Nylon

Polyester

Chemical Name

Polyamide

Polyethylene Naphthalate

Manufacture

Created as a liquid, mechanically spun and dried into individual fibers

Spun into thread from a chemical solution

Materials

Polyamide is made from petroleum

Polymer production from coal, air, water, and petroleum products

Environmental Impact

Often made from unavoidable oil refinery byproducts

Non-biodegradable but can be recycled, including 100% recycled options

Flammable

Yes: Melts then burns rapidly

Yes: Melts and burns at the same time

Maintenance

Pros of Polyamide (Nylon)

8-10% Stretch at Rated Capacity: Nylon slings offer a stretch at rated capacity, which can assist in reducing shock loading, particularly beneficial in certain lifting scenarios, (however this can also be a negative as it can affect the load's balance, especially if moving irregularly shaped loads).

 

Unaffected by Grease and Oil: Nylon slings remain resilient in the presence of grease and oil, ensuring reliability in industrial environments where these substances are common.

 

Resistant to Aldehydes, Ethers, and Strong Alkalis: Nylon slings exhibit resistance to a range of chemicals, including aldehydes, ethers, and strong alkalis, expanding their versatility.

Cons of Polyamide (Nylon):

Not Recommended for Acidic Environments or Bleaching Agents: Unsuitable for use in acidic environments or with bleaching agents, necessitating careful consideration in chemical applications.

 

Moisture Retention: Retain moisture, potentially leading to added stretch under load, an aspect to account for in wet conditions.

 

Conductivity: Nylon slings can conduct electricity when exposed to moisture or water, highlighting the importance of safety precautions.

 

Degradation with UV Light: Susceptible to degradation when exposed to UV light, requiring protection from sunlight to maintain their integrity.

 

Rising Production Costs: Nylon production costs are on the rise, potentially leading to higher prices for the end consumer.

Pros of Polyethylene Naphtholate (Polyester)

pOLYESTER WEB SLING

Approximately 3% Stretch at Rated Capacity: Polyester slings offer about 3% stretch at rated capacity, resulting in less bounce during lifts, which enhances load control.

 

Soft and Less Abrasive: Polyester is a softer material that is less abrasive, making it suitable for sensitive or delicate finishes on loads.

 

Lower Liquid Absorption: Exhibits lower liquid absorption compared to nylon and is non-conductive, ensuring material integrity in various conditions.

 

Resistant to Acids and Bleaching Agents: Resistant to acidic environments and interactions with bleaching agents, expanding their applicability.

 

Suitable for Low-Headroom Lifts: Polyester slings are suitable for low-headroom lifts, offering flexibility in lifting operations.

 

Cost-Effective: Generally more cost-effective in terms of material costings and production, providing a budget-friendly option.

Cons of Polyethylene Naphtholate (Polyester)

Not Recommended for Alkaline Environments: Polyester slings are not recommended for use in alkaline environments, including exposure to aldehydes, ethers, and strong alkalis.

Final Thoughts

In conclusion, when it comes to choosing between Nylon and Polyester for industrial applications, Polyester emerges as the preferred option. Its qualities, such as lower liquid absorption, resistance to acids, and bleaching agents, and cost-effectiveness, make it a reliable choice for various lifting scenarios. While Nylon offers its advantages, Polyester's attributes align better with the needs of industrial environments
