS resin mechanism separation complex,   due to use raw materials types type, ratio/proportion, process conditions, production methods more 样化, ABS resin 实际组 formed 千差万别, 变动极 large, its property can has 差异. generally butadiene formed separation increase, resin transparent property reduce, can property increase.

     how to separation 辨ABS material is is flame retardant?

    comparison simple method is use 夹子 ABS products 夹住, rear use machine and other 燃烧时 打火 machine 离开, if self-extinguishing, generally is flame retardant type, flame retardant type grade separation also is has good several 档次, ratio 如 UL 90V0 grade, V1 grade, V2 grade, B1 grade, B2 grade, H grade and other .....

        ABS flame retardant material material material property can

    comprehensive property can relatively good, impact strong/high degree relatively high, chemical stability property, electrical property can good .

    and 372 has machine 玻璃 熔接 property good, made formed di color parts, can surface 镀铬, 喷漆处理.

    has high impact resistance, high heat resistant, flame retardant, reinforcement, transparent and other grade 别.

    flow property ratio HIPS差一点, ratio PMMA, PC and other good, flexibility property good.

    made as generally machine parts, decrease abrasion wear resistant parts, parts and electrical parts.

    flame retardant ABS in 公共场 消 anti safety in application

    flame retardant ABS resin product types more 样, features same, widely used in various electronics electrical appliances product. in 公共场 设施 in, combined utilizing flame retardant ABS resin, can is 公共场 消 anti safety provide has safety 保障. according to different equipment specific use requirements, for/regarding material features requirements 也不尽 same.

       1, 视听 equipment

liquid electrical 视

        due to development water improve/increase, 出于宣传 need, is 方便顾客, in very more 公共场 都配备 electrical 视, and other equipment. type product is liquid electrical 视. according to different requirements, liquid electrical outer housing/shell selection different flame retardant ABS. ratio export Europe high gloss spray coating product usually selection high gloss flame retardant PC/ABS alloy, can meet/satisfy WEEE requirements, can meet/satisfy Europe TCO’03 environmental protection requirements. 而免喷 普通 product, large dimensions electrical usually selection bromine ring oxygen resin flame retardant ABS resin, meet/satisfy product processing requirements. small dimensions product usually selection bromine di 酚A environmental protection flame retardant ABS resin, 以节约 cost. export USA, or its it has RoHS 指令 related requirements liquid electrical 视支架, electrical appliances box/case and other internal made parts, usually can using/adopting bromine ether flame retardant ABS resin.

      2, electrical device 材

排插

        electrical device 材如排插, 墙壁开关, electrical table/sheet, electrical and other product, usually has frequency 繁 开闭路工 as, very easy generate electrical 火花, if housing/shell selection material flame retardant property can 不够甚至不 flame retardant, is 引起火灾 important 源头. 我国早 already for related product related standards and regulations, is due to tube/pipe hydrophobic 漏, various poor product still 然充斥 market, is 公共消 anti safety heavy large 隐患. electrical device material selection is non important, types product use combined meanwhile, 也应该 according to specific requirements selection combined 适 材 material. 以排插 is 例, 10A use ABS/PVC alloy already 经足够, is electrical relatively low, hot amount large, usually 不会导致 housing/shell material deformation, generate safety 隐患. electrical 流30A 排插, must 考虑极限 conditions lower product temperature rise, selection high heat resistant flame retardant ABS甚至 is flame retardant PC/ABS alloy material outer housing/shell, 避免排插 use process in, due to temperature rise high, product deformation, generate heavy safety 事故.

      3, anti safety equipment

full 自动应急灯

       消 anti safety equipment 例如应急灯, 烟雾探测 device, device and other product, requirements must tool has very high can property, in 紧急状态 lower still can positive 常运转一定 time, is 挽救人们生命财产 safety provide time and 指引. usually requirements material tool has good flame retardant property, meanwhile in relatively high temperature degree lower can deformation, amount long poor conditions lower equipment lifespan.

       4, electrical 源转换 plant/unit

electrical 源转换 plant/unit

        electrical 源转换 plant/unit usually 包括UPS electrical 源, electrical appliances, and various electrical appliances product electrical control box/case. this equipment main/primary function is through plant/unit formed 交直流 electrical 源 转换 or through rate stability electrical pressure, provide electrical appliances product need 交直流 electrical 源. in as process in 也常常伴随 frequency 繁 开闭路动 as, easy generate electrical 火花. meanwhile, due to tool has 一定 功 rate, usually 也会伴随一定 temperature rise. due to this category of product structure comparison complex, dimensions relatively large, more is cosmetic parts, need according to product specific requirements selection different flame retardant ABS. 空调, and other home appliances electrical box/case generally selection TBBA flame retardant ABS resin. electrical appliances outer housing/shell material according to use requirements different selection TBBA flame retardant ABS resin, bromine ring oxygen flame retardant ABS resin or high heat resistant PC/ABS resin.

        5, OA equipment

OA equipment

         company, enterprise office and other 公共场 往往人员密集, office equipment （OA） more, 经济价 value high, power/electricity complex, especially need attention/notes anti safety. type OA equipment 包括显示 device, printing machine, machine, machine and other electronics electrical appliances product. generally 而言, this electrical appliances product for/regarding material safety property requirements relatively high, machine outer housing/shell is dimensions relatively large, appearance requirements high, relatively more using/adopting flame retardant PC/ABS alloy, device outer housing/shell more using/adopting TBBA flame retardant ABS or BEO flame retardant ABS, has product is meet/satisfy TCO’03 environmental protection requirements, use flame retardant PC/ABS alloy. its it 如碎纸 machine, printing machine and other small type OA equipment, according to different product structure and weather resistant requirements, selection different flame retardant ABS resin.
