Nylon is a strong, stiff engineering plastic with excellent bearing and wear properties. It is frequently used to replace metal bearings and bushings, often eliminating the need for external lubrication. Nylon is also used in medical instruments, plumbing systems, and sprinkler systems. It is extremely durable, which makes it good for barns, livestock, and watering systems. However, nylon has a low impact strength compared to other plastics, and it is not good for exposure to sunlight. On the other hand, plastic is a versatile material used in a wide range of applications, from construction to automotive. Plastic is known for its easy availability and economical price. One type of plastic, PVC, is popular in irrigation applications since it is not affected by ultraviolet rays and has great chemical resistance.

PVC is the most popular in irrigation applications
Nylon is a high-performance plastic material made from a synthetic polymer. It is significantly harder and stronger than ABS plastic and PVC. It is also more elastic than many other types of plastics. However, it is not as tough against forceful impacts as some other materials. For instance, nylon fittings will stretch in diameter and this could loosen the clamp.
In addition, nylon behaves differently from many other plastics in that it can absorb moisture from its surroundings, leading to dimensional changes and a loss in mechanical properties. This hygroscopicity may affect the performance of the material in conditions with high humidity or where precise tolerances must be maintained.
PVC, on the other hand, is the most popular in irrigation applications. This is because it has a very wide range of fittings and is not affected by ultraviolet rays. It also has great chemical resistance and there are some chemicals that PVC can handle that other materials like poly cannot. PVC is also very tough and is used in irrigation systems where lines are not below the frost level.
PVC is divided into two categories: class and schedule. The schedule system is the most common and the number that follows it designates the thickness of the walls. For instance, Schedule 40 pipe comes with a thickness of .133.
PVC is also used for most water distribution systems, including waste, irrigation, and drinking. This is because it neither releases nor absorbs toxic chemicals. However, it should not be burnt as the smoke is hazardous.

Nylon is not good for exposure to sunlight
Nylon is a highly versatile material with a wide range of applications, from clothing and commercial goods to industrial parts and products. It is a semi-crystalline thermoplastic that is commonly used in manufacturing due to its durability, flexibility, and toughness. However, nylon is not suitable for exposure to sunlight.
Nylon is susceptible to degradation when exposed to UV radiation, which is present in sunlight. UV radiation creates free radicals that break down the intermolecular bonds in nylon, leading to a loss of mechanical strength and impact resistance. This degradation process can cause nylon parts to weaken, become brittle, and crack or disintegrate over time. Even with additives to improve UV resistance, nylon will still degrade relatively quickly when exposed to sunlight for prolonged periods.
The sensitivity of nylon to UV radiation varies depending on the specific type of nylon. For example, nylon 6 is more resistant to UV rays than nylon 6/6, while nylon 12 offers even greater UV resistance. These variations in UV resistance are important to consider when selecting nylon for a project that will be exposed to sunlight, as the mechanical strength, temperature resistance, abrasion resistance, and water resistance of the material can be affected.
When designing products for outdoor use or applications with moderate to continuous exposure to UV radiation, it is crucial to choose a material with adequate UV resistance. While nylon may be suitable for some applications, its degradation when exposed to sunlight can impact its performance and longevity. Therefore, other UV-resistant plastics or materials may be more appropriate for specific projects requiring prolonged sun exposure.
In summary, while nylon has many advantageous properties, it is not the best choice for exposure to sunlight due to its susceptibility to UV degradation. This degradation can lead to negative effects on the material's mechanical properties and overall performance, making it unsuitable for outdoor use or applications with significant UV exposure. When considering nylon for a project, it is essential to keep in mind its limitations regarding UV resistance to ensure the material selection aligns with the specific requirements of the application.
