Makers of winch and ratchet straps for cargo control can choose from a number of different construction materials. The three most common are propylene, nylon, and polyester. Of those three, propylene is not recommended for the trucking industry because it does not handle heavy loads very well. Among the remaining two choices, the latter is the best choice for cargo control.
To say that all ratchet straps are not equal is obvious if you understand the differences between the three materials. Propylene is material generally reserved for needs that do not require heavy load limits. For example, you might find it used to make bag straps, belts, and other similar things. Winch and ratchet straps for flatbed trucking are rarely, if ever, made with propylene.
Five Reasons Nylon and Polyester Are Better
Before you buy new winch or ratchet straps for your truck, we encourage you to consider material choices. The material you choose could end up having a significant impact on how securely your cargo is carried. Below are five reasons nylon and polyester are far better choices than propylene.
1. UV Protection
Ultraviolet rays from the sun can do damage to cargo control products without a truck driver ever knowing it. Ultraviolet rays can dry out and crack rubber bungee straps; they cause significant discoloration of truck tarps; they can reduce the life of the stitching material used to hold tarp material together. Where ratchet straps are concerned, polyester is the most resistant to UV rays. Nylon is fairly resistant as well.
2. Overall Strength
The biggest reason propylene is inappropriate for heavy loads is because it stretches considerably. Stretching of up to 50% is not abnormal for propylene. Nylon can stretch up to 30% under the heaviest loads while polyester is not likely to stretch beyond 15%. Once again, that makes polyester ideal for ratchet straps.
3. Tensile Strength
Tensile strength is defined as the maximum load a material can bear before breaking. Once again, propylene does not hold up very well. The average propylene strap is good only for about 700 pounds whereas nylon and polyester can manage loads of up to 7,000 pounds and 10,000 pounds respectively.
4. Resistance to Abrasion
Abrasion is a big problem in the trucking industry. From the sharp edges of cargo to the flatbed trailers that carry it, there are a lot of things that can cause abrasive friction on ratchet straps. Neither propylene nor nylon stand up well to abrasion. Polyester does.
5. Water Resistance
Lastly, water resistance is something truckers have to be concerned about. If a strap that were to become saturated it would automatically be weaker under load. It would also be prone to mold growth and more rapid breakdown under continual cycles of saturation and drying.
Believe it or not, the worst performer in the water-resistant category is nylon. Propylene actually does better in this regard, which is why it is used for things like lifejacket straps. Ultimately though, polyester is again the clear winner.
