2 Extrusion System
2.1 six layer introduction
6 layers | Material | thickness rate | adjustable | brief introduction of each layer | |
Layer | base layer or inner layer | New material HMWHDPE | 35%~40% | it's the main body of the fuel tank whose function is to assure the strength, stiffness and stablility, and also as functional layer in a degree. | |
Layer | recycling layer | recyling PE or mixture of the recyling PE and new HMWHDPE | 35%~45% | as high as 50% | To save cost by collecting some little crash and NG during the production. Meanwhile, it's no matter how many times it recyles. |
Layer | outer layer or decoration layer | New material HDPE and any assistants | 12%~15% | as high as 20% | The outer layer also has a certain strength and stiffness. Besides, color master batch cal also be input to have different colors of the fuel tanks. Or,Anti ultraviolet agent and other assistants can also be applied to help with environmental adaption of the fuel tanks. |
Layer | adhesive layer or connecting layer | TIE | 2%~3% | can be adjusted to 1% | To better connect the functional layer with the base layer, recyling layers. It's the key of multi-layer co-extrusion. |
Layer | functional layer or EVOH Barrier layer | EVOH | 3.5%~4.5% | can be adjusted to 1% | functional layer is the key layer of high barrier. It stops the useful material of the fuels going out of the tank, and also stops the air or moisture coming inside the tank. |
