SEA VISION 350 screen fabrics are manufactured with a "high tenacity" polyester core yarn, then coated with lead-free PVC. This combination of high-tenacity polyester with PVC offers a highly performing fabric which remains totally stable when exposed to changes in the environment. SEA VISION 350 fabrics are flame retardant and antibacterial. They also are highly resistant to tearing and fraying and are resistant to exposures encountered in a maritime environment.
