Biothane straps are made from a proprietary composite material that combines a flexible, durable polymer core with a waterproof, easily cleanable TPU (thermoplastic polyurethane) or PVC (polyvinyl chloride) coating. This coating is bonded to a strong, flexible polyester or nylon fabric base, giving the straps their characteristic strength, flexibility, and resistance to water, dirt, and abrasion.

Biothane is known for being a low-maintenance, hygienic alternative to traditional leather, and it is commonly used for dog leashes, horse tack, belts, and other applications requiring durability and ease of cleaning. The material is also available in various colors and finishes, making it both functional and customizable.
