The name "nylons" refers to the group of plastics known as polyamides. Nylons are typified by amide groups (CONH) and encompass a range of material types (e.g. Nylon 6,6; Nylon 6,12; Nylon 4,6; Nylon 6; Nylon 12 etc.), providing an extremely broad range of available properties. Nylon is used in the production of film and fibre, but is also available as a moulding compound.
Nylon 6.6 has good abrasion resistance and is self-lubricating, which makes it a good engineering material. It is also widely used as a fiber in carpeting, clothing, and tire cord. For an interesting account of the development of Nylon, see Enough for One Liftetime: Wallace Carothers, Inventor of Nylon by Ann Gaines (1971)
Nylon Types and Uses. We have mentioned some of the many types of nylon and the following set are a few that are used in everyday life-- Nylon-6, Nylon-6,6, Nylon-6,10, Nylon-6,12, Nylon-11, Nylon-12, and Nylon MXD6. The last one is the newest member of the list of types of nylon. As for their individual uses, those are usually listed ...
Bakelite was invented in the early twentieth century but it is an important topic of study even in this 21st century. The properties of Bakelite are studied to get information regarding its commercial usage. The physical, chemical, electrical and thermal properties of Bakelite make it a widely used commercial polymers.
Nylon 6 and Nylon 6/6 – have very similar mechanical, thermal, and electrical properties. Both are available in a variety of colors and formulations that are engineered to meet specific application requirements. Nylon 6 – is generally manufactured into sheet, rod, and tube via a liquid casting process.
A good example is Nylon 6/6. The polymerization of Nylon 6/6 is shown in Fig. 1.1. Nylon 6/6 is actually an alternating copolymer polymerized from monomers of adipic acid and hexamethyl diamine. Although it is a copolymer, the structure on the right side Fig. 1.1 can be viewed as the single repeat unit for Nylon 6/6.

In figures 4 and 5, the rate of volatilization data were obtained on different molecular weights of the nylon-6 sample. The temperatures in all cases are higher than that used for the previous nylon copoly mers.
Composition of nylon-6 and 5-25% fine particle size, waxy PTFE/0.01-10% nucleating agent for alpha crystallization of the nylon-6 ingredient. The composition is useful as a sleeve bearing for steel cable by virtue of its low friction and high wear resistance against such cable and the ease of extruding it from the melt to produce a flexible tube.
Nylon 6 is an awful lot like our friend nylon 6,6. You can look at the picture if you don't believe me. But making nylon 6 is lot different from nylon 6,6. First of all, nylon 6 is only made from one kind of monomer, a monomer called caprolactam. Nylon 6,6 is made from two monomers, adipoyl chloride and hexamethylene diamine.
Nylon is a family of fibres, not a definite fiber itself, but the most common nylon is Nylon-66 Nylon-66 is a polymer of adipic acid (COOH-CH2-CH2-CH2-CH2-COOH)and hexymethylene diammine. (NH2-CH2 ...

Nylon 6 and 66 belong to polyamide group and resembles in physical as well as chemical nature; higher crystallinity, better molecular orientation and melting temperature of nylon 66 is higher than those of nylon 6. Being more crystalline, rate of dyeing of nylon 66 is relatively slower with reasonably better fastness of dyeings.

What chemicals make up nylon? Nylon is a polymer, that is, a macromolecule made up of many, smaller molecules (monomers) that are bonded together and are the same. Technically speaking, nylon is a condensation polymer.
In the formation of nylon 6,6, we react a molecule with an amine group on each side known as hexane-1, 6-diamine and a molecule with a carboxylic acid at each end, hexanedioic acid. Since both these molecules have long chain carbons, they are only complicated the visual structure. Let us remove these and replace them with rectangular blocks.
Nylon 6 and Nylon 6/6– have very similar mechanical, thermal, and electrical properties. Both are available in a variety of colors and formulations that are engineered to meet specific application requirements. For Nylon 6 chemical resistance view our chart.

Nylon was the first synthetic fiber manufactured in the US. It is made from polymers consisting of carbon, oxygen, nitrogen, and hydrogen. Nylon is a versatile fiber used in clothing, carpet, and tires. nylon nylon fiber. 2 24,798. Share Facebook Twitter ReddIt WhatsApp Pinterest Email.
Today, nylon is an alternative designation for polyamides and their immediate chemical derivatives and copolymers, but the term polyamide should be preferred. To circumvent the DuPont patents, German chemists in the late 1930s developed and introduced the polyamide 6, and now PA 6.6 and PA 6 account for nearly all the polyamides produced for ...

Description. A general name for a family of synthetic long-chain polyamide resins. Nylons are classified with system in which the word nylon is followed by a numeral indicating the number of carbon atoms in the monomer, such as Nylon 6.When two numbers follow, such as nylon 6,6, the polymer was made from a diamine (first number) and a dibasic acid (second …

Nylon is commonly referred to using the chemical designation "PA" (e.g., PA 6 or PA 6/66) and is most widely available in black, white, and its natural color (off-white or beige). Perhaps the most common variant for engineering applications is Nylon 6/6. Nylon 6/6 can be extruded (melted and forced through a die) and is also a suitable ...
Choose from hundreds of manufacturing materials including various grades of thermoplastics, metals, and elastomers. When selecting a material, consider the material properties, manufacturability characteristics, cosmetic appearance, and cost. For milling and turning dimensions by material, please see maximum part extents for machining.
Chemical Composition Its properties are determined by the R and R' groups in the monomers. In nylon 6,6, R' = 6C and R = 4C alkanes, but one also has to include the two carboxyl carbons in the diacid to get the number it donates to the chain. A.K.A. Polyamides, PA Properties
Nylon 6, produced via the ring-opening reaction of the compound caprolactam is structurally similar to nylon 66 and has similar properties and uses. It is widely used in Europe in place of nylon 66, but not in the United States. (See Figure 5.) Nylon 6,10 and nylon 6,12 are also commercially available.
For example, nylon -6, 6. Thermoplastics: These have intermediate forces of attraction. For example, polyvinyl chloride. Thermosetting polymers: These polymers greatly improve the material's mechanical properties. It provides enhanced chemical and heat resistance. For example, phenolics, epoxies, and silicones. Structure of Polymers
Nylon fabric is a polymer, which means that it is composed of a long chain of carbon-based molecules called monomers. There are quite a few different types of nylon, but most of them are derived from polyamide monomers that are extracted from crude oil, which is also known as petroleum.
Chemical Properties of Nylon 6: Chemical properties of nylon 6 are given below. Acids: Like nylon 6.6, nylon 6 has not enough ability against acidic action. Basic: Basic does not cause harm to the nylon 6. Nylon 6 has enough ability against alkali. Effect of bleaching: Strong oxidizing agent is harmful for the nylon 6.
Behind the scenes the invention of nylon also transformed the chemical industry by proving that the composition of polymers could be predicted and engineered like many other chemical products. Today nylon—in toothbrushes, carpet, racket and guitar strings, surgical sutures, car parts, and, of course, hosiery—is all around us. A Pure Discovery
