In today’s society, how to make companies green and environmentally friendly has become an important issue for many traditional manufacturing companies.
The Suzhou manufacturer specializes in the production and sales of environmentally friendly ptfe biaxially stretched film materials. Let’s take a closer look.
There are two main methods for preparing PTFE polytetrafluoroethylene microporous films that have been reported.
One is to add the pore-forming agent NaCl to PTFE, then make the PTFE into a film, and then remove the NaCl by heating and washing with water. The vacancies left by the NaCl form pores. The microporous film made by this method has the smallest pore size. is 0.1μm.
The second is the mechanical stretching method. The microporous film made by the modified method has a special structure of island-like “knots” connected by microfibers. It is currently the main method for preparing PTFE microporous films.
Suzhou New Material Technology Co., Ltd. is a high-tech enterprise specializing in the research, development and production of fluorine material film technology. The ptfe biaxially oriented film we produce uses the mechanical stretching method, which is mainly made of PTFE polytetrafluoroethylene fine After the powder and additives are fully mixed, it enters the extruder. The powder is pushed and extruded into strips of PTFE, which are then rolled into films under a rolling machine.
After heating to remove the additives, it can be stretched longitudinally and transversely. After heat treatment, shaping, cutting and winding, a biaxially stretched microfiltration membrane is obtained.
Our company has a complete set of domestically advanced production lines, and our company can produce products according to user requirements.
The optimized combination of key parameters such as speed ratio, pressure ratio, and operating temperature of PTFE biaxially stretched membrane technology can realize online control of air permeability, thickness and void ratio according to the ratio and pore-forming medium to meet your needs different requirements required.
