Widely used in construction for pipes, fittings, and cable insulation due to its durability, chemical resistance, and low cost. Common in plumbing systems because it resists corrosion and scaling. Employed in window profiles and siding for its insulating properties and ability to withstand weathering. Used in healthcare for blood bags and tubing, though plasticizers are added for flexibility. Found in wire and cable coatings for electrical insulation. Also used in flooring, roofing membranes, and inflatable products. Its flame retardant properties make it suitable for applications requiring reduced fire risk.
