Self Adhesive PTFE 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 Adhesive Backed PTFE 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.
