polyethylene wax （Polyethylene wax）, 简称PE wax . made 备 polyolefin wax and polyolefin plastics reaction mechanism and its steps essence upper is same, 都源自 ethylene polymerization.

区 separation polyolefin plastics and wax most important parameters is 平均摩尔 quality . PE wax more 达几百 ethylene mono formed, most large is 10,000道尔顿. PE plastics cover/cap high wax scope/range, 几乎没 has upper 限: ultra-high molecular weight polyethylene (PE) （UHMWPE）, in can 达数百万 mono 元.

usually, polyethylene wax less has types production methods:

1.  ethylene mono 体 寡 poly or polymerization:

⚬  high pressure free radical polymerization

⚬ 基于齐格勒- nano catalytic agent low pressure ethylene polymerization

⚬ 基于 metallocene catalytic agent low pressure ethylene polymerization

2.  polymer/macromolecule amount polyethylene (PE) plastics thermal degradation;

3.  from polyethylene (PE) plastics in separation relatively low molecular weight separation;

4.  different 源 “ waste wax ”, recycling and wax mixed combined.

ethylene mono 体 寡 poly or polymerization in types different process

1. high pressure polymerization High-Pressure Polymerization

low density polyethylene (PE) （LDPE） wax is through high pressure free radical polymerization （FRP） production. 自由基 reaction is and 自由基 任何 chemical 反, is machine chemical in reaction mechanism 之一. FRP main/primary steps 包括: separation understanding, reaction 开始, reaction growth, reaction 终止. FRP reaction need high pressure.

几十 year, has 两 著名 LD PE wax production 商:

⚬ BASF（ Germany, 路德维希港） provide Luwax® polymer, this combined formed wax through high pressure ethylene （共） polymerization production.

⚬   Honeywell （ USA new 泽西州莫里斯敦） production and sales its A-C® series LD PE wax （A-C代 table/sheet has combined chemical company ）

this company not only provide low density polyethylene wax homopolymer, also provide copolymer, oxidation wax and grafting wax. remove this 两家历 history production 商, PE wax also can from 亚洲国家如印 degree, China, Korea and other company obtain.

2.  low pressure 齐格勒- nano polymerization Low-Pressure Polymerization

该 polymerization reaction 基于Ziegler–Natta（齐格勒- nano 塔） catalytic. from upper 讲, it is 指基于 titanium combined material more versus catalytic agent and aluminum catalytic agent combined use. will this type of “ catalytic agent system ” add to high degree pure 化 无 oxygen type solvent agent in ——例如柴油 or relatively low liquid 体, positive 己烷——形 formed liquid, rear toward its in gas 态烯烃.

need production 齐格勒- nano polyolefin wax, need use 齐格勒 catalytic agent, this type of catalytic agent can formed 平均链 long relatively low long distribution narrow polymer, and in wax combined formed conditions lower tool has active property.

齐格勒- nano method production polyethylene wax main/primary to property, 无支链 separation 子, from generate high density product, 即HDPE. through toward reaction mixed combined material in add copolymer, most good is propylene, density can in 一定程 degree upper reduce, from 而改变 its application property can.

3.  low pressure metallocene polymerization Low-Pressure Metallocene Polymerization

“ metallocene wax ”简而言之 is certain polyolefin wax, through in metallocene catalytic agent and 特殊 基于 aluminum 烷基共 catalytic agent （烷基 aluminum oxygen 烷） 帮助 lower polymerization ethylene or propylene and other short 链烯烃 combined formed formed.

metallocene （ outer 文名: metallocene） is 由 渡 metal and ring 戊二烯基配体 through η键形 formed has machine metal 配位化 combined material, type structure is ring 戊二烯基以夹心形式键 alloy 原子.

2010 year, Clariant（ Clariant ） company in 原Hoechst厂区建立 year 产约20000吨 wax factory, factory using/adopting metallocene process production.

PE wax market and main/primary and 者



截至2022 year , 预估 full 球PE wax year 总 production capacity （包括 has production product types ）约 is 50 10,000 tons, year 营业额 ultra- 10 100 million USD.

PE wax market main/primary and 者包括:

BASF（ BASF ）

Clariant（ Clariant ）

Idemitsu（ Idemitsu 兴产）

Innospec

Honeywell International Inc.（ Honeywell company ）

SCG Chemicals Co., Ltd.

Westlake Chemical Corporation

Baker Hughes（贝克休斯）

Mitsui Chemicals（ Mitsubishi chemical ）

Hase Petroleum Wax Co. （石 wax, polyethylene wax and other ）

Marcus Oil & Chemicals Private Ltd. （完 full made polyethylene wax ）

Trecora Chemical （ specialty carbon hydrogen combined material, specialty wax, lubricated additives ）

OPI INC. （ high density, high melting point oxidized polyethylene wax main/primary manufacturing 商）

remove outer, has company not only provide multiple different polymer, also provide related technology. 例如, LyondellBasell（ LyondellBasell industrial company, Netherlands 鹿特丹） use different technology production different types type polyethylene (PE) product —— high density polyethylene (PE) （HDPE）, low density polyethylene (PE) （LDPE） and property low density polyethylene (PE) （LLDPE）. ExxonMobil（ ExxonMobil, USA 克萨斯州欧文市） is has main/primary type type polyethylene (PE) （HDPE, LDPE or LLDPE） most large production 商之一, has has related production technology.
