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 ).
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]
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.
It has a very low moisture absorption. The mixture of polyvinyl chloride and polyurea has a good bond strength. Closed-cell PVC foam takes solid shape due to its linear structure. However, due to this structure, it is more brittle than open-celled PVC foam.
Plastisol. A plastisol is a colloidal dispersion of small polymer particles, usually polyvinyl chloride (PVC), in a liquid plasticizer.When heated to around 180 °C (356 °F), the plastic particles absorb the plasticizer, causing them to swell and fuse together forming a viscous gel.
Currently, the toys-for-adults market is worth £1bn in the UK, while £1 of every £3 currently spent on toys is spent by a “kidult” – an adult consumer interested in entertainment aimed at ...
Toy safety is the practice of ensuring that toys, especially those made for children, are safe, usually through the application of set safety standards. In many countries, commercial toys must be able to pass safety tests in order to be sold.
