Read： 951 Time：20months ago Source：Transform the World with Simplicity

Nylon is a synthetic fiber, also known as polyamide (PA) fiber, which has important properties and uses in the field of chemical production raw materials. The following is a detailed introduction about the nature and use of nylon.

1. the properties of nylon

1. physical properties
nylon has high strength, high toughness, wear resistance, chemical corrosion resistance and other excellent physical properties. Its strength is higher than most natural fibers and synthetic fibers, so it is often used to make textiles, ropes, filters, etc. that require higher strength and durability.

2. chemical properties
nylon has good acid and alkali resistance, can be used in acidic or alkaline environment, but not strong acid and alkali resistance. In addition, nylon also has good oil resistance and can be used in some oily environments.

3. thermal properties of
nylon melting point is higher, generally between 210-260 ℃, with good thermal stability. However, long-term use at high temperatures will cause aging and discoloration of nylon.

2. nylon use

1. textile
nylon is widely used in the field of textiles, such as the production of sportswear, outdoor clothing, swimwear, socks and so on. This is because nylon has excellent physical properties, which can improve the strength, toughness, wear resistance and chemical resistance of textiles.

2. Rope and filter
Because of the high strength and wear resistance of nylon, it is often used to make rope and filter products.

3. engineering plastics
nylon can also be used as engineering plastics, such as the production of auto parts, electrical parts, etc. This is because nylon has good heat resistance, oil resistance and chemical resistance.

4. Other fields
In addition to the above fields, nylon is also widely used in packaging, printing, chemical and other fields.

In short, nylon as an important chemical production raw materials, has a wide range of uses and excellent properties. In the future development, with the continuous progress of science and technology and the continuous expansion of application fields, the use and performance of nylon will be further improved and improved.
