New waterproof and breathable material ptfe ultra-wide membrane
For many years, fabrics, clothing, waterproofing and breathability have been a contradiction.
With the development of the economy, the advancement of science and technology, and people’s continuous exploration and research, many new types of waterproof and moisture-permeable materials have been discovered, including PTFE ultra-wide membrane.
Polytetrafluoroethylene (PTFE) is an engineering plastic that is widely used. It has excellent properties such as excellent medium resistance, low friction coefficient, and wide operating temperature range. It plays an important role in sealing and lubrication and other fields.
Due to the high melting temperature and melt viscosity of PTFE, which makes it difficult to process, a common processing method is to process it through cold pressing sintering similar to metal powder metallurgy.
In the actual production process, sintering is an important part of PTFE molding processing. Process conditions such as sintering temperature, holding time, heating/cooling rate, etc. directly affect the degree of sintering of the blank, which in turn affects the final performance of the product.
The ptfe ultra-wide membrane has undergone high-temperature heat setting treatment. The microporous structure is very stable and can effectively intercept dust particles.
The pore size of the material is small and the distribution is concentrated. Surface filtration is achieved to achieve a dust removal efficiency of 99.9%~99.999%. For some extremely small particles with a diameter of 0.1um-0.3um, it can better prevent fine dust from entering the filter material.
Can operate at a continuous operating temperature of 240°C and an instantaneous temperature of 260°C.
It is a ptfe ultra-wide film manufacturer that specializes in R&D, production and sales.
The materials of the products produced by our company are all imported raw materials, with high uniformity, stable performance and good breathability.
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.
