Introduction to three-layer and five-layer composite materials

Do you know what three-layer and five-layer composite materials are? And what is polytetrafluoroethylene? What advantages and performance does it have? What are its uses? The editor will slowly introduce this material to you below.

Polytetrafluoroethylene (PTFE), commonly known as the “King of Plastics”, has a linear macromolecule structure with almost no branches, and both sides of the macromolecule are C-F bonds, which are very stable chemical bonds. Fluorine atoms bind the main chain to The carbon atoms are shielded and protected, and the molecular chain is difficult to destroy. The special molecular structure makes it invulnerable to all poisons. It has good thermal stability, chemical stability, insulation, lubricity, wide applicable temperature range, and chemical stability. Strong, corrosion-resistant, will not hydrolyze, and has good mechanical properties.

At present, there are two methods of compounding three-layer and five-layer composite materials: glue compounding and thermal compounding.

1. Glue lamination is a relatively elementary lamination method, which has low composite strength, is easy to peel off, and has a short service life. Due to the penetration of glue, it has poor air permeability and is not suitable for dust cleaning, which weakens the superior performance of PTFE.

2. Thermal composite advanced composite method completely maintains the superior performance of PTFE membrane, but has strict requirements for thermal composite technology.

It is a three-layer and five-layer composite material manufacturer integrating production, sales and customization.

The company has advanced ptfe film production lines and composite production lines.

The company’s products are widely used in various fields. With strong technical force and strict management system, the company ensures that everything focuses on the interests of users and provides users with high-tech, high-quality, high-performance, and high-level products.
