PTFE surface itself is not adhesive, such as want to bond and other substances must need one side and two sides after Nana chemical treatment, and rubber, metal, and other substances bond, in special use, make up for the non-adhesive performance of polytetrafluoroethylene products.

PTFE nai sodium polytetrafluoroethylene nai sodium surface treatment processing Teflon sodium bonding, PTFE -PTFE nai sodium surface treatment, PTFE tetrafluoroethylene surface is not adhesive, to metal or other substances must be bonded after sodium treatment, after treatment with rubber, metal, plastic, wood, non-metal and other substances bonding. Sodium method - mainly through corrosion liquid and PTFE tetrafluoroborate, strip, film surface chemical reaction, pull off part of the fluorine molecules on the surface, this is left on the surface carbonization layer and some polar groups, so as to get activated tetra fluoro fluoride, tetrafluoroPTFE after sodium increase its polarity and surface tension, ptfe adhesive backed sheet after sodium coffee color.

Feature of Self adhesive backed ptfe sheet
Heat resistance
can work stably from -180℃ to +260℃.
Stickiness
After surface treatment, etched PTFE can be glued to other materials, such as rubber, metal, plastic, etc.
Good mechanical property
No deformation, low friction coefficient.
High Lubrication
Lower friction coefficient in solid material.
