The FR Waterproof Closed-End Zipper is a specialized, high-performance fastener designed for flame-resistant (FR) workwear in hazardous industries such as oil & gas, utilities, and firefighting. It features Nomex® aramid tape for inherent flame retardancy—self-extinguishing without melting or dripping—paired with a TPU/PU laminated coating for full waterproof sealing when closed. The closed-end configuration provides secure, non-separating closure with excellent durability, making it ideal for jackets, coveralls, and rain gear while meeting strict safety standards like NFPA 2112.
