PTFE(Etched)
Teflon (Polytetrafluoroethylene)
Product Description：
Teflon PTFE is an amazing non-stick material, but what about when you need to glue it to the suface of another material ? In order to bond standard PTFE to another surface such as stainless steel, a process called "etching" is required. Typical applications would include the lining of chemical process tanks or other equipment used in caustic environments. When bonding is needed, sodium ammonia etching is usually the most economical answer.
