Understanding the Relative and Absolute Tensile Strengths of Different Netting Materials

Tensile strength can be a very important factor to consider when selecting netting materials for various applications. The ability of a netting material to withstand tension and stress is crucial to ensure its effectiveness and durability. This is particularly true where the netting will be subjected to frequent or periodic stress and tension. Different netting materials have varying tensile strengths, with some being stronger than others. 

Nylon type 6 and Nylon type 6,6 are popular netting materials known for their high tensile strength. Nylon type 6 has a tensile strength of approximately 10,000 PSI, while Nylon type 6,6 has a tensile strength of around 12,000 PSI. Both materials are durable, resistant to abrasions, and have good elasticity. These properties make them ideal for applications such as sports netting, safety barrier netting, and fishing nets.

Polyethylene is another common netting material known for its versatility and low cost. It has a tensile strength of approximately 3,000 PSI, which is significantly lower than that of Nylon type 6 and only about a quarter of the tensile strength of Nylon type 6,6. Despite this, polyethylene is still a popular choice for many applications such as agriculture, gardening, and fencing.

Kevlar is a high-performance netting material that is commonly used in applications where strength, light weight, and durability are critical. It has a tensile strength of approximately 500,000 PSI, making it one of the strongest netting materials available. Kevlar is often used in applications such as military gear, bulletproof vests, and aerospace engineering. It is also used commonly in the production of netting barrier netting where spectators require protection while enjoying a high level of event visibility. The combination of the light weight and inherent tensile strength of the Kevlar fiber allow barrier nets to be made from small diameter twine, maximizing visibility and optimizing the spectator experience.

High molecular weight polyethylene (HMWP) is another strong netting material with a tensile strength of approximately 6,000 PSI. It is often used in applications such as fishing nets, cargo nets, and barrier nets.

When selecting a netting material, it is important to consider the specific application and the required tensile strength. Factors such as environmental conditions, load capacity, and exposure to UV rays can also affect the durability of netting materials. In addition to tensile strength, other properties such as abrasion resistance, flexibility, and UV resistance should also be considered.  Ultimately, the specific application will govern the tensile strength requirement and the ultimate selection of fiber for your netting needs.

In conclusion, the tensile strength of netting materials varies widely and should be a key consideration when selecting the right material for a specific application. Nylon type 6, Nylon type 6,6, Polyethylene, Kevlar, and HMWP are just a few examples of netting materials with varying tensile strengths. Proper selection and understanding of netting materials can ensure the effectiveness and durability of netting applications.

Upshot: Knotted Nylon Netting Advantage

Speaking generally, the traditional workhorse of netting continues to be knotted nylon netting, which can be customized to accommodate a wide variety of twine and mesh sizes.  Knotted nylon netting – using either twisted nylon twine or braided nylon twine continues to be the go-to for most traditional applications which require a combination of high tensile strength and durability.  Type 6,6 nylon netting, as shown above, delivers a 20% increase in tensile strength vs the traditional Type 6 nylon.
