Manufactured Fibre Technology pp Cite as. Nylon 66 and nylon 6 are two important members of a group of polymers known as polyamides.

The differences between nylon 6 and nylon 6/6

The answer is in the numbers, which signify the type and quantity of polymer chains in their chemical structure. Nylon 6 is derived from one monomer, which is a molecule that can be bonded to other identical molecules to form polymers. For nylon 6, the monomer has six carbon atoms, hence the name nylon 6. However, they do share many of the same characteristics:. Nylons are not UV resistant, although you can add stabilisers to give them almost any effect you desire. Nylon 6, for example, absorbs UV light in its amide bonds. Polymers that lack pi electrons, such as polyethylene, can stand up better to UV rays.

Nanodiamond ND , an emerging new carbon material, was exploited to reinforce nylon 6,6 PA66 polymer composites. Surface modified nanodiamonds with acyl chloride end groups were employed to chemically graft into PA66, enhancing the interfacial adhesion and thus the mechanical properties.

Nylon 6 and nylon 66 fibres

Tensile, hardness, and impact tests were carried out for mechanical properties, while wear tests on pin-on-disc were carried out for tribological properties identification. Abrasion resistance tests were carried out on the TABER apparatus to analyze the abrasive wear of materials. Experimental results show that the mechanical properties and tribological behavior of nylon 6 got enhanced by the h-BN fillers. Tensile strength and modulus of elasticity were enhanced by Thermal stability was slightly increased, and crystallinity was little affected by the h-BN fillers. Nylon is used in many industrial applications and there are many subtypes of nylons available in the market. Nylon 6 is one of the well-known members of nylon family, having pleasant properties to be used in any mechanical assembly or component manufacturing.

Nylon 6 and nylon 66 are polyamide compounds. A polyamide is a polymer composed of repeating amide linkages -CO-NH- that are either synthetic or natural. Nylon 6 and nylon 66 are synthetic polyamides. Nylon 6 is a semi-crystalline polyamide and is not a condensation polymer. Nylon 66 is another form of polyamide. The main difference between nylon 6 and nylon 66 is that nylon 6 is formed via ring opening polymerization whereas nylon 66 is formed via condensation polymerization.

Difference Between Nylon 6 and Nylon 66

At the molecular level, nylon contains hydrophilic amide groups. Therefore nylon is water-absorbent. Water absorption will result in dimensional change. The water-absorption rates shown in Table 36 represent values based on immersion in water and therefore differ from atmospheric equilibrium water absorption. Figure 34 shows the change over time of water-absorption rates for each type of nylon.

It, and nylon 6 , are the two most common for textile and plastic industries. Nylon 66 is made of two monomers each containing 6 carbon atoms, hexamethylenediamine and adipic acid , which give nylon 66 its name. Nylon -6,6 is synthesized by polycondensation of hexamethylenediamine and adipic acid. Equivalent amounts of hexamethylenediamine and adipic acid are combined with water in a reactor.

Nylon 6 and Nylon 66 are two of the most popular polymers used in the plastics, automotive and textile industries. As the similarity between their names suggests, the two share some properties, but there are also key differences between these two types of nylon. An exploration of the different chemical structures of the two materials can help you understand which jobs are best performed by Nylon 6 and which are better handled by Nylon Though both are known for their lightweight durability, the difference in chemical structures between Nylon 6 and Nylon 66 make Nylon 66 better suited for high-performing industrial products, whereas Nylon 6 is used in items that need more flexibility and luster. Both Nylon 6 and Nylon 66 are polyamides, which means they are molecules whose repeating units are linked by amide bonds.

NYLON 6/10 (PA) — POLYAMIDE 6/10

The reason for the differences is largely due to their differences in chemical structure. Nylon 6 is made from one monomer which has 6 carbon atoms whilst Nylon 66 is made from 2 monomers with each one having 6 carbon atoms, hence the Nylon 66 name. Other key differences between the two nylons are water absorption rates and heat deflection temperatures. As Nylon 6 absorbs more water than Nylon 66 and has lower heat deflection temperatures, it is not suited to applications that are exposed to water at high temperatures. Nylon 66 would be a better choice between the two.
