Polytetrafluoroethylene(PTFE) is commonly named asTEFLON, generally known asnon-sticking liningoreasy-to-clean material. This material has the characteristics of acid resistance, alkali resistance, resistance to various organic solvents, almost insoluble in all solvents, high temperature resistance and extremely low friction coefficient. Its advantages are significant and it is also a very common material in the case of relatively high requirements, but the price is relatively expensive. PTFE film includes PTFE tape for water, PTFE tape for gas, etc.



1. There Are Mainly Two Kinds of Teflon Adhesive Tape

(1) Pure Teflon Adhesive Tape

Pure teflon adhesive tape is made of pure teflon turning film, which is treated on one side with adhesive. It is characterized by good electronic insulation, strong chemical corrosion resistance, anti adhesion and good temperature resistance. Teflon film includes 100% PTFE thread seal tape, 100% plumbing tape, etc.

(2) Teflon Glass Fiber Adhesive Tape

Teflon glass fiber adhesive tape is mainly made of teflon and glass fiber base cloth, which is treated on one side and coated with adhesive. It is characterized by better strength than pure teflon tape, anti adhesion, temperature resistance and corrosion resistance.



2. Advantages of Teflon Tape

(1) High Temperature and Low Temperature Resistance

It has good mechanical toughness. Even when the temperature drops to -196℃, the elongation can be maintained at 5%. It is applied at low temperature between -196 and 300 degrees Celsius. It has weatherability and anti-aging. If it is placed at 250℃ for 200 days, not only the strength will not be reduced, but also the weight will not be reduced in practical application. After 120 hours at 350℃, the weight is only reduced by about 0.6%. The original softness can also be maintained at -180℃.


It has good heat resistance (continuous use temperature above 260℃) Especially the heat-resistant PTFE tape can be applied safely even if it is overheated.


(2) Non-stick Performance

It has the minimum surface tension, smooth surface, and does not adhere to any substance in solid materials. All kinds of oil stains, stains or other attachments on the surface are easy to be cleaned. Paste, resin, coating and almost all adhesive substances can be simply removed.


(3) Chemical Resistance

It shows inertia to most chemicals and solvents. It can resist the corrosion of strong acid, strong alkali, aqua regia and various organic solvents.

(4) Drug Resistance and Non Toxicity

It is resistant to almost all medicaments.


(5) It Has High Insulation Performance

The dielectric constant is 2.6 and the tangent is below 0.0025. It is anti ultraviolet and anti-static.


(6) Fire Retardant


(7) Easy to Use and Long Service Life


(8) Weather Resistance

It has the best aging life in plastics.


(9) High Lubrication

It has the lowest friction coefficient among solid materials.


PTFE sealing tape is widely applied in packaging, thermoplastic, composite, heat sealing, electronic and electrical industries. The fabric reinforced PTFE teflon tape has the characteristics of high strength. It can be applied in sizing machine roller, thermoplastic demoulding and other industries. It can be applied repeatedly and easily replaced. PTFE tape includes expanded PTFE film, PTFE unsintered tape, PTFE cable tape, etc.
