What is BioThane and is every waterproof belt made from it?

BioThane is a brand name for coated webbing from BioThane Coated Webbing Corp. The core consists of polyester and has a layer of TPU or PVC. This makes the material waterproof and easy to clean. Not every coated or waterproof dog leash is automatically from BioThane. The manufacturer must explicitly confirm the brand and material.

What is BioThane made of?

The polyester core gives the tire its tensile strength. The coating protects the outside and provides a smooth, easily removable surface. BioThane is therefore not a general material name such as nylon or polyester, but a registered brand name.

The manufacturer uses different coatings and types of tape. Properties may therefore differ per version. When purchasing a dog leash, always ask for the complete product, not just for one well-known material name.

Why is it used for dog leashes?

Coated webbing is practical when a leash often gets wet or dirty. Water and mud are usually easy to wipe away and the surface absorbs dirt less quickly than untreated textiles.

That does not mean that every part is maintenance-free. A dog leash also consists of hooks, rings, connections and sometimes stitching. These parts together determine how the belt should be used and cared for.

BioThane and other materials compared

Material Typical feeling Maintenance Please note
BioThane Smooth and coated Wipe often with water Check type of coating and fittings
Coated strap without brand confirmation Varies per product Follow brand instructions Don't automatically call it BioThane
Polyester rope Soft and flexible Hand wash and dry thoroughly Can absorb water
Nylon strap Light and flexible Varies by finish Uncoated nylon is not waterproof by itself

Is the UNBORINGBYPIP dog leash made of BioThane?

That has not been confirmed in the product fact sheet at this time. The waterproof dog leash is 100 percent waterproof, but that property alone does not prove that the material is BioThane. That is why we do not call the material that until the supplier or product specification confirms this.

If you especially want a leash that is easy to clean, take a look at the waterproof dog leashes. Also read how to clean a waterproof dog leash and what to pay attention to with a strong dog leash.

How to check a material claim

  1. Find the exact material name in the product specifications.
  2. Check if BioThane is mentioned as a brand.
  3. If in doubt, ask for confirmation from the brand or supplier.
  4. Also view bandwidth, usage and connections.
  5. Follow the care instructions of the final product.

What not to do

Do not use BioThane as a collective name for every waterproof tire. That is factually incorrect and makes comparison more difficult. Also, do not assume strength based on the coating. The manufacturer explains that the polyester core provides the tensile strength.

Do not call a product odor-free or indestructible without a concrete, substantiated product specification. Easy cleaning is not the same as never requiring maintenance.

Frequently asked questions

Is BioThane the same as plastic?

BioThane consists of a polyester belt with a TPU or PVC coating. So you are looking at a composite, coated tire and not solid plastic.

Is BioThane waterproof?

The official manufacturer describes BioThane as waterproof. Also check the connections and fittings of a finished product.

Is every waterproof dog leash from BioThane?

No. Other coated materials can also be waterproof. Only an explicit product specification confirms that it is BioThane.

Is BioThane stronger than nylon?

You cannot say that in general. Strength depends on the precise band, width, core, connections and fittings.

How do you clean BioThane?

Follow the instructions of the maker of the final product. Water and a mild cleaning agent are often sufficient, but fittings and connections may require extra attention.
