PTFE flat film is a semi-finished product made from rods and strips extruded from PTFE, calendered into a film, stretched at a temperature below the melting point, and heat-set to obtain a porous product.
The average lifespan of flat membranes on the market is about 5 years in domestic sewage, municipal wastewater, and domestic sewage treatment projects, and the average lifespan in industrial wastewater, pharmaceutical wastewater and other projects is about 3 years. It can be applied to landfill seepage. Filtrate, electroplating wastewater, refractory organic wastewater and other projects.
Polytetrafluoroethylene, referred to as ptfe, also known as tetrafluoroethylene, is a non-polar linear crystalline polymer. Polytetrafluoroethylene flat membrane has many superior properties and is widely used, but the linear expansion coefficient of ptfe is relatively small. It is large and prone to deformation under continuous load; it has poor resilience, low bending and compressive strength, extremely high melt viscosity, and difficulty in forming and secondary processing; and under long-term load, it has large creep and is prone to cooling. Flow phenomenon, this cold flow phenomenon is one of the main reasons currently limiting its wider application.
In recent years, domestic and foreign manufacturers have modified pure PTFE to improve its comprehensive performance to meet different requirements.
PTFE film manufacturer specializes in the production of polytetrafluoroethylene flat film. It has a full set of advanced production equipment and technology, and also has an advanced clean room and an independent composite slitting workshop to ensure the production quality of PTFE film; the products produced The materials are all imported raw materials, with high uniformity, stable performance, good air permeability, and the filtration efficiency can reach 99.999995%! It can basically meet the filtration efficiency grade requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
