Polypropylene is a light-duty, easy to clean, webbing used in various applications including dog collars and leashes, luggage, health-related products, sporting goods, tote bags, and many others. Polypropylene webbing repels water, is mildew resistant, and low stretch.
Polypropylene is much weaker, has a lower melting point, and is less resistant to abrasion than its nylon and polyester counterparts. However, it is much lighter and will absorb the least amount of water weight. It is a good choice for backpack straps, tarp tie-outs, and wider tree straps. With a tree strap wider than one inch, polypropylene becomes a good choice because it is so low in weight and stretch.
As a thermoplastic polymer or synthetic resin, polypropylene is a type of manufactured, or man-made, fabric.
One of the most valuable features of polypropylene resin is that it is highly heat resistant, colorfast, and waterproof. The polymers are incredibly lightweight, allowing many items, such as ropes, to float on top of the water.
While the varieties of polypropylene vary in thickness and strength, all types are mold, mildew, moisture and rot resistant, making them excellent choices for outdoor applications.
Polypropylene webbing is a lightweight, easy-to-clean material that is used in a variety of applications such as dog collars and leashes, luggage, health-related devices, sporting goods, tote bags, and more.
Nylon and polypropylene are both durable and stress-resistant, but polypropylene is sturdier. Polypropylene is also electrically robust due to its excellent moisture resistance.
