e-ptfe waterproof breathable membrane, also known as expanded polytetraffluoroethylene microporousmembrane, is a polymer waterproof material.There are two common welding methods for e-ptfe waterproof and breathable membrane, mainly toweld the breathable membrane on the plastic to achieve a sealing effect, one is hot melt welding, andthe other is ultrasonic welding. SDA Shangda’s technicians believe that hot melt welding is better thanultrasonic welding.
hot-pressing waterproof and breathable membrane welding machine uses hot melt technology forwelding, and welds the diaphragm with the main body of the plastic breathable valve. The main principleis to use the difference between the main body of the plastic breathable valve and the e-ptfe waterproofand breathable membrane to melit the main body of the plastic breathable valve and weld thediaphragm. SDA Shangda waterproof breathable membrane of a variety of support materials, differentsupport materials, melting point is also different.

plastic ventilation valve body and eptfe waterproof breathable membrane using hot melt weldingalthough slow, but the effect is good, quality pass. This functional waterproof material will have to usehot melt welding!
e-ptfe waterproof membrane has been applied in various fields, such as consumer electronics, 5Gcommunication equipment, smart wearable devices, solar photovoltaic, electric vehicle parts, etc.
