Durable PVC Folding Pool Cover for Irregular Shapes | Water Crown

Durable PVC folding pool covers leverage polyvinyl chloride’s versatility to balance strength, flexibility, and weather resistance. These covers feature multi layered PVC composites, typically consisting of: Top Layer: UV stabilized PVC film with anti oxidant additives to prevent degradation from sunlight, rated for 1000+ hours of UV exposure without significant brittleness. Reinforcement Layer: Woven polyester or fiberglass mesh embedded within the PVC to enhance tensile strength, often achieving breaking strengths of 3000+ Newtons per meter. Waterproof Membrane: A dense PVC inner layer that blocks water penetration, tested to withstand hydrostatic pressures equivalent to 6 inches (15cm) of standing water. Bottom Layer: Anti slip or anti abrasion coating to protect the cover from pool deck friction during folding/unfolding. Manufacturing processes like calendering or extrusion ensure uniform thickness (typically 0.8 1.2mm) and consistent material properties. PVC covers resist chemical degradation from pool chemicals (chlorine, bromine) and exhibit low water absorption, reducing weight when wet. Their flexibility allows easy folding around hinges or tracks, while reinforced edges with webbing or metal grommets enhance anchoring stability. Suitable for both above ground and inground pools, these covers offer a cost effective solution with typical lifespans of 5 8 years with proper maintenance.
