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.

What should you consider while applying the ceramic coating and buying the non-stick cookware?

Nowadays, the word 'Ceramic Coating' is common among homemakers.  Even before the delivery of the cooker, most of them will start searching for a reliable ceramic coating manufacturer, such as Shenzhen SOVIFOR Science & Technology Development, for applying ceramic coating to their new cookware. Ceramic coating is celebrated for its clear coating, as it includes a liquid polymer. When the coating is applied to the cookware, the polymer will create a chemical bonding with the paint of the factory. Once the coating is applied, any chemicals, except abrasion, cannot remove it.

In the past, cooking products were provided with polishing for additional shine, but it offers the shine only for a limited period and it will wear off in due course. Both the ceramic coating, as well as polishing, is a time-consuming process to offer the required shine to the cookware. However, ceramic coating is better than polishing in the end, owing to its better finish and long life.

There are many effective coatings, such as water base coating, silicon non-stick coating, solvent-base coating, PTFE coatings, and Teflon coatings to offer you better safety than any other coatings, besides enhancing the glossiness of your cookware and keeping it cleaner for a longer period.

What exactly is a non-stick coating spray?

Any reputed anti stick coating manufacturer will be committed to offering his/her anti-stick products with the highest quality. These products will usually have better properties of non-stick fluoropolymer coatings, making them popular for an eternal variety of industrial uses. This may range from mold discharge agents to food rating nonstick applications, including manufacturing of food processing tools.

These manufacturers will specialize in the anti-stick coating process and will use two types of anti-stick substance that include

Polytetrafluoroethylene: Shortly referred to as PTFE, this anti-stick material is one of the modern anti-stick fluoropolymer coatings. It is the most popular anti-stick products in the world. With a single coat, it is capable of working efficiently at the highest working temperature of any fluoropolymer at 500 degrees Fahrenheit.

Fluorinated ethylene propylene: With the short name FEP, this anti-stick material has the same characteristics as those of PTFE, but it offers better release characteristics for anti-stick applications. This coating is usually used as an anti-stick coating for molds with a working temperature of 450 degrees Fahrenheit.

While manufacturing the products an anti stick coating manufacturer will provide the products with suitable electrical and physical properties that include:

·        ·   Low coefficient of abrasion, ranging from 0.05 to 0.10

·        ·  Low dampness with hydrophobic and oleophobic surfaces to clean easily

·    ·  Unique electrical characteristics, such as low dissipation factor, high dielectric strength, and   extremely high surface resistivity.

   ·  Cryogenic solidity, allowing products to use temperatures as low as -454 degrees Fahrenheit

·     ·  High chemical resistance, making the products resistant to almost all chemicals, except highly reactive fluorinating agents and molten alkali metals

·        ·  Maximum heat resistance of 500 degrees Fahrenheit with enough ventilation 

    When considering the best coating cookware, the ceramic coating will promote healthy cooking by applying less oil to food items.

A non stick coating spray is mostly used to recoat the damaged anti-stick surface of the products. Most anti-stick cooking pots are recoated with a Teflon layer, allowing you to cook your foods without concerning about their sticking.

You can repair your anti-stick pans yourself to make them look similar to a new one. As non-stick pans will last for a maximum of three to five years, they may require a periodical repair if metal cooking tools scratch them. This is for the reason that when you are using grave vegetable oils for cooking your foods, they may leave a deposit that can have an effect on the anti-stick performance of the cookware. This is particularly true when you use olive oil for cooking your foods. This is for the reason that the olive oil has a stronger flavor when compared to that of vegetable oils.

However, you will be capable of eliminating the anti-stick coating from the cookware completely, leaving a clean, smooth surface. The look and effectiveness of a worn out anti-stick pan can be reinstated easily and effectively without damaging its underneath surface.

Instead of using non stick coating spray, you can consider using some durable and high-quality anti-stick cooking sprays. You can just stroke the coating, butter side down, all over the dish/pan you want to lubricate. Really, it is an ideal solution.
