In a fire, PVC can form hydrogen chloride fumes; the chlorine serves to scavenge free radicals, making PVC-coated wires fire retardant. While hydrogen chloride fumes can also pose a health hazard in their own right, it dissolves in moisture and breaks down onto surfaces, particularly in areas where the air is cool enough to breathe, so would ...
The plastic kits and covers are mostly made of synthetic polymers like polythene, and tires are manufactured from polybutadienes. [1] However, due to the environmental issues created by these synthetic polymers which are mostly non-biodegradable and often synthesized from petroleum, alternatives like bioplastics are also being considered. They ...
PVC plastic is often called "vinyl" and this type of clothing is commonly known as vinyl clothing. [2] PVC is sometimes confused with the similarly shiny patent leather. The terms "PVC", "vinyl" and "PU" tend to be used interchangeably by retailers for clothing made from shiny plastic-coated fabrics.
The cured grain can be machined like any PVC part. [3] PVC plastisol propellants were developed by the Atlantic Research Corporation and were widely used in the 1950s and 1960s in various solid rocket motors. Notable examples include the Arcas sounding rocket, the FIM-43 Redeye MANPADS and the sustainer motor of RIM-2 Terrier. [3]

PVC foamboard is distinct from the extra-lightweight foamcore board, laminated of foam and card surfaces, used for indoor signage and modelling. Like PVC, closed-cell PVC foamboard is solid and has a very rigid structure. Where it differs is in its closed-cell foam structure, which makes it very light (as little as half the weight of solid PVC ...
