Brief Introduction: PTFE Sulfuric Acid Filter Cloth For Filter Press Factory Direct Sales

Polytetrafluoroethylene is a polymer of tetrafluoroethylene. The English abbreviation is PTFE.
It was discovered in the late 1930s and put into industrial production in the 1940s.

Among fluoroplastics, polytetrafluoroethylene is consumed and has a wide range of uses. It is an important variety in fluoroplastics.

The chemical structure of polytetrafluoroethylene is that all hydrogen atoms in polyethylene are replaced by fluorine atoms.

The PTFE filter screen is one of the performance materials in the world today. It is resistant to strong acids and alkalis. It is an excellent filter in the plastic industry.

It can be called the "Plastic King" because the PTFE filter itself can withstand 98% concentrated sulfuric acid. As well as various mixed acids, it can be used for a long time in various chemical media,

and it is currently the super good material in the international market. Its emergence has solved many problems in my country's chemical, petroleum, pharmaceutical and other fields.

The PTFE filter screen can be customized to different specifications of filter bags, mesh cylinders, etc. according to the different needs of customers.

The PTFE filter screen can be designed with different warp and weft densities according to the strength requirements of the filter material.

The latitude and longitude strength of the base fabric can be greater than 1000N, and the water pressure can reach 50KG!

Performance: PTFE Sulfuric Acid Filter Cloth For Filter Press Factory Direct Sales

It is inert to most chemicals and solvents, and can withstand strong acids and alkalis, water and various organic solvents.

Mechanical properties: Its friction coefficient is extremely small, only 1/5 of polyethylene, which is an important feature of perfluorocarbon surface.

In addition, because the fluorine-carbon chain intermolecular forces are extremely low, PTFE is non-sticky.

Electrical properties: PTFE has low dielectric constant and dielectric loss in a wide frequency range, and has high breakdown voltage, volume resistivity and arc resistance.

Radiation resistance: The radiation resistance of PTFE is poor (104 rad), and it will degrade after being exposed to high-energy radiation, and the electrical and mechanical

properties of the polymer will be significantly reduced.

Sliding property: PTFE filter cloth has a low coefficient of friction and a small coefficient of friction among plastics. It is an ideal oil-free lubricating material.

The friction coefficient changes when the load slides, but the value is only between 0.05-0.15.

Moisture resistance: The surface of the PTFE filter cloth does not stick to water and oil, and it is not easy to stick to the solution during production operations.

If there is a small amount of dirt, it can be removed by simply wiping. Short downtime, saving working hours and improving work efficiency.

Insulation: Not affected by the environment and frequency, the volume resistance can reach 1018 ohm•cm, the dielectric loss is small, and the breakdown voltage is high.

High and low temperature resistance: little effect on temperature, temperature range, applicable temperature -190~260℃.

Surface non-adhesion: No known solid material can adhere to the surface, it is a solid material with low surface tension.

Weather resistance, radiation resistance and low permeability: long-term exposure to the atmosphere, the surface and performance remain unchanged, and there is a longer aging life in plastics.

Non-combustibility: The oxygen limit index is below 90.

Chemical resistance and weather resistance: Except for molten alkali metals, PTFE is hardly corroded by any chemical reagents.

UV resistance: High-frequency wave insulator under high temperature and high humidity, and bleached yarn has better conductivity.
