When choosing a coated webbing for your product, two of the most common options are TPU (thermoplastic polyurethane) and PVC (polyvinyl chloride). Both materials offer a waterproof, easy-to-clean surface over a strong fabric core, but they differ significantly in performance, cost, and environmental impact.

Biothane is a well-known name in the world of pet gear, outdoor equipment, and industrial strapping. It has gained a reputation for being tough, waterproof, and easy to clean. But what exactly is Biothane made of, and what gives it such desirable properties?

To understand PVC coated webbing, we first need to look at its core material: PVC, or polyvinyl chloride. PVC is one of the most widely used synthetic polymers in the world. In its raw form, it is naturally rigid, but by adding plasticizers, it can be made soft and flexible.

To understand TPU coated webbing, we first need to look at the material itself. TPU, or thermoplastic polyurethane, is a high-performance elastomer that combines the best properties of rubber and plastic. It is known for its exceptional flexibility, abrasion resistance, and transparency.

Simply put, it is a composite material consisting of a strong fabric core—typically made from polyester or nylon—that is encapsulated or coated with a layer of polymer. This coating is applied through a high-temperature extrusion or similar process, creating a seamless, protective outer layer that dramatically enhances the webbing’s properties while retaining the strength of the inner fabric.

When selecting a collar and leash for your pet, getting the size right directly affects wearing comfort and safety. The width of the coated webbing determines the load-bearing area and visual proportion, while the thickness influences the webbing's stiffness, feel, and tensile strength.
