As the concept of green environmental protection slowly takes root in people’s hearts, the environmentally friendly material ptfe high temperature filter membrane is also constantly in demand and valued.
The environmentally friendly material ptfe high temperature filter membrane is made of polytetrafluoroethylene (PTFE) material through special processes such as mixing, extrusion, extrusion, calendering, and biaxial stretching.
In production, the stretching temperature of PTFE microporous membrane is related to the stretching rate and speed, and also depends on the strength and size of the product.
High temperature makes the film soft and easy to stretch, has good dimensional stability and is not easy to shrink.
However, if the temperature is too high, the strength of the product will be reduced, which may also lead to breakage.
The greater the stretching ratio, the higher the required temperature, because a lower stretching temperature requires a larger pulling force. When the pulling force exceeds the strength that the drawn product can withstand, it will break; conversely, the stretching The rate is small and the temperature can be lower.
Differences in temperature also directly affect the performance indicators of its products. Therefore, it is necessary to find the optimal range suitable for specific processes and equipment during production.
The strength, pore size and porosity of PTFE microporous membrane are important indicators that determine the quality of PTFE high temperature filtration membrane.
Suzhou New Material Technology Co., Ltd. is a manufacturer of polytetrafluoroethylene microporous membranes that specializes in R&D, production and sales.
The ptfe materials we produce are all imported raw materials, with high uniformity, stable performance and good air permeability.
It also has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
Also according to user’s requirements.
The optimized combination of key technical parameters such as speed ratio, pressure ratio, operating temperature, etc. can realize online control of air permeability, thickness and void ratio according to the ratio and pore-forming medium to meet the different requirements you need. .
