         use masterbatch material to most large difficult is how to it 适当 添 add to material in?

        两 main/primary factors separation is used for production masterbatch resin and its molecular weight, it 们往往 is can 由购买 masterbatch material company can 决定. remove has especially requirements color outer, generally use that for polymer property can generate in bad property raw materials, pellets masterbatch material usually has 30%-50% color agent, its polymer system 如载体 resin, its essence upper is as is color agent bonding 体.

         masterbatch material most resin in add amount generally is 2%-5%

         if positive mixed combined add masterbatch, in most mixed combined material in resin content 占1%-3% or above.

         this 样一 就 make it formed is additives series in content most large types additives, therefore in selection resin 时应该 attention/notes fine 节.

         specific 说, resin and resin is tool has chemical versus property.

        而 most good method is selection and by filling resin is same type type polymer.

         in this in in suitable scope/range.

        例如, can nylon 6 as is resin application in nylon 66 or nylon 46 color upper. this nylon is versus 容, and nylon 6 melting point relatively low, can promote good mixed combined.

        同样, polyoxymethylene (POM) copolymer can as is resin use in polyoxymethylene (POM) homopolymer upper, SAN也 can as is ABS versus 容载体(但 polystyrene (PS) can). in addition for/regarding certain types plastics alloy 而言, can using/adopting alloy in types polymer as is masterbatch material resin.

         in production process in use versus resin as is 载体则 essence upper is 刻意引入污染 material, is 避免造 formed 污染, generally recommendation material processing use and most resin product versus property relatively good 载体. however more 数厂家关心 is how to most low cost meet/satisfy 顾客指定 需 color.

         its in 一 办 method, 就 is use polymer ethylene or ethylene copolymer 如EVA.

         this type of can can is is masterbatch material manufacturing has in-depth understanding 顾客者 or material molding for product use 感受. masterbatch material supply 商 常 through in masterbatch material formulation design add versus property 载体 办 method make difference this competition for 手. is more more supply is force price 战, in 谓 “ general purpose 载体” 基础 upper provide low cost solution/scheme.

         injection molding production plastics 桶 厂家 if in ABS or PC 桶里面发现 polyethylene (PE) pellets, very can can 就会丢弃 it or 者挑拣出不 combined 格 材 material. is lower processing due to add masterbatch material to resin belt/tape 污染, this type of still for most product property can has effect/influence.

         that provide 谓“ salt and 胡椒” mixed combined material supply 商也 一 不 versus material add to it 们自己 product in.

        一 main/primary supply nylon 66 化 combined material supply 商, it in mixed combined material in use nylon 6 as is 载体, large more 数情况 lower also is using/adopting EVA. in nylon 66 positive processing temperature degree lower, EVA in ethylene acid 醋开始发生 thermal degradation, generate material 会引起 screw abrasion loss and product appearance issues, especially is 靠近浇 day and weld lines more add obvious.

         has material polypropylene (PP), is use versus 容 载体 resin color agent to effect/influence. has 一 例子显示, use more active 动铰链 to material container upper cover/cap 子. has color, parts 运行起 没 has issues, appearance performance very positive 常. another other color 铰链, appearance upper its color has from products toward outer slow 释放出 trend, and 经 几次 bending rear 会发生破 bad property fracture. this type of property can upper 差别并不 is is color agent is is masterbatch material in resin and resin versus formed, for masterbatch material resin positive rear this type of process and phenomenon 就会消失.

         false 设载体 resin and resin is versus 容, that 么第二 important property is molecular weight large small, commonly used melt flow rate (MFR) table/sheet 示. usually 说, masterbatch material formulation design is promote more good mixed combined, generally selection types ratio will need by color resin has more high melt flow rate resin as is 载体. 例如, types MFR is 10g/10min polycarbonate (PC), can using/adopting MFR is 20-30g/ 10min masterbatch. high melt masterbatch material in screw in 发生理想 flow more add easy, but also in a large amount of color material in more easy dispersion.

        但 this type of methods 往往也存 in 弊端.

         has 时候MFR and molecular weight between by overlook, molecular weight more effect/influence rear property can. for high MFR resin, in most rear molding separation make product property can has decline can can property large large increase.

         in polyolefin product masterbatch material use in, use high MFI LLDPE resin as is resin, according to different products demand, selection different melt flow index LLDPE grade use 做载体 resin. color masterbatch production can according to products processing process is injection molding also is extrusion, resin flow 情况, product most use force conditions and other design different color masterbatch formulation.
