PTFE is a non-stick material that is resistant to high temperatures and corrosion and is very smooth, and is widely used in military medical food, etc . However, when it needs to be bonded to the surface of another material, or in order to bond standard PTFE to another surface while combining the advantages of multiple materials, a process called “etching” is required etched ptfe liner.
Typical applications include the lining of chemically processed tubing or other equipment used in corrosive environments. When bonding is required, sodium ammonia etching is usually the most economical answer. This process uses a mixture of sodium and ammonia formulated to create a bondable surface quickly and efficiently.
Sodium/ammonia etching services meet all applicable commercial, military and federal specifications for surface preparation of all fluoroelastomer polymers, including. PTFE, PFA, FEP, ETFE, PCTFE, PVDF, PVF, etched ptfe liner etc.
From microchips to full-size rolls, any shape or complexity of fluoroelastomer polymer, including strips, sheets, tubing, molded shapes and machined parts in any configuration can be etched and bonded. This processing can be done on one or more surfaces, or selectively within tight tolerances.
We can custom etch products etched ptfe liner above ID 0.3mm
