Polyvinyl Chloride (PVC)

Polyvinyl Chloride or PVC is the modern day material that is used to make most Christmas Trees. PVC is a cheap material to make consisting of a lot of vinyl chloride molecules linked together to form polymer. PVC comes in the form of white power but is compounded into a solid. To make the substance more flexible, they add phthalates. They also add to it, Bisphenol A (BPA) and chloride. PVC is made to use pipes, pipe fittings, pipe conduits, vinyl flooring, and vinyl siding. It is used to make wire and cable coatings, packaging materials, wrapping film, gutters, downspouts, door and window frames, gaskets, electrical insulation, hoses, sealant liners, paper and textile finishes, thin sheeting, roof membranes, swimming pool liners, weatherstripping, flashing, molding, irrigation systems, containers, and automotive parts, tops, and floor mats. PVC does not come from nature, instead to make all of those things they have to take ingredients from nature to make it. When phthalates is added to PVC it can be used to make medical devices such as blood bags, blood and respiratory tubing, feeding tubes, catheters, parts of dialysis devices, and heart bypass tubing. Phthalates are used in PVC plastics such as garden hoses, inflatable recreational toys, and other toys. Consumer products made with PVC include raincoats, toys, shoe soles, shades and blinds, seat covers, shower curtains, furniture, carpet backing, plastic bags, and credit cards.
