Through the innovation of reaction medium, optimization of initiation system, design of chain transfer agent and modification of the third monomer, we have realized the precise regulation from the basic resin performance to the high-end application.

The molecular weight and molecular structure regulation technology of the film is the core of optimizing its performance, involving polymerization process, reaction conditions, additive design and other aspects.

It is a key process to significantly enhance the mechanical properties, dimensional stability and optical properties of films by stretching the substrate longitudinally and transversely after the melt extrusion of ETFE resin to orient the molecular chains along the stretching direction.

With excellent weather resistance, chemical stability, optical transparency and mechanical strength, it is widely used in the fields of architectural membrane structure, photovoltaic encapsulation and anti-corrosion coating. Extrusion cast molding technology is one of the mainstream methods of preparing ETFE film, which is characterized by direct molding through melt casting, suitable for large-scale continuous production, and can achieve film thickness uniformity and precise control of surface quality.

Highly efficient, low-cost film production is achieved through a continuous process of melt extrusion - blowing - and multi-stage cooling. The core of the process lies in the precise control of blowing ratio, traction ratio and cooling airflow parameters to solve the challenges of high temperature stability, bubble control and thickness uniformity. In the future, the integration of intelligent control and green manufacturing technology will further promote the application of this process in new energy, semiconductor and other high-end fields.

Modulation of the chemical composition, micro-morphology or energy state of ETFE surfaces through physical, chemical or physicochemical methods can significantly enhance their performance and expand their range of applications.
