crosslinked polyethylene (PE) is types tool has many color features more function material, therefore it in industrial field/area in to application. in this 篇文章, will crosslinked polyethylene (PE) 定义, key features and Common application.

1. what is crosslinked polyethylene (PE)?

crosslinked polyethylene (PE) is XLPE（ or PEX）, is types thermoplastic property polymer. it is 由普通 polyethylene (PE) crosslinked process formed, this will polymer 链连接 in 一起形 formed 三维网络.

crosslinked polyethylene (PE) is through chemical crosslinked methods made formed. will polyethylene (PE) temperature degree, pressure adjustment or crosslinked. process in polymer between formed 共价键, from improve/increase material strong/high degree, flexibility property and resistant ring force cracking.

crosslinked polyethylene (PE) is XLPE or PEX

crosslinked process improve/increase polyethylene (PE) mechanical properties, heat resistant property and chemical resistance can, make its more solid, more heat resistant, more resistant pressure, and easy chemical degradation. it increase material flexibility property and impact resistant property.

polyethylene (PE) crosslinked methods chemical crosslinked, crosslinked and material crosslinked. process can use oxidation material and other catalytic agent in polymer between formed crosslinked reaction.

辐照涉 and will polyethylene (PE) 暴露于 high can lower 如伽马射线 or electronics 束, from 而导致 polymer crosslinked. 另一方面, material crosslinked 依赖于 hot amount or pressure generate polymer crosslinked.

2. XLPE crosslinked polyethylene (PE) key features

crosslinked polyethylene (PE) is types hot solid property polymer, tool has many color property can, make its combined multiple application, specific lower:

2.1 heat resistant property

XLPE key features is its color heat resistant property. it performance excellent heat stabilized property, can high temperature poor 化, therefore it suitable for hot and poor ring in application. crosslinked polyethylene (PE) can in high 达 90°C temperature degree lower 连续运行, can high 达 130°C short temperature degree rise high. （ 源:  Polyethylene Nanocomposites for Power Cable Insulations）

crosslinked polyethylene (PE) can high temperature resistance

2.2 chemical resistance

crosslinked polyethylene (PE) 另一 突出 property can is chemical resistance. XLPE tool has chemical resistance need high cost coating. this type of material can resistant acid, alkali, solvent agent and 油. features let it can suitable for need 接触腐蚀 property material application. in addition, crosslinked polyethylene (PE) pipeline tool has low property, reduce outer factors 污染 风险, ensure 流体输送 system property.

2.3 electrical insulation property

crosslinked polyethylene (PE) tool has excellent insulation property can, therefore, it suitable for manufacturing cable and electrical in. it tool has low dielectric constant and high electrical strong/high degree, can achieve high power/electricity 传输, meanwhile decrease/reduce can amount loss 失.

该 features let it suitable for need a large amount of 接触于腐蚀 property material application. in addition, crosslinked polyethylene (PE) pipeline tool has low property, reduce outer factors 污染 风险, ensure 流体输送 system property.

2.4 water absorption low

crosslinked polyethylene (PE) tool has water absorption low, good anti property, meanwhile in wet ring lower it can anti its electrical and mechanical properties decline. features for/regarding lower cable especially has 益.

2.5. good wear resistance

wear resistance is crosslinked polyethylene (PE) 一 显 advantages. this type of polymer tool has high tensile strength, can 够承受 machine force and outer effect/influence.
crosslinked polyethylene (PE) tool has good wear resistance, resistant property and resistant property. meanwhile, make in poor conditions lower it still maintain good its physical properties, ensure long property can.

例如, PEX pipeline can high water pressure, temperature degree and poor ring conditions 而不会破裂 or 腐蚀. features make PEX formed is pipeline system can selection, ensure most low repair and more cost use.

2.6. flexibility property

XLPE tool has excellent flexibility property, in has 限 空间 inner it can light 松安装 and 布线. and copper or PVC and other rigid property material different, it can light made formed different 形状, let it can 广泛灵 active application. in addition, crosslinked polyethylene (PE) light features make its more easy 于处理 and 运输, 进一步 reinforcement its in construction and pipeline project in force.

2.7 良 good cost 效益

and copper and PVC and other 传统材 material versus ratio, PEX can provide more good high 效. relatively low material cost, add upper easy 于安装 and decrease/reduce requirements, can in project cycle inner more more cost.

in addition, PEX use lifespan and resistant use property decrease/reduce repair or more need, from 而进一步 reduce cost. therefore, construction 商, 承包商 and 房主越 越 more in various application in using/adopting polyethylene (PE) crosslinked, achieve its 经济效益.

3. crosslinked polyethylene (PE) main applications

crosslinked polyethylene (PE) tool has many features can, therefore it by widely used in industry. crosslinked polyethylene (PE) main applications 包括:

3.1 供 water and system

XLPE Common application is in pipeline system in. crosslinked polyethylene (PE) pipeline used for 住宅, and industrial construction pipeline and system. it tool has excellent heat resistant property and chemical resistant product property, ensure water safety property, can property, therefore, it formed is hot water, cold water and 辐射供暖 system selection.

3.2 chemical industrial

crosslinked polyethylene (PE) tool has good chemical resistant product property, therefore in chemical product processing 厂, 炼油厂 and industrial in to application. it used for 输送烈 property chemical product, chemical product 储罐, pipeline, gas pipeline and other.

XLPE广泛 used for manufacturing chemical product 储罐

3.3 automotive industry

XLPE也 widely used in automotive field/area. it tool has heat resistant property, chemical resistant product property and resistant machine force, therefore suitable for manufacturing 线束, tube/pipe and soft tube/pipe. its light amount features has 助于节省燃油并 decrease light weight.

3.4 electrical industry

PEX as is insulation material widely used in power/electricity cable system in, it tool has excellent electrical insulation property, heat stabilized property, resistant wet gas and chemical resistant product property can make it formed is safety has 效传输 power/electricity selection.

PEX widely used in power/electricity cable system in  

3.5 农业 field/area

in field/area in, crosslinked polyethylene (PE) tube/pipe by widely used in system, water tube/pipe and 养殖喷雾 drop temperature equipment system. it can resistant gas, outer 线辐射 and use chemical product.
