Nylon 6,6 (nylon 6-6, nylon 6/6 or nylon 6,6) is a type of polyamide or nylon

Preparation, Properties and Applications of Nylon 6 ..

Nylon 6/6 is a semi-crystalline polyamide composed of polyhexamethyleneadiptimide. Nylon 6 and Nylon 6/6 are the two most common grades of nylon manufactured. The number refers to the number of carbons that occur on each side ofthe amide groups, or nitrogen atoms.

made and then used in the commercial synthesis of nylon 66

There are many types of nylon available (e.g. nylon 6, nylon 66, nylon 6/6-6, nylon 6/9, nylon 6/10, nylon 6/12, nylon 11, nylon 12). The material is available as a homopolymer, co-polymer or reinforced. Nylons may also be blended with other engineering plastics to improve certain aspects of performance. Nylon is well suited for processing via injection moulding, rotational moulding, casting or extrusion into film or fiber.

Plastics make up a major category of the polymer field. The world plastics market was about 622 billion pounds in the year 2014. The plastics industry is the third largest manufacturing industry in the United States. In 2014, more than $427 billion in plastic goods were shipped. Most of these materials are a synthetic commodity and engineering resins and the major types are listed below. From Nylon 6/6 testing, to ABS and PET testing, Polyhedron has the capbilities to peform thousands of plastics tests. Polyhedron Laboratores has been performing an extensive number of tests for over 40 years.

Synthesis of polyaniline nylon 66 conducting composites

Nylon 6/6 is used mainly in fiber applications such as carpeting, clothing and tirecord due to its high wear resistance. Its high abrasion resistance and self-lubrication characteristics make it an excellent material for bearings, gears and other high-wear parts and components.

Preparation and properties of nylon 66 copolymers …

Nylon 6/6 is a semi-crystalline compound. As a result, it has high tensile and flexural strength which results in a material that is wear, chemical and thermal resistant. It also exhibits high abrasion resistance and self-lubricating properties. Nylon 6/6 has a yield strength of 6500-8500 psi.

Polymer Synthesis of Polystyrene and Nylon-6,6 - Google Sites

Nylon-6,6 forms at the boundary between the two solutions. If you pick up the boundary layer with a pair of tweezers, you can pull out an amazingly long tube of nylon from the beaker.

Polymer Synthesis of Polystyrene and Nylon-6,6

For use as an engineering plastic, polyamides are often compounded with fillers, pigments, glass fibre and toughening agents to give specific properties to the polymer. However, for either continuous filament or staple fibres, which are melt spun at very high speeds (ca 6 km every minute), there is great emphasis on controlling the polymer chemistry and the way the yarn is produced in order to ensure the production of the high quality material needed for particular purposes. For example, the thread for use in stockings needs to be strong, as well as very fine, so the molecular mass and hence tensile properties of the polymer must be carefully controlled.
