All you need to know about PTFE coating

PTFE or Polytetrafluoroethylene coatings are fluoropolymer coatings that are capable of offering better non-stick characteristic in a very tough skinny film coating. The PTFE coating is usually used where an even, low friction, rust resistant coating is required. This type of coating has been in practice for the last seven decades.

Polytetrafluoroethylene coating is actually a fluorocarbon solid, making it opposed to acidic chemicals and high temperatures for both cold and hot, ultraviolet rays, and low abrasion. The coating is also capable of providing the best padding from electricity and it will never absorb water. The legacy of PTFE coating in industrial uses spans more than 80 years.

According to the manufacturers, the PTFE non stick coating for cookware will offer them better non-stick release than conventional non-stick cookware.  They claim that the PTFE coatings are robust, scratch as well as scrape resistant, and they will never corrode.

Actually, people either love PTFE coating or hate it.  For some people, the coating will perform well for many years, while for others it will lose its non-stick characteristics quickly, despite their utmost care and caution.  Many users of PTFE coating cookware found that the life of the non-stick part of a PTFE coated pot or pan is one year. This is chiefly because of poor maintenance and care.

The PTFE non-stick coating cookware and kitchenware will have the peak operating temperature of any fluoropolymer. They will also have an extremely low friction coefficient, good chemical resistance as well as abrasion resistance. One of the most popular applications of Polytetrafluoroethylene coatings is for non-stick need or any application the needs a food grade covering.

PTFE coating cookware is one of the most preferred non-stick products in the world. This type of coating has exceptional release characteristics and capable of withstanding temperatures up to 500 degrees Fahrenheit. The Polytetrafluoroethylene coating is normally applied to a thickness of about one mil.

The unique structure of a PTFE coating is what offers it the non-stick, non-abrasion, and dielectric characteristics, making it constructive in so many applications. The coating is a fluorocarbon firm, meaning that it has a lofty molecular weight made up exclusively of fluorine and carbon. This composition gives the coating a great resistance to water, offers it a low abrasion coefficient, and makes the coating other helpful characteristics possible.

The applications of Polytetrafluoroethylene coating are limitless. Although it acts as an efficient and resourceful non stick coating for cookware, it is also used in the manufacturing of computers as well as airplanes. The dielectric properties, as well as the high thawing temperature of the PTFE coating, makes it perfect for connector assemblies and insulation cables. This coating is used as insulation while manufacturing Printed circuit boards with high microwave frequencies. Due to the excellent insulation properties of PTFE coating, it is extensively used in many industries to get better results.

Safety Secrets of Ceramic Coated Cookware

There are many opinions on cookware coating whether it will be non-toxic, safe to use, easy to clean and maintain, etc. While Teflon coating has had its contribution to negative advertising, there have been lot question marks, as well, about cookware that comes with the ceramic coating.  Concerns mostly comprise the likelihood of toxins and metals, such as cadmium, lead, and arsenic leaching into the food. There is even doubt on the non-stick feature of the ceramic coating.

The marketer, as well as the ceramic coating manufacturer, claims that the ceramic-coated pots and pans are ultra safe, without heavy metals or chemicals and that, they are extremely durable. However, how far their claims are true mainly counts on the opinion and the personal experience of their users.

Technically, ceramic refers to clay that has been hardened through burning it by fire, so when comes to ceramic coated cookware, it refers to some kind of metal, typically hard anodized aluminum, which has been coated with a ceramic layer.  The ceramic non-stick coating is usually prepared from inorganic minerals, chiefly oxygen and silicon, meaning the coating does not contain any carbon. This indicates that the cookware that comes with the ceramic coating will be free from PFOA and PTFE. A ceramic coating manufacturer will use only inorganic materials to produce the ceramic-coated cookware and the composition will be essentially the same as stone or sand.

Additionally, ceramic makes the manufacturing process quit simpler. Unlike PTFE based non-stick coatings that need a minimum of three applications, ceramic coatings need only one layer.  Ceramic needs less time to treat, as well, which decreases the oven time, saves power, and releases 50% less carbon dioxide than the products that are manufactured using PTFE.

Sol-gel is the process involved while manufacturing ceramic-coated cookware and kitchenware. The process will change the inert liquid Solution into a Gel, which can be applied to any metallic matter.  Sol-gel coatings are used either by dipping the item or by spray in the mineral gel. This is then hardened by curing, which is a process that involves high heat firing.

The major benefit of using the ceramic cookware coating is that it will have immense resistance to heat. The cookware will be capable of tolerating maximum heat of 450 degrees Centigrade, as ceramic is inorganic in nature.

According to a ceramic coating manufacturer, even if you heat a ceramic-coated pot or pan by chance beyond 450 degrees Centigrade, it will not release any toxic smokes, unlike a Teflon coated pot or pan.  It will not even break down, as well, meaning ceramic-coated pans or pots are safe to use.

There have been complaints on some ceramic coatings that leak cadmium or lead into food.  This is naturally true of ceramic cookware from Asian and Latin American countries where rules may be a bit slack.  In other countries like India, there are strict manufacturing principles for ceramic products to be free of cadmium or lead.  All reputable ceramic coating manufacturers should obey or are supposed to abide by these requirements.
