Some familiar household synthetic polymers include: Nylons in textiles and fabrics, Teflon in non-stick pans, Bakelite for electrical switches, polyvinyl chloride (PVC) in pipes, etc. The common PET bottles are made of a synthetic polymer, polyethylene terephthalate.
Polyvinyl chloride is formed in flat sheets in a variety of thicknesses and colors. As flat sheets, PVC is often expanded to create voids in the interior of the material, providing additional thickness without additional weight and minimal extra cost (see closed-cell PVC foamboard ).
Vinyl chloride is an organochloride with the formula H 2 C=CHCl. It is also called vinyl chloride monomer (VCM) or chloroethene. It is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride (PVC). Vinyl chloride is a colourless flammable gas that has a sweet odor and is carcinogenic.
Vinyl polymers are subject of several structural variations, which greatly expands the range of polymers and their applications. With the exception of polyethylene, vinyl polymers can arise from head-to-tail linking of monomers, head-to-head combined with tail-to-tail, or a mixture of those two patterns. Additionally the substituted carbon center in such polymers is stereogenic (a "chiral center")
Guarantees the sale of electronic products free of phthalates. [74] July 4, 2017: Included in the candidate list referred to as substances toxic for reproduction. [75] November 23, 2021: DIBP is declared as an endocrine disrupting chemical. [76] August 11, 2021: The European Parliament eliminates DIBP and other phthalates from sanitary products ...
Vinyon is a synthetic fiber made from polyvinyl chloride. In some countries other than the United States, vinyon fibers are referred to as polyvinyl chloride fibers. It can bind non-woven fibers and fabrics. It was invented in 1939. It has the same health problems associated with chlorinated polymers.
For example, CR detected phthalates—a chemical used to make plastic more flexible and durable—in almost all of the foods it assessed. "High levels" of the chemical were present in many of ...
IPK is an acrylic-polyvinyl chloride composite engineered for thermoforming applications, combining properties of both acrylic and polyvinyl chloride plastics. Acrylic adds rigidity and formability, while polyvinyl chloride, more commonly known as PVC, adds toughness and chemical resistance. Standard sheet thickness is .080 and IPK Acrylic ...
