TPU waterproof zippers have emerged as a popular waterproof accessory in outdoor gear. When people think of zippers, their first associations are typically metal zippers or conventional nylon zippers; however, zippers made from thermoplastic polyurethane-known as TPU material-have recently seen a steady rise in popularity within the outdoor and apparel sectors.
What are the advantages of TPU zippers?
Excellent waterproof performance: The dense structure of TPU material, combined with the heat-pressing process, ensures a seamless fit that makes it difficult for water to penetrate; this property makes the material widely suitable for waterproof bags, diving suits, and other related products.
Soft and flexible: Compared to metal zippers, it is lighter in weight, feels softer to the touch, does not cause cold-induced stiffness in low-temperature environments, and resists deformation even after repeated bending.
Low-temperature resistance: Even in environments with temperatures as low as several tens of degrees below zero, it retains its toughness and does not become brittle or crack, making it ideal for polar gear and high-altitude trekking equipment.
Eco-friendly and recyclable: TPU is recyclable and reusable, offering superior environmental performance compared to conventional zipper materials, and making it easier to obtain eco-certifications.
Where is it most common?
It can be found in a wide range of products, from outdoor jackets and hiking backpacks to waterproof footwear, medical protective gear, and even baby products.
Summary: If you're looking for waterproof, lightweight, and durable gear, go for a TPU zipper-it's an excellent choice!
