The phrase "low moisture transmission and high barrier performance" encapsulates the core performance characteristics of TPU protective films. Unlike conventional high-moisture-permeability films, this product features a controllable low-moisture transmission design, ensuring that excessive breathability does not compromise its protective capabilities. Its dense polymer structure establishes a high-strength barrier layer, effectively resisting liquid splashes and medium penetration, making it a critical functional barrier layer in industrial protective fabrics.
In mainstream composite fabric manufacturing processes, TPU film typically serves as the intermediate functional layer, combined with an outer wear-resistant fabric and an inner skin-friendly fabric to form a stable three-layer composite structure. The outer fabric provides wear and tear resistance, the middle film acts as an impermeable barrier, and the inner fabric offers softness and close fit, enabling the entire protective fabric system to exhibit multiple advantages-including resistance to aging, low-temperature performance, flexibility and damage resistance, as well as impermeability and chemical resistance.
