How to control quality of Teflon tapes under processing ? (1)

Some people have one question, how to control quality of Teflon tapes under processing ? What's factors on the quality of PTFE tapes ?

Now PTFE tape supplier will tell you the truth  about how to control quality of Teflon thread seal tapes.

Teflon tapes products quality depends on many factors, such as raw material quality, heating time, straightness of roller for calendar, stretch ratio, temperature of slitting machine, blade quality, worker’s skills and so on.

First most important factor is PTFE raw powder quality, now PTFE material suppliers always offer different classes material, if PTFE tape manufacturer use lowest class material, the strenching ratio and quality of PTFE tapes must not be good. Most of Teflon tape manufacturers are mixing middle class material with low class together. Their cost can be saved about USD 600/ Ton. 

Sure, some good manufacturer like http://ptfe-tape.com using top class and middle class material for mixing, this product be with high performance and good quality , it is not easy to broken when you using it.

Next time, Teflon  tape supplier will tell you another factor that how to stretch ratio impact the quality of thread seal tapes.

The above information is from Teflon tape manufacturer Amstar Seal Tape Co.,Ltd. and Magstar Machinery Technology Co.,Ltd.

PTFE Plumber’s Tape


Thread seal tape is a polytetrafluoroethylene (PTFE) film used in sealing pipe threads. It is also known by the trade name Teflon tape. thread seal tape lubricates allowing for a deeper seating and tightening of the threads, helping to prevent the threads from seizing when being unscrewed. The tape also works as a deformable filler and thread lubricant, helping to seal the joint without hardening or making it more difficult to tighten, and making it easier to tighten. The tape is typically wrapped around a pipe’s thread three times before it is screwed into place and is commonly used commercially in applications including pressurized water systems, central heating systems, and air compression equipment.

AMSTAR PTFE thread seal tapes meet MIL spec 27730A and are 3.5 mils thick. They are composed of white sintered PTFE and are wound on a blue spool with a white snap-on shell cover. Can-Do stocks PTFE thread seal tapes that are manufactured and imported from the Far East, but domestic products are also popular. These PTFE film products are recommended for use on all threaded fittings for passage of water, gas, oxygen, chemicals, and other fluids or gases.

PTFE tapes price depends on its quality


In recent years, with the development of economy, the sealing industry such as Teflon tape has developed rapidly. However, unlike other industries, although the sealing industry has developed rapidly, changes in the sealing company is slow. The price of PTFE thread seal tape determines the anticorrosion performance is superior, and the overall adhesion is better, the service life is relatively longer.

The overall performance of good quality PTFE plumbers tape is very superior during construction, . It can be cured at normal temperature as the conventional anticorrosive paint. It is relatively simple in construction. For some unfamiliar people, the same can be done. In our opinion, the sealing of the PTFE thread seal tape is also very perfect, and its performance is also very perfect, it can withstand high temperatures, even in more than 200 degree above the high temperature can be used.


In addition, the PTFE tape is also resistant to low temperature, even in the state of one hundred degrees below zero, can also maintain a soft state. At the same time is also resistant to corrosion, whether those organic solvents, will not have any effect on it. In a large number of plastic materials, its aging life is very long. The effect is also very good, there is enough lubrication, and non stick performance is perfect.

Amstar seal tape co.,ltd not only adopts advanced teflon tape machine with high technology, but aslo using top grade high density of ptfe raw material it ensures good quality of products.

Characteristics of Teflon thread seal tape

   Characteristics of Teflon thread seal tape

Teflon Thread Seal Tape has excellent practicability and can be used in many occasions because of its various advantages.

Corrosion resistance - for most chemicals and solvents, exhibits inertia, resistance to strong acids, alkalis, water, and various organic solvents.

High temperature resistance -  using operating temperature of 250 degrees.
Low temperature resistance -  good mechanical toughness. Even if the temperature drops to -196 degrees, 5% elongation can be maintained.

No toxicity - it has physiological inertia. As an artificial vessel and organ, it is implanted into the body for a long time without any adverse reaction.

Weather resistance - the best aging life in plastic.

High lubrication - the lowest friction coefficient in solid materials.

Non adhesion-  the smallest surface tension in solid material and does not adhere to any substance.


Amstar Seal Tape Co., Ltd. is a professional PTFE tape manufacture with advanced technology, equipment and experienced staff, we are not only offer good products but also good service, sincerely look forward to meeting with you, hope we can bring you a different experience.

PTFE Tapes Making Process

Process of PTFE Tape Making Machine 

PTFE Tapes making machines are component of series continuted machines, such as shaking machine, mixing machine, heating oven machine, calendar machine, deoiling machine, streching machine, sliiting machine, rewinding machines, packing machine, injection machine, printing machine and so on. 

The PTFE tapes main making process as following :

Mixing PTFE material with kerosene for half hour at least–––Oven heating baking mixed material for six hours at leastPressing material into round shape first and then press round shape into rope shape by special mould– Using calender machine for making rope shape into to fixed film you requiresSittling to the width you need after kerosene out and high stretching ratioWrapping request length to reelPacking.

The above is PTFE machine information . Hope it can help you understand how to make PTFE tapes.

PE Pipe Extrusion Process (6)

Pullers

The puller must provide the necessary force to pull the pipe through the entire cooling operation. It also maintains the proper wall thickness control by providing a constant pulling rate. The rate at which the pipe is pulled, in combination with the extruder screw speed, determines the wall thickness of the finished pipe. Increasing the puller speed at a constant screw speed reduces the wall thickness, while reducing the puller speed at the same screw speed increases the wall thickness.

Standards of ASTM International and other specifications require that the pipe be marked at frequent intervals. The markings include nominal pipe size, type of plastic, SDR and/or pressure rating, and manufacturer’s name or trademark and manufacturing code. The marking is usually ink, applied to the pipe surface by an offset roller. Other marking techniques include hot stamp, ink jet and indent printing. If indent printing is used, the mark should not reduce the wall thickness to less than the minimum value for the pipe or tubing, and the long-term strength of the pipe or tubing must not be affected. The mark should also not allow leakage channels when gasket or compression fittings are used to join the pipe or tubing.


Most pipe four inches or smaller can be coiled for handling and shipping convenience. Some manufacturers have coiled pipe as large as 6 inch. Equipment allows the pipe to be coiled in various lengths. Depending upon the pipe diameter, lengths of up to 10,000 feet are possible. This is advantageous when long uninterrupted lengths of pipe are required - for example, when installing gas and water pipes.



Pipe four inches or more in diameter is usually cut into specified lengths for storage and shipping. Typical lengths are 40 to 50 feet, which can be shipped easily by rail or truck. The pipe is usually bundled before it is placed on the truck or railcar. Bundling provides ease of handling and safety during loading and unloading.
