A manufacturer's label may say, for example, 67% polyester, 33% polyurethane for a fabric that contains no PVC; or 80% polyvinyl chloride, 20% polyurethane with mention of the polyester backing omitted. PVC clothing is a highly resistant material and waterproof. [3]
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). Sheets are cut using saws and rotary cutting equipment.
The term "waterproof" refers to conformance to a governing specification [1] and specific conditions of a laboratory test method. They are usually natural or synthetic fabrics that are laminated or coated with a waterproofing material such as wax, rubber, polyvinyl chloride (PVC), polyurethane (PU), silicone elastomer, or fluoropolymers ...
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.
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 ("vinyl") tarpaulins are industrial-grade and intended for heavy-duty use. They are constructed of 10 oz/sq yd (340 g/m 2) coated yellow vinyl. This makes it waterproof and gives it a high abrasion resistance and tear strength. These resist oil, acid, grease and mildew. The vinyl tarp is ideal for agriculture, construction ...
Polyvinyl chloride (PVC) PVC is naturally clear. It has high resistance to oils and transmits very little oxygen. It provides a strong barrier to most gases, and its drop-impact resistance is also very good. This material is chemically resistant, but it is vulnerable to some solvents.
It can be made of many plastics but PVC (polyvinyl chloride, "vinyl") is the most popular, as it stretches well and gives effective and long-lasting insulation. Electrical tape for class H insulation is made of fiberglass cloth.
