At present, there are many types of waterproof and breathable membranes that we usually call, and ptfe waterproof and breathable membrane is the most widely used material. It is made of porous ptfe with different pore sizes through stretching and other processes. Waterproof and breathable material.
Sensors that need to use thin film protection products include inclination sensors, acceleration sensors, humidity sensors, chemical sensors, position sensors, temperature sensors, magnetoresistive sensors, and angle sensors because their electronic components need to dissipate heat or adapt to changes in the surrounding environment. wait.
PTFE waterproof and breathable membrane products allow air to pass through, prevent solid pollutants, water, and liquids from entering, ensuring that the sensor is not polluted and also ensures the sensitivity of the sensor.
At the same time, the good air permeability of waterproof and breathable membrane products can also promptly balance the changes in pressure difference within the housing caused by temperature changes, thereby extending the service life of the sensor.
PTFE waterproof and breathable membrane is made by special processes such as mixing, extrusion, extrusion, calendering, and biaxial stretching.
Due to the characteristics of ptfe fibrillation, when performing unidirectional stretching (i.e. longitudinal stretching), the ptfe polycrystalline aggregates begin to extend and form some fibrils. The fibrils are parallel to the stretching direction. At the same time, the fibrils The length increases.
The cross-section of ptfe fibrils is wide and thin, its maximum width is about 100nm, and the smallest fibril is ?0.5??1.0nm.
The Suzhou company has introduced a large number of polymer professionals and has a group of professional polymer R&D teams, focusing on the research and development of PTFE polymer technology.
