63428-83-1 Usage
Chemical Properties
Different sources of media describe the Chemical Properties of 63428-83-1 differently. You can refer to the following data:
1. d 1.18 g cm-2
2. Most nylons exhibit a combination of high melting point, high strength, impact resistance, wear resistance, chemical inertness, and a low coefficient of friction.
History
The first nylon developed (type 6/6) was discovered in 1938 by W. H. Carothers.
Uses
Different sources of media describe the Uses of 63428-83-1 differently. You can refer to the following data:
1. nylons have filled an important role for industry and the consumer in various formulations, shapes, and forms, e.g., oriented fibers, which are subsequently processed into fabrics, fishing line, and other monofilament uses; injection-molded nylons, used as bearings, gears, and other parts subjected to wear and impact; extruded nylon tubing and hose, used in large quantity because of its chemical inertness, high strength, and flexibility; oriented nylon strip used as strapping for packaging, displacing traditional steel strapping; and heavy cast-nylon parts, frequently used in the textile, paper-making, and bottle-handling fields.
2. Tire cord; hosiery; wearing apparel component; bristles for toothbrushes, hairbrushes, paint
brushes (nylon 610); cordage and towlines for gliders; fish nets and lines; tennis rackets; rugs and
carpets; molded products; turf for athletic fields;
parachutes; composites; sails; automotive upholstery; film; gears and bearings; wire insulation; surgical sutures; artificial blood vessels; metal coating;pen tips; osmotic membranes; fuel tanks for automobiles.
Definition
Generic name for a family of polyamide polymers
characterized by the presence of the amide group
–CONH. By far the most important are nylon 66
(75% of U.S. consumption) and nylon 6 (25% of U.S. consumption). Except for slight difference in
melting points, the properties of the two forms are
almost identical, though their chemical derivations
are quite different. Other types are nylons 4, 9, 11,
and 12 (see Grade).
Safety Profile
Questionable carcinogen withexperimental tumorigenic data by implant. Reacts violentlywith F2. When heated to decomposition it emits toxicfumes of NOx
Check Digit Verification of cas no
The CAS Registry Mumber 63428-83-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,4,2 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 63428-83:
(7*6)+(6*3)+(5*4)+(4*2)+(3*8)+(2*8)+(1*3)=131
131 % 10 = 1
So 63428-83-1 is a valid CAS Registry Number.
