PVDF coated aluminium and PE coated aluminium are both common coated aluminium materials, they have certain differences in nature, application and service life. 

The characteristics and differences of these two types coated aluminium materials will be introduced in detail below.


1. PVDF Coated


PVDF coated aluminum is a kind of coloured aluminum material based on polyvinylidene difluoride (PVDF), which has the following characteristics:


Strong corrosion resistance: PVDF coated aluminum has good corrosion resistance and can resist the erosion of acid and alkali and other chemical substances, which is suitable for making chemical equipments, pipelines, containers and so on.


High mechanical strength: PVDF coated aluminum has high mechanical strength and hardness, able to withstand greater pressure and impact, suitable for making mechanical parts, tools and so on.


Good performance of high temperature resistance: PVDF coated aluminum has good performance of high temperature resistance, able to maintain stability in high temperature environment, suitable for making kitchen utensils, ovens, etc.. It is suitable for the occasions that need to withstand greater pressure, impact and high temperature.


2. PE Coated


PE coated aluminum is a kind of coloured aluminum material based on polyethylene (PE), which has the following characteristics:


Light weight: PE coated aluminum has a lower density, which makes the product lighter and suitable for making lightweight and portable products.


Lower price: Compared with PVDF coated aluminium, PE coated aluminum has a lower price, which is suitable for occasions where costs need to be controlled.


Compared with PVDF coated aluminum, PE coated aluminum has the characteristics of light weight, good flexibility and lower price, which is suitable for making light weight and good flexibility products. At the same time, PE coloured aluminium also has better corrosion resistance and high temperature resistance, but compared with PVDF coloured aluminium, it is slightly inferior.


To sum up, PVDF coated aluminum and PE coated aluminum have their own characteristics, and you can choose the suitable coated aluminum material according to the different needs of application scenarios. If you need to withstand greater pressure, impact and high temperature, you can choose PVDF coated aluminium; if you need to make lightweight, flexible products, you can choose PE coated aluminium.


At the same time, according to the requirements of budget and service life, you can also choose the appropriate material.
