ptfe sheet can be devide into teflon skived sheet, teflon mold sheet and ptfe film.

the size of ptfe mold sheet:

length*width(mm)

150*150,250*250,300*300,450*450,600*600,800*800,1000*1000,1200*1200,1000*2000 and so on.

the thickness is from 5mm-100mm.

the size of ptfe skived sheet:

the thickness is from 0.2mm-7mm,

the length had no limited.

the width is about 850mm,1000,1200,1500,1800,2000 and so on.

main properties:

applications:

lining bearing pads,seals,and electrical insulation.

1)      Features of skived ptfe films:i.anti-corrosion in all kinds of chemicals including nitric acid & aqua fortis ;ii.good dielectric in mediums;iii.non-aging;iv.can be used in wide strength range etc.

2)      Use of skived PTFE films:i.seal liner and lubricant material in kinds of medium,especially corrosive situation.ii.dielectric material in kinds of frequency;dium material of capacities;iv.insulation materials in electrics systems,etc

3)      Specifications of skived ptfe films

Thickness 0.03-0.1*width 30-100-length 10+m

Thickness 0.1-0.5*width 100-2500+length 5+m

in fluoroplastics,ptfe got the most consumption and was used widely.its an important variety of fluoroplastics.ptfe all of the hydrogen replaced by fluoride.ptfe exhibit astonishing chemical resistance,this self-lubricating materials for the manufactures of corrosion-resistant gaskets&seals.one of the most chemically resistant materials available,ptfe can approaching 500f(280 degree).it also has a high oxygen level.

advantage:

1.superior endurance in corrosion.

2.superior endurance in seasonal change.

3.non-flammable,limited oxygen index is under 90.

4.low friction coefficient.

5.non-viscous

6.superior endurance in high&low temperature,can be used -190degree-260degree

7.high electricity insulation

8.high electrictiy resistance coefficient

9.self-lubricating

10.atmospheric aging resistance

11.radiation-resistance properties and low permeability
