Heat Shrink PTFE Tubing for Electrical Works

Shrinking under high temperature is nature of plastic and rubber materials and electronic items are not an exception to it. Since your childhood, you would have seen electronic wires coated with plastic or rubber covers which are mainly because plastic and rubber are considered as bad conductors of electricity, is applied to protect the humans from the current. Well, this is about the normal wiring that is installed at our places but despite of this, there are various type of wiring system which is used in industries. Normally, this type of wiring system is protected or covered by tubes which is mainly applied on them to protect them from any kind of explosion, which might arise as an impact of heat generated between the wires during operation.

PTFE Heat Shrink Tubing system is a self explanatory term which normally refers to the tubing system that protects wiring system from explosions during the operation. In simple words, PTFE Tubing is a kind of tubing system which comprises of normal wire attached with an adhesive. Normally, this type of tubing system is developed in ratio of 2:1 and 4:1. The adhesive which is applied on wires when melts due to heat generated from wires, acts as cover to protect the wires.
PTFE tubing is a kind of Fluoropolyer Tubing System which is capable of performing under high temperature and explosive atmosphere. As a general practice, this type of tubing system is used in industries where electronic work is performed for long hours without any stoppage. The worth mentioning feature of this tubing system is that it can chemically sterilized and autoclavable. It is a non-wetting and self-oiling element
This type of tubing system is mainly used by telecommunication industries, protecting wires installed in aerospace during all types of atmospheric conditions, and also in industries where chances of explosion and corrosion occurs.

The logic for inserting these small wires in these tubes is to protect diffusion between wires which get hot while regular operation of these devices. During your childhood you would have read the principle of negative and positive that, when current flows between positive and negative points and when two positive points mix with each other they diffuse. So when temperature crossing from these wires reaches to its peak they start melting and when two or more wires of same point meet each other they start burning and might even result in severe electronic accident. To protect such unfortunate accidents, use of excellent Heat Shrink PTFE Tubing system is used that is protect this mixture of wires even at high temperature.
The Heat Shrinkable FEP Tubing system is not only used on electronic devices but even in industries where heavy machines are used for production of various gaseous and chemicals. This type of tubing system not only makes smooth flow of elements from one point to another but also protects any type of damage to tubes which might take place as an impact of their rough use.

Heat Shrink FEP Roll Covers to Protect Rollers and Eliminate Build up.

In simple words, Heat Shrink FEP Roll Covers is defined as a covering system that is applied on rolling elements that are involved in some productive applications. Industries like textile, paper processing, food packaging, photocopier etc develop the products in layers which are placed in bundle format above each other. And, the item that helps in smooth layering of their output is known as roller. With an objective to extend the life of roller and to protect any type of damage to the products from heat and other products, the element that is used to cover the roller is known roll cover

The features like zero moisture absorption, chemical resistance, and anti-stick release adhered in FEP tubing system are helpful to protect the products that are manufactured by these industries. An interesting feature of FEP roll cover is that it is easy to clean with piece of damp cloth.
The major features of Heat Shrink FEP Roll Covers are referred below:
  • Flexibility
  • Low maintenance
  • No sticking
  • Heat resistance
  • Chemical resistance
  • Minimizes cost of labor.
Developed from fluoropolymer, FEP roller cover has an efficiency of operating smoothly under extreme hot temperature up-to 500°F. The roll cover has thickness of 0.20 inch with diameter varying from half inch to 12 inches and has length up-to 10 feet. If an industry where operating temperature is above 500°F and the operation is conducted at high speed under extreme pressure, it would be better to etch and bond the cover to roller. Etching roll covers are developed from special type of adhesives which is applied on rollers to control any type of damage to final product. Application of FEP roll covers on rubber rollers is helpful in protecting them from instant damage which might take place due to excess of heat generation during operation.

Corrugated FEP Tubing: High Temperature Chemical Resistant Option for Cable Protection

The use of Corrugated FEP Tubing came into existence for first time in 1966 when it was developed by an expert Ira Clement working at Penn Tube Plastics. The main reason of this tubing system was felt necessary for making smooth transition of hazardous chemicals and acids while they were transmitted from one corner to another, crossing deep curve through bends at various places and without making any impact to inner diameter. At the beginning, this tubing system was mainly used in bottle filling lines because of its best compression efficiency but in later years it became an integral part of chemical and acid industries.
Developed with help of either PFA or FEP resins which is compatible to FDA Corrugated FEP Tubing can be used in robots which constitute an important source of operation in industries which are involved in production of chemical and acids. Use of this tubing system is helpful in developing flexible hands and arms of robots.

Spiral Wrap Facilitating Flexibility to Wires and Cables

Spiral Wrap PTFE
While visiting any shop of electronic equipments or any computer learning institute, you would have noticed bunch of electronic cables and wires kneaded with each other inside a tube or spiral wrap that is capable of moving in any direction offering complete flexibility to wires along with providing protection from any kind of abrasion. Now, the reason arises that why these wires and cables were blended in tubing system rather them lying openly on floor. Well an answer to this simple question is to protect any kind of accident which might take place due to heat generated by wires while they are switched on. Moreover there are chances when due to any cut in these wires they may get attached with each other and might result in incidences of short circuit resulting in huge loss in term of life and money.
To control such incidences, different types of wires protecting systems have been developed by manufacturers but interestingly use of Spiral Wrap PTFE has emerged as the best solution of this problem. Because of its noteworthy features like efficiency of operating smoothly under extreme temperature going high up-to 500°F, self extinguishing and RoHS compliance, this tubing system has become the first choice of almost all business operators for managing cables and wires installed in their organization.
The spiral cut tubing is developed by making use high quality fluoropolymer tubing which make it durable and flexible for offering complete protection to cables and wires. An interesting feature of spiral tubing system is that like spiral binding that is used in binding books this tubing system also moves from upward to downward or vice-versa. It is easier to install and as it carries the important characteristic feature of teflon that is non-sticky nature it does not get attached to wires because of heat generated by them.

Various Forms of PTFE Used in Aerospace and Aviation Industries

Teflon PTFE Tubing
Installation of PTFE tube has become an indispensable activity for every organization to conduct operating activities smoothly and protect the web of wires from any kind of accident. Often, known as polytetrafluoroethylene, in the beginning the PTFE was used only in specific industries. However it was back in 1950, because going through its versatility, soon became an integral part of almost every industry especially in aerospace where it is used in filling fuel in aircraft, tubing hoses , hydraulic hose, protecting doors and making easy assembling of aluminum and other metals followed by complete protection from any kind of damage.
Interestingly, the use of the Teflon PTFE Tubing in aircraft is not stagnated only upto the above mentioned activities but, is also used in various applications for instance in edges of wings mounted on the aircraft. The low coefficient of friction feature found in it, which makes the aluminum rod installed in wings flap and slat smoothly while landing. Moving ahead, the Teflon PTFE starts acting as sheet of protection at the time when an aircraft lands. In absence of this fluoropolymer plastic, it is possible that aluminum rod might break during landing when it is starts coordinately with other wings.
