PTFE Recycling Facts

Did you know? PTFE was discovered by DuPont, a research chemist in the year 1938. In 1941 it has been patented. According to Environmental Protection Agency (EPA) about 12,000 BTU’s of heat energy by recycling one pound of plastic pet bottles. 

With the rapid increase in global marketing, there is a wide use of plastic as an alternative material. The demand can be met from recycled plastic. Use of plastics has the capability to cause danger to both environment and human life.

In order to avoid this, Environmental Protection Agency (EPA) had taken up an action to recycle all the PTFE materials. Even the American society of plastics have identified and differentiated various types of plastics which is given a category number.

Need of PTFE has increased over the years, which are used in industries such as automotive, medical, food packaging, household and personal care. They are generally opaque and have good heat resistant characteristics. PTFE can be recycled into many other products and used for rods, tubing and sheets. It can be sterilized by using autoclave, gas, dry heat and chemical disinfectant. The recycled PTFE (known technically as “Reprocessed” or “Repro” PTFE)

Recycling Process of PTFE

Recycling of PTFE became common in industries as there is no chemical reaction is required. The PTFE scrap is grind into fine powder and then blend with pure PTFE that is used in compressions molding. To remove the inorganic compounds the scrap is first heated before grinding. Only the extruded forms can be recycled and separated from unwanted impurities and heated. Next it is put into a long strand, which is then cut down into small pallets and sent to industries that use as recycled material for their products.

Uses of Recycled PTFE

Most of the PTFE products are ground into powder which is used in inks, paints and cosmetics. Fiber filling for ski coats, fleece coat, polyester suits and more for cold areas is very prominent in developed countries. PTFE recycling reduces greenhouse gas emissions and save the environment. It’s even used for making plastic lumber, toys, park benches, car parts, drainage pipes and more. The recycled materials are graded as per plastic inputs by companies like ECO USA.

Economic Conditions of PTFE Recycling

PTFE recycling appears to be economic, which saves about 7.4 cubic yards of landfill space. Its saves 12,000 BTU’s of heat energy by recycling one pound of plastic bottles. Oil consumption can also be reduced by recycling all the scrap plastics. The price of PTFE resins had reached some stability level globally.

Eco USA is a leading PTFE recycler who effectively removes PTFE scrap from your production line. We specialize in the development and production of high quality PTFE products. The company identifies three grades of PTFE scrap for specific uses.

ECO USA encourages more clients to work with in order to develop recycling solutions for their scrap and rejected goods by doing waste stream analysis. We help you to recycle the maximum quantity of materials for different uses. Once the materials are fed though the shedders or steam machines we issue a certificate of destruction.

If you are looking for the best 100% customer satisfied PTFE recycling solution provider, you can directly contact one of your known companies or else call ECO USA right now to build long time relationship by getting high-quality PTFE recycling results.

PTFE Charactersitics

PTFE (Polytetrafluoroethylene) plastics are generally opaque, and are an excellent barrier to gas, moisture, and resistance to heat. PTFE shows a remarkable chemical resistance and it is insoluble in all known solvents. It is attacked only by molten alkali metals and fluorine at high temperatures. PTFE has excellent resistance to acids, alkalis and solvents. It is very lubricous, with the lowest coefficient of any polymer. The chemically inert plastic is easy to clean and has exceptional mechanical resistance under extreme conditions. In addition, PTFE is autoclavable and non-flammable.

PTFE for Laboratories

PTFE is a good choice for labware because of its many desirable characteristics. PTFE is useful because of its resistance to corrosive elements that many other plastics are unable to stand up to. The anti-stick properties and low coefficient of friction of PTFE are desirable qualities for durable labware. PTFE can be sterilized by autoclave, gas, dry heat and chemical disinfectant.

PTFE Recycling

PTFE does not have it’s own recycling code symbol. However, PTFE can be recycled into many other products. Recycled PTFE can be used for rods, tubing, tape and more.

PTFE’s Role in History

PTFE was first discovered accidentally in the 1930s by DuPont scientist Roy Plunkett. It was first used to store highly corrosive elements for the Manhattan Project during the 1940s, in which the first atomic bomb was developed. In the late 1940s DuPont commercialized PTFE. Since then, several companies have made advancements upon the plastic resin in many avenues, such as laboratory equipment, non-stick cooking surfaces and engineering industries.

PTFE Grades

ECO U.S.A is a leading PTFE recycler with the goal of effectively removing PTFE scrap from your production line. Hence, we are always in the market for new sources of scrap from PTFE products including cores, rods, tubes, sheets, and other parts. We categorize and price PTFE scrap by grades and usability:

  • Grade A PTFE Scrap – The ideal type of PTFE Scrap, Grade A is to be clean and derived from virgin PTFE. Such PTFE type is unmodified, and without pigment and fillers. Examples of such Grade A scrap usually derives from obsolete parts, tubes, rods, cores, heavy tape punchings, and clean machine turnings without oil contamination.
  • Grade B PTFE Scrap – Grade B PTFE scrap is clean and derived from partially-reprocessed or fully-reprocessed PTFE. Some easily removable contaminates are allowed.
  • Grade C PTFE Scrap – Grade C PTFE scrap, is usually derived from products such as repressed PTFE, etched or degraded virgin. Other scrap under this category will contain hard-to-remove contaminates, such as rusty valve seats and gaskets. Heavy oil contamination from machine turnings also falls under this grade.

Unusable PTFE Scrap

We aim to recycle all and every ounce of PTFE scrap we collect, however, as it is difficult to remove excessive oils and other deeply embedded contaminants, proper care must be taken during your collection and storage process. Contaminated scrap will greatly reduce usability and cause entire container loads of PTFE scrap to be unusable.

Our air milling and separation facilities can produce micronized PTFE down to a 3 micron particle size or custom grind per request, verified by laser refraction in the lower micron levels. We run only PTFE in our equipment, avoiding contamination with other polymers.

Plastic Recycling Machine

As the United States increase in the amount of plastics used in manufacturing products such as bottles, bags, toys, and furniture, the subject of plastic recycling and end-life management has become evermore important. According to the Environmental Protection Agency (EPA), plastic consists of 12.4% of all municipal solid waste in 2010, that’s around 31 million tons. Of this, only 8% was recycled.

The remaining 92% of plastic waste, or approximately 28.5 million tons, in the municipal solid waste stream is landfilled. With this number on the increase and landfills filling up quickly, efforts in developing plastic recycling technology have rapidly strengthened. The largest problem faced by plastic recyclers is that plastic need to be separated by type before it can be properly recycled. That is, PET plastic bottles cannot be mixed with plastic films made from LDPE. These two types of plastic cannot be recycled or melted together as PET bottles have a higher melting point than LDPE film. To resolve this, separation machinery must be used.

According to one manufacturer plastic recycling machines, the separation of PET from LDPE is quite simple using a gravity “sink / float” separation tank. PET bottles and LDPE films are first be cut down into small pieces or flakes using a plastic granulator or industrial shredder. This mixture of material is then placed into a large separation tank filled with water. As PET plastics have a higher density than water, it will sink to the bottom while LDPE, with density less than water, will float to the top. Using a conveyor system, the PET at the bottom of the separation tank is removed and further processed.
