PTFE Teflon Tape Making Process

• The raw PTFE powder is sifted through wire mesh sieve. 
• The powder is mixed with a wet lubricant in a blender by mixer machine.
• The lubricated powder is placed in the mould in a hydraulic press and pressed to form a billet by pressing machine.
• The billets are then hydraulically extruded to form the ribbon which is continuously wound. 
• The ribbon is then calendared to flatten into thin sheet by calandar machine.
• The sheet is wound on roller. 
• The rolls are then dried in oven to remove the lubricant by deoiling machine 
• The sheet is stretched and slitted to desired width by slitting machine.
• The tape is finally rewound into small spools by rewinding machine.

The above steps are PTFE Teflon tape machine making process .

Yellow Gas Thread-Seal PTFE Teflon Tape

               Yellow Gas Thread-Seal PTFE Teflon Tape

A color-coded, full density, PTFE thread-sealing tape designed for the gas industry.

Description
Yellow Gas Thread-Seal Tape is a thick, full-density (maximum) density PTFE thread-sealing tape designed spe- cifically for gas lines. Unlike most thread-sealing tapes on the market, Yellow Gas Thread-Seal Tape has not been stretched during the manufacturing process. Stretching low- ers the apparent density of the tape by increasing its porosity. As stretched tape is more porous, more is required to obtain an effective seal. A stretched tape also is flimsy and difficult to work with, and is more likely to shred and string. The amount of tape wasted is high. With ResTape full density tape, these problems are avoided. Yellow Gas Thread-Seal Tape is approved by relevant authorities and is used by the gas industry world-wide. It is color-coded yellow so fitters and inspectors can easily recognize it as an approved tape.

Applications

Yellow Gas Thread-Seal Tape is manufactured from PTFE resin, a polymer consisting of recurring tetrafluoroethyl- ene monomers whose formula is (CF2 - CF2)n by higher quality PTFE Teflon tape machine. One of the most inert substances known it is compatible with a very wide range of materials. ResTape Yellow Gas Thread-Seal Tape can be used on pipe made from galvanized steel, iron, brass, copper, alumi- num, stainless steel, polyethylene, polypropylene, PVC, CPVC, ABS or fiberglass. It can be used on pipes carrying the following materials:

· Acids, concentrated (see precautions) or dilute
· Air, compressed
precautions) or dilute · Chlorinated solvents

· Heating oils

How to use thread seal tape?

How to use thread seal tape?

Thread seal tape is a very thin white tape used to wrap the threaded ends of metal and plastic pipes to lubricate the threads and prevent leaks where pipes join. The thin tape fills the minute gap between the male and female pipe threads stopping water leaks. 

The alternative is to use pipe dope, a paste type material which also seals and lubricates, allowing for a tighter joint. There is also a another variety of thread seal tape that is yellow. The yellow tape is heavier and is for use on gas line connections. Never use regular, white, Teflon tape on gas connections.

Now PTFE thread seal tape machine manufacturer tell you how to use thread seal tape as following :

•  Clean the pipe threads with a rag before applying the Teflon tape.

• Start wrapping the male threads at very end of the pipe, but do not let the tape lap over the end. If the tape laps over the end of the pipe it can reduce water pressure and even cause clogs from bits of the tape that get pulled into the water line.

• Start with a couple loops around at the end, then wrap all the threads, overlapping half the width of the tape on each wind.

• Wrap in the direction of the threads starting from the end and proceeding toward the length of the pipe. Wrapping the wrong way may result in the tape coming unwound as the fittings are tightened.

• As you wrap, keep tension on the tape so that it is pulled into the threads.

• If you loosen or disconnect a fitting, remove the old tape and re-wrap it with a fresh piece.

The above is about some of the using process of PTFE thread seal tape , we produce AMSTAR brand PTFE thread seal tape with good quality products, We make customer satisfaction as our goal and our products worth you choosing . we are look forward to your visiting and calling.

What are the plasticity temperature requirements of the PTFE tape?

The PTFE thread seal tape is a novel and ideal sealing material and it is made by PTFE Tape machine. The PTFE tape is made of 100% pure materials and advanced technology, with high quality and complete specifications, and it can meet the requirements of different industries and customers. Products with excellent insulation, strong chemical stability and good sealing performance, because of its non-toxic, tasteless, excellent sealing, insulation, corrosion resistance, it is widely used. Then, what are the plasticity temperature requirements of the PTFE tape?

The plasticity of the PTFE tape increases with the increase of temperature, while the mechanical properties deteriorate sharply. When the load is higher than 3MPa, the residual deformation occurs; when the load is about 20MPa, the PTFE tape will be crushed; when the operating temperature is over 400℃, the PTFE tape will start to decompose and give rise to a highly reactive poisonous gaseous fluoride.  The low temperature performance of the PTFE tape is good and the flexibility can be maintained when the temperature is lower than -80 degrees centigrade

PTFE tape is a polymer, white or gray white translucent material; good chemical stability, not by acid and alkali corrosion, do not burn, do not dissolve in any solution, water will not be infiltration; has excellent electrical insulation properties, high speed machining; can withstand 200 degrees temperature, long time working at l00℃ -120 ℃temperature range, room temperature outgassing rate than ordinary rubber, friction coefficient of the steel is 0.02-0.1, can be used for vacuum sealing; PTFE tape with sleeve packing with lubricant must do. In order to reduce the friction coefficient of PTFE tape, it is necessary to ensure good thermal conductivity avoid damaging the friction.
