         environmental protection type bromine flame retardant

         although currently nitrogen type flame retardant, machine flame retardant and other flame retardant is plastics flame retardant research hot 点, bromine flame retardant its high flame retardant efficiency, wide suitable scope/range, still method by full 取代. is decrease/reduce bromine flame retardant for ring 境 污染, for 人体 毒害以 and for 生态 破 bad, many environmental protection type bromine flame retardant by made development 出, its main/primary is polymerization type bromine flame retardant and reaction type bromine flame retardant .

         polymerization type bromine flame retardant

        1, bromine ring oxygen resin

         bromine ring oxygen resin tool has excellent self-extinguishing property and heat stabilized property, and good light stabilization property, flame retardant property and relatively high melt flow rate, most is Japan 东京芝 company development 推广, main/primary used for electronics 灌封材 material, 随 “二恶英” issues 出现, bromine flame retardant ring issues 逐渐引起人们 heavy 视, bromine ring oxygen resin as is rise grade product 开始推广 application, currently already formed is bromine ether important substitute/replace product, main applications 于PBT, polyolefin, PC/ABS alloy and other polymer/macromolecule material flame retardant. bromine ring oxygen resin and oxidation 二锑复配时, content is 12% left right can make nylon 6, polyester and other material to UL 94 V-0 grade.

        2, bromine polystyrene (PS)

         bromine polystyrene (PS) belongs to add type polymer/macromolecule bromine flame retardant, its appearance is white or color powder 末, solvent water, bromine content large 于65%, hot separation understanding temperature degree large 于310℃, separation structure is long large separation 子, tool has heat stabilized property high, and high poly material versus property good and other advantages, more important is 燃烧时不 generate 二恶英 and other material 质, is types property can excellent environmental protection type bromine flame retardant.

         as is types upper environmental protection type bromine flame retardant, bromine polystyrene (PS) suitable for PBT, PET and other engineering plastics, thermoplastic property plastics and plastics alloy (例如PC/ABS).

         bromine polystyrene (PS) can and oxidation or has machine nitrogen flame retardant 复配, is material provide excellent flame retardant property can.

        3, polypropylene (PP) acid bromine ester

         polypropylene (PP) acid bromine ester is polymerization type bromine flame retardant also excellent product types, bromine content high (70% left right), can based on by flame retardant material demand combined formed different versus for separation quality product, tool has high flame retardant property, excellent hot chemical stability property and electrical properties, 不起霜, 不迁移, processing properties color, can decrease/reduce, made resin 燃烧时 流滴 phenomenon, 且不会释放二恶英 and other material, combined environmental protection requirements.

        4, bromine 化SBS

         bromine styrene – butadiene – styrene copolymer (SBS) is 2012 year Dow company development, 推广 一 types new type large separation bromine flame retardant, USA safety 保护署(EPA) already use bromine 化SBS substitute/replace bromine ring 十二烷, currently already achieve industrial production. bromine 化SBS molecular weight is 10万, its tool has 不出霜, 不迁移, in material and other advantages, structure and polystyrene (PS) has versus property, can widely used in polystyrene (PS) and other polymer/macromolecule material flame retardant.

         reaction type bromine flame retardant

         reaction type bromine flame retardant in polymer/macromolecule polymerization reaction process in, mono 体形式参 add polymerization reaction, formed is polymer separation, formed versus 应 嵌段 or grafting copolymer, in ensure resin has hot property and force property can 变化不 large front lower, make new combined formed material tool has excellent flame retardant property can, meanwhile in use process in generate 析出, phenomenon, for ring effect/influence relatively small.

        1, acrylic bromine ester

         acrylic bromine ester is types reaction type bromine flame retardant, bromine content 约71%, flame retardant efficiency high, ester 基团 存 in make its and polymer versus property relatively good, 不起霜, 不迁移, another, acrylic bromine ester good UV resistant absorption property can 赋予材 material relatively good light stabilization property. acrylic bromine ester also can as is mono 体进一步 combined formed polymerization type bromine flame retardant polypropylene (PP) acid bromine ester.

        2, 二 bromine new alcohol

        二 bromine new alcohol structure is binary alcohol, can substitute/replace more alcohol and binary acid or acid ester and other di can combined material polycondensation reaction formed different saturated and degree and different bromine content resin.

         as is reaction type flame retardant, bromine new alcohol currently main/primary used for polyurethane ester foam flame retardant, due to its structure 特征, made polymer tool has color flame retardant property, for products light stabilization property relatively large effect/influence. meanwhile can as is ultra-high molecular weight polyethylene (PE), foaming polystyrene (PS) add type flame retardant. in addition, it also can as is in combined formed bromine new alcohol acid ester, acid ester and other, molecular weight more high, resistant property can more add good, is non has flame retardant.

        3, 三 bromine new alcohol

        三 bromine new alcohol bromine content high, tool has excellent light heat stabilized property, bromine new alcohol lower product, can 由季戊四 alcohol reaction made, as is reaction type flame retardant suitable for elastomer, coating material and foam 体.
