The influence of adverse pool water chemistry on the. vinyl was assessed through observation of changes in vinyl. colour, weight, dimensions, tensile strength and elongation. (stretching). The laboratory studies revealed that the factors most. affecting vinyl liners are high chlorine concentration, and.
Vinyl Liners are placed inside the formed shape of a pool. Made of a heavy-gauge vinyl, they are used to contain the water within the inner surfaces of the walls and bottom. Vinyl liners are chemically inert, and enable the use of various materials as pool walls. Vinyl liners are used in virtually all above-ground pools and most non-masonry, in-ground pools. Vinyl swimming pool liners are protected against chemical degradation and UV fading. They also are extremely cold-resistant and crack-proof. Vinyl liners create a water-tight seal, preventing water loss. Vinyl liners have strong, double-welded seams stand up to winter's worst weather conditions.
