Nylon granules is a polyamide type. And is one of the most widely used polymers in the public.
Nylon is a kind of thermoplastic made of soft materials. The first commercial use of nylon was to brush toothbrushes and stockings. It is the first successful polymer in the trade.

Nylon 6 and nylon 6.6 are the most important polyamides that also use in the textile industry and in carpet and carpet production. So let’s introduce their properties.
The Nylon 6 or poly-caprolactam was produced when improving nylon properties 66. It is a semi-crystalline polyamide. Unlike other nylons and nylon 66, nylon 6 is a condensation polymer that makes it different from other nylons.
The nylon 6 features can be hard to see, high tensile strength, brightness and elasticity (appropriate elasticity). Nylon 6 is also resistant to chemicals such as acids and alkalis, wear and wrinkles.
Nylon 6 is used in the production of lime, for the production of resin and film production. Today, due to its high strength, more applications have been made to use nylon 6. Including for manufacturing parts in the automotive industry (such as gears, fittings, bearings) and …
Nylon 6 is used as a toothbrush, surgical suture, wire for acoustic and classical instruments such as guitar, violin, cello, and so on. It is also used in the manufacture of all kinds of ropes, strings, tire cables and … and also in socks and knitted garments.
This semi-crystalline polyamide has a tensile strength, elasticity, anti-wrinkle, abrasion resistance and chemical resistance against acids and openings. Good color reproduction is one of the most prominent features of this polymer. Nylon 6 has good hydraulic stability, low cost of production and production, and has a very good performance in thermal tests than nylon 6.6. Nylon 6 use in the aircraft and automobile industry, tour manufacturing, consumer goods and industry, rope, clothing, musical instruments (tar, three voices), electronic and electrical industries.
The Nylon 66
Nylon 6.6 produce for textile and fiber production, and the remainder use to produce resins.
Due to its 3-D structure, nylon 6.6 has high mechanical strength, strength, good thermal stability and chemical resistance.
And because of the high melting point, the thermal resistance to nylon 6 has abrasion resistance, high strength and stability. In the manufacture of car parts, airbags, garments, carpets, cd’s, gears, bearings, electrical insulation and so on. High water absorption and low chemical resistance are the disadvantages of this polyamide grade. Polyamide products 6.6 are used as injection molding for the manufacture of pipes, profiles, hoses, and automatic machines. to increase the hardness, thermal and thermal resistance and … this polyamide can be used in glass fiber.
The feature of polyamides or nylons
The degree of crystallinity has a significant impact on the range of melting of crystals and the absorption of moisture by polyamides. Increasing the percentage of crystallite increases chemical resistance against acid and open, strength and abrasion resistance, the amount of stress in the substrate, the increase in the melting temperature and the applied temperature range, and vice versa, reduces the isolation property, time, dielectric coefficient, transparency (matte Becoming) and the tendency to absorb moisture (due to the reduction of vacant spaces in amid chains).
Nylon absorbs more moisture than other polymers. Moisture has a significant impact on physical properties and dimensional stability.
Mostly nylon reinforcement on its base resin with glass fiber or carbon improves tensile and flexural strength, which is comparable to some cast alloys. Adding carbon fiber to nylon 6.6 will increase the tensile strength and increase the bending force. This agent also improves thermal, electrical and abrasion resistance.
Polyamides usually identifie with a number that represents the number of carbon atoms in the primary amino acids (nylon 6), or the number of carbon atoms in the diamino and dioxide (nylon 6.6).
