YaolongNonwoven's PTFE0027 polytetrafluoroethylene (PTFE) laminated nonwoven is type of performance material which use the polyester spunbond nonwoven as the base material and laminate with PTFE microporous membrane. PTFE membrane to be laminated by a special process on a variety of nonwoven fabrics and substrates, become a new type of filter material.
Features of smooth surface, chemical resistance, breathable impervious, flame retardant, high temperature resistance, strong acid and alkali resistance, non-toxic and other characteristics. PTFE0027 enhances the filtration efficiency. The membrane has small pore size (0.05～0.45μm), uniform distribution and large porosity. While keeping air in circulation, all dust particles, including bacteria, can be filtered to purify and ventilate. It is widely used in pharmaceutical, biochemical, microelectronics and laboratory supplies and other fields.
What would be the speciality of PTFE0027 performance nonwoven?
You should know what is the PTFE first. It is known by such trademarks as Teflon, Fluon, Hostaflon, and Polyflon, PTFE is distinguished by its slippery surface, high melting point, and resistance to attack by almost all chemicals. These properties have made it familiar to consumers as the coating on nonstick cookware; it is also fabricated into industrial products, including filtration .
Charicteristics of PTFE0027 polytetrafluoroethylene (PTFE) lamination
1. Excellent temperature resistance
High temperature resistance: High melting point of PTFE0027 is around 327 °C (620 °F).
Low temperature resistance: Good mechanical toughness, even if the temperature drops to minus 196 ℃, the elongation rate of 5% can be maintained.
Often use temperature:190~250℃ to allow sudden cold, hot or cold alternating operation.
2. Chemical stability and corrosion resistance which is the world's most corrosion-resistant materials one of the best. Resistance to attack by almost all chemicals.
The oxygen-limited index is below 90.
4. Weather resistant/Oxidation resistance
5. High lubrication
7. No toxicity
8. Electrical insulation
