Understanding TPU: The Technology Inside Waterproof Blankets

Posted on August 03 2023

In the world of waterproof blankets, advancements have played a significant role in revolutionizing the way we experience comfort and protection during outdoor adventures and indoor activities. Among these innovations, TPU (Thermoplastic Polyurethane) stands out as a remarkable material that has redefined waterproofing capabilities. In this article, we will explore the fascinating world of TPU, its unique properties, and how it is used in creating top-of-the-line waterproof blankets, ensuring any experience is truly remarkable.

The Magic of TPU 

TPU, short for Thermoplastic Polyurethane, is a versatile and high-performance material that has gained popularity for its exceptional properties. It is a type of polyurethane plastic that offers a unique combination of elasticity, transparency, and resistance to oil, grease, abrasion, and chemicals. These qualities make TPU an ideal candidate for applications requiring flexibility, durability, and water resistance. When placed as a layer inside of a waterproof blanket comfort can utility can perfectly intertwine. Have no fear, TPU is safe, it is a non-toxic and food safe material.

Key Properties of TPU

  • Flexibility and Elasticity: One of the most significant advantages of TPU is its excellent flexibility and elasticity. It can be easily molded into various shapes and maintains its original form after repeated stretching, bending, or compression. This resilience allows TPU to endure the demands of outdoor use without compromising its integrity.

  • Water Resistance: TPU boasts remarkable water-resistant properties, making it an ideal material for waterproofing applications. Its molecular structure creates a barrier that repels water, preventing it from permeating the fabric. This essential characteristic makes TPU a preferred choice for waterproof blankets.

  • Abrasion and Tear Resistance: TPU exhibits impressive resistance to abrasion and tearing, ensuring the longevity of products made from this material. Whether used in outdoor gear, footwear, or waterproof blankets, TPU's ability to withstand wear and tear adds to its durability.

How TPU is Used in Waterproof Blankets

The integration of TPU into waterproof blankets is a game-changer, elevating their functionality and performance. Here's how TPU is utilized to create top-quality waterproof blankets:

  • TPU Layers: In the manufacturing process, a layer of TPU is applied as a coating to the inner or middle fabric of the blanket. This TPU coating forms a water-resistant barrier, preventing moisture from penetrating the fabric and reaching the two external layers. The result is a semi absorbable surface with a waterproof inner liner (or membrane) that protects the user and the blanket from dampness, spills, and moisture.

  • Sealing Seams: In the construction of waterproof blankets, seams are critical areas that are prone to water infiltration. TPU tapes or films can be used to seal these seams, preventing water from seeping through the stitching. This technique ensures that the entire blanket remains fully water-resistant, providing reliable protection during outdoor activities.

Advantages of TPU in Waterproof Blankets

  • Enhanced Waterproofing: TPU's remarkable water-resistant properties provide waterproof blankets with reliable protection against dampness, spills, and moisture. This ensures a dry and comfortable experience during outdoor adventures or intimate moments.

  • Flexibility and Comfort: The flexibility and elasticity of TPU contribute to the overall comfort of the waterproof blanket. It allows the blanket to conform to the body's contours, providing a snug and cozy feeling for users.

  • Durability and Longevity: TPU's resistance to abrasion and tearing enhances the durability and longevity of waterproof blankets. This ensures that the blanket remains in top condition, even after prolonged use in challenging outdoor conditions.
