What is the difference between polypropylene safety rope and nylon safety rope?

There are significant differences between polypropylene safety rope and nylon safety rope in several aspects. Here is a detailed comparison of the two safety ropes:

First, material and raw materials

polypropylene safety rope: the raw material is synthetic fiber isotactic polypropylene fiber made of propylene, a by-product of petroleum refining.

Nylon safety rope: the raw material is polyamide fiber, which is often said to be nylon, which is widely used in various fields.

Second, performance characteristics

polypropylene safety rope:

High strength: Polypropylene is a high-strength fiber that is stronger than nylon rope for the same weight.

Light and soft: polypropylene rope is lighter in weight and more flexible, easy to carry and use.

Anti-corrosion and waterproof: It has good corrosion resistance in wet, water immersion and a variety of acid and alkali environments.

Poor heat resistance: poor thermal stability, easy aging, not resistant to ironing, the use temperature is generally -30~+140℃.

Nylon safety rope:

High strength, light weight: long-term use is not easy to fatigue.

Chemical resistance: No chemical reaction occurs in the case of oil, but the acid resistance is weak, such as sulfuric acid, nitric acid and hydrochloric acid can decompose nylon fibers without any visual reaction.

Good elasticity: nylon safety rope has greater elasticity and is suitable for occasions where a certain extension is needed to absorb the impact energy.

Hygroscopic: the weight will increase after entering the water, but the original strength will be restored after drying.

3. Application scenarios

polypropylene safety rope: Due to its high strength, lightweight and soft and anti-corrosion and waterproof characteristics, polypropylene safety rope is suitable for a variety of complex environments, such as wet, acid and alkali environment.

Nylon safety rope: Because of its excellent toughness, flexibility and elasticity, nylon safety rope is more suitable for climbing power ropes that need to absorb crash energy, as well as semi-static ropes in industrial aerial work, rope exploration and rescue fields.

4. Price and maintenance

Price: In general, the price of polypropylene safety rope and nylon safety rope is affected by a variety of factors, such as raw material cost, production process and so on. Therefore, it is impossible to generalize about which is cheaper.

Maintenance: Both require regular inspection for wear and damage, and timely replacement of damaged ropes. At the same time, care should be taken to avoid aging or damage caused by overuse and improper storage.

In summary, there are significant differences between polypropylene safety rope and nylon safety rope in terms of material, performance characteristics and application scenarios. In the selection, should be based on the specific use of the environment and needs for comprehensive consideration.
