Everyone knows that due to the special arrangement of fluorine atoms in polytetrafluoroethylene (PTFE) molecules, PTFE materials have high stability and non-stick properties. Conventional pressure-sensitive adhesives cannot provide large-area, high-strength bonding for PTFE products. Sodium treatment on the surface of PTFE enhances its polarity and surface tension, making the sodium-treated PTFE surfaces capable of bonding with metals, non-metals, and other plastics. Sodium treatment is applied to materials and ranges including: high-temperature adhesive tapes, copper-clad PTFE sheets, mouse friction pads, bridge expansion sliders, and sports arena moving canopy sliders.Sepcifications

Practical Application cases from our customers,After the etched process by us ,the bonding strength is strong and can be completely bonded to stainless steel parts.
The sodium treatment(etched ) of PTFE refers to the method of soaking PTFE in sodium metal solution. This treatment(etched) can form a dense and uniform sodium ion film on the surface of PTFE , which plays a certain role in protection and modification.
1. Improved corrosion resistance;2.Reduce the friction coefficient:;3. Increase mechanical strength;4. Improve conductivity and so on .
In general, sodium treatment(etched) of PTFE can improve its corrosion resistance, mechanical strength and conductivity, improve fluid transport performance and prolong service life.
