Silverstone (plastic)
SilverStone is a non-stick plastic coating made by DuPont. Released in 1976, this three-coat (primer/midcoat/topcoat) fluoropolymer system formulated with Polytetrafluoroethylene, PTFE and PFA produces a more durable finish than Teflon coating. As of 1980 Dupont required that the pans carrying the brand be a heavier weight than others on the market. After the coating was applied the cookware was subsequently "baked" in a 700-800 degree oven to affix the coating. The process for creating Silverstone cookware begins by sandblasting the products which creates an uneven surface that encourages adherence. Then a primer layer of Teflon is sprayed on and after it is baked at high heat to "a secure mechanical grip." Gizmodo reported in 2014 that one or two more additional layers were applied after the initial layer.

Non-stick
A non-stick surface is engineered to reduce the ability of other materials to stick to it. Non-sticking cookware is a common application, where the non-stick coating allows food to brown without sticking to the pan. Non-stick is often used to refer to surfaces coated with polytetrafluoroethylene (PTFE), a well-known brand of which is Teflon. In the twenty-first century, other coatings have been marketed as non-stick, such as Anodizing#Anodized aluminium, anodized aluminium, silica, Cast-iron cookware#Enameled cast iron, enameled cast iron, and Seasoning (cookware), seasoned cookware. Types Seasoning Cast-iron cookware, Cast iron, carbon steel, stainless steel and cast aluminium cookware may be seasoned before cooking by applying a fat to the surface and heating it to polymerize it. This produces a dry, hard, smooth, hydrophobic coating, which is non-stick when food is cooked with a small amount of cooking oil or fat. Fluoropolymer The modern non-stick pans were made using a ...

Plastic Coating
Plastic coating is a term that is commonly used in technology but is nevertheless ambiguous. It can be understood to mean the coating of plastic (e.g., metallization of plastics) or the coating of other materials (e.g., electrical cable) with plastics. Polymer coating A polymer coating is a form of plastic coating or surface coating and consists of a plastic base. There are also tribological polymer coatings that can be adapted to numerous application needs thanks to the variety of polymers available. The coating reduces friction and abrasion, thus preventing the product from wearing out due to corrosion and scratching. Advantages Coatings made of polymers can be produced from various compounds. They can therefore be applied to almost any surface. Polymer coatings are accordingly particularly suitable for places where plain bearings cannot be used. A tribological coating can be used, for example, where space is limited and access is difficult. In addition, polymer coatings ...

Fluoropolymer
A fluoropolymer is a fluorocarbon-based polymer with multiple carbon–fluorine bonds. It is characterized by a high resistance to solvents, acids, and bases. The best known fluoropolymer is polytetrafluoroethylene under the brand name "Teflon," trademarked by the DuPont Company. History In 1938, polytetrafluoroethylene (DuPont brand name Teflon) was discovered by accident by a recently hired DuPont Ph.D., Roy J. Plunkett. While working with tetrafluoroethylene gas to develop refrigerants, he noticed that a previously pressurized cylinder had no pressure remaining. In dissecting the cylinder, he found a mass of white solid in a quantity similar to that of the tetrafluoroethylene gas. It was determined that this material was a new-to-the-world polymer. Tests showed the substance was resistant to corrosion from most acids, bases and solvents and had better high temperature stability than any other plastic. By early 1941, a crash program was making substantial quantities of PT ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polytetrafluoroethylene
Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene, and has numerous applications because it is chemically inert. The commonly known brand name of PTFE-based composition is Teflon by Chemours, a corporate spin-off, spin-off from DuPont (1802–2017), DuPont, which originally invented the compound in 1938. Polytetrafluoroethylene is a fluorocarbon solid, as it is a high-molecular-weight polymer consisting wholly of carbon and fluorine. PTFE is hydrophobic: neither water nor water-containing substances Wetting, wet PTFE, as fluorocarbons exhibit only small London dispersion forces due to the low polarizability, electric polarizability of fluorine. PTFE has one of the lowest Friction#Coefficient of friction, coefficients of friction of any solid.

Plastics
Plastics are a wide range of synthetic or semisynthetic materials composed primarily of polymers. Their defining characteristic, plasticity, allows them to be molded, extruded, or pressed into a diverse range of solid forms. This adaptability, combined with a wide range of other properties such as low weight, durability, flexibility, chemical resistance, low toxicity, and low-cost production, has led to their widespread use around the world. While most plastics are produced from natural gas and petroleum, a growing minority are produced from renewable resources like polylactic acid. Between 1950 and 2017, 9.2 billion metric tons of plastic are estimated to have been made, with more than half of this amount being produced since 2004. In 2023 alone, preliminary figures indicate that over 400 million metric tons of plastic were produced worldwide. If global trends in plastic demand continue, it is projected that annual global plastic production will exceed 1.3 billion tons ...

Lubricants
A lubricant (sometimes shortened to lube) is a substance that helps to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces. The property of reducing friction is known as lubricity. In addition to industrial applications, lubricants are used for many other purposes. Other uses include cooking ( oils and fats in use in frying pans and baking to prevent food sticking), to reduce rusting and friction in machinery, through the use of motor oil and grease, bioapplications on humans (e.g., lubricants for artificial joints), ultrasound examination, medical examination, and sexual intercourse. It is mainly used to reduce friction and to contribute to a better, more efficient functioning of a mechanism. History Lubricants have been in some use for thousands of years. Calcium soaps have been ide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
