Self Adhesive PTFE Sheet

PTFE Adhesive Sheet
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 tetra fluoro fluoride surface after sodium
coffee color.

Specification of PTFE Adhesive Backed Sheet
Product name Specification(mm)
Square plate(length) Circular plate(diameter) Thickness
PTFE molded plate Molded plate ≦ 800 ≦800 1-50
Big molded plate 1000̶ 1600 1000-1800 3-30
PTFE skived sheet Skived sheet Width of cloth ≦600 0.5-2
Big skived sheet Width of cloth: 600-1500 0.5-5
Note: Specific size is available as per customer's requirement

PTFE sheet with adhesive is divided into 2 kinds: molded sheet and skiving
sheet. PTFE plastic moulded sheet is made of suspension resin by moulding and
sintering. PTFE skiving sheet is turned with an embryo which is formed by
moulding or hydraulic pressing.

Feature of Self Adhensive 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.
