hits: 'time: 2021-01-15

PTFE fiber needle felt is a kind of chemical properties stability fiber, its features are as follows:

--- the continuous working temperature is 250 degrees, the instantaneous temperature is 280 degrees;

--- totally not afraid of pH and oxidation, hardly inflammable;

--- one and only not aging fiber;

--- meet the worst condition, has the extremely long service life, usually life in three years.

100% PTFE needled felt fiber material is mainly used in chemical industry, waste incineration, high temperature resistant liquid filtration, keeps good chemical stability in the complex condition
