Shanghai Daoqin Plastics Co., Ltd.

         dispersant is types in separation inner meanwhile tool has hydrophilic property and hydrophilic water property types versus property interface active property agent. can dispersion that difficult solvent understanding liquid 体 无 machine, has machine material solid pellets, meanwhile can anti solid pellets drop and poly, formed 安定悬浮 liquid 需 药 agent.

        1. acid type, aliphatic amine type and ester type

         hard amine and high grade alcohol use, can improvement lubricated property and heat stabilized property, use amount (quality separation 数, lower 同)0.3%-0.8%, also can as polyolefin slip agent;己烯基 di hard amine, 也称乙撑基 di hard amine, is types high melting point lubricant, use amount is 0.5%～2%;

         hard acid mono ester, hard acid ester;油 acid use amount 0.2%～0.5%;烃 type wax solid 体, melting point is 57～70℃, solvent water, solvent has machine solvent agent, resin in dispersion property, versus property, heat stabilized property 均差, use amount generally in 0.5% below/following

        2. wax type

        尽 tube/pipe wax belongs to outer lubricant, is non property 直链烃, can lubricating wet metal surface, is can retardant polyvinyl chloride (PVC) and other resin viscous metal 壁, has and hard acid, hard acid and other use 时, can 发挥协同效应.

         liquid wax: solid 点-15--35℃, in extrusion and injection molding processing 时, and resin versus property relatively 差, add amount generally is 0.3%-0.5%, more 时, make processing properties bad.

         micro wax: 由石油炼 made process in to, its versus for separation quality relatively large, has many 异构体, melting point 65-90℃, lubricated property and heat stabilized property good, dispersion property relatively 差, use amount generally is 0.1%-0.2%, most good and hard acid ester, high grade acid use.

        3. metal type

         high grade acid metal salt type, is metal 皂, hard acid suitable for multiple plastics, use amount is 0.5% left right; hard acid zinc polyolefin, ABS and other, use amount is 0.3%; hard acid 钙适于 general purpose plastics, outer lubricated use, use amount 0.2%-1.5%; other hard acid hard acid 镉, hard acid 镁, hard acid copper.

        4. low separation wax type

         low separation wax is various polyethylene (PE) (homopolymer or copolymer), polypropylene (PP), polystyrene (PS) or other polymer/macromolecule modified material is raw materials, understanding, oxidation formed series property can oligomer.

         its main/primary product has: homopolymer, oxidation homopolymer, ethylene - acrylic copolymer, ethylene-vinyl acetate copolymer (EVA), low separation ionomer and other large type. its in polyethylene wax, polyethylene wax Scientific Names is poly ethylene glycol, 英文名PEG(Poly Ethylene Glycol) most is commonly used.
