Polytetrafluoroethylene composite material is a new type of material formed by compounding a layer of polytetrafluoroethylene (PTFE) film on the surface of ordinary filter media. Currently, this material has a wide range of applications.

At present, my country’s PTFE production capacity is about 114,000 tons, accounting for more than 40% of the world. Among them, Dongyue Group has 45,000 tons, accounting for 39% of the total domestic production capacity. From 2013 to 2016, PTFE production increased steadily, from 60,000 tons rose to 80,000 tons.

The operating rate also increased from 55.7% to 70.7% during the same period. In the first half of 2017, PTFE output stabilized at around 40,000 tons.

The filtration principle of polytetrafluoroethylene composite material is completely different from the depth filtration of ordinary uncoated filter materials. Its filtration principle belongs to surface filtration.

The filter medium is a PTFE microporous membrane with high efficiency interception capability. This PTFE microporous membrane is pressed onto a special base material, and the selection of the base material should be consistent with the mechanical, temperature, and chemical requirements of the system. consistent.

The film is a chemically inert material.

The working temperature is 260 degrees Celsius, and the highest instantaneous temperature is 285 degrees Celsius.

The polytetrafluoroethylene composite material produced has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can achieve high dust removal efficiency. For some extremely small particles with a diameter of 0.1um-0.3um For particles, the filtration level can reach H13-U16.

In addition, biaxially oriented film can undoubtedly achieve ultra-low emissions in intercepting various types of dust generated during the production process of the company, and it fully complies with current environmental protection standards.

The company can provide samples and arrange sales staff to provide door-to-door service if there are other requirements.

You are welcome to come to the company for inspection or enter the store to consult us at any time.
