The most common ingredient for vinyl fence is polyvinyl chloride which is modified to provide superior strength and ultraviolet resistance by including impact modifiers and ultraviolet inhibitors. The formulation was originally derived from that used for vinyl windows which has had a history of durability and structural integrity.
PVC is durable and low maintenance, making it a popular choice for fencing. It is also non-toxic and safe for use in residential and commercial settings. The PVC is mixed with other ingredients to give it strength and UV resistance, and it is then molded into the desired shape and size. The final product is a fence that is strong, weather-resistant, and long-lasting.
