• Polyvinylchloride (PVH) is the plastic polymer used for production of the widest row of production - from pipelines to windows. PVH consists of chloride of the vinyl integrated with plastic materials. Such combination creates polymer which then is filled in in templates. As polymer stiffens, it gets durability. For production of PVH producers mix raw materials with various additives, its useful properties giving to material.
Advantages of material
• Advantages of PVH depends on advantages of chemical additives in raw materials. For example, producers of PVC windows often use the special chemical ingredients developed for resistance of corrosion and to severe weather conditions. Windows from such material receive a surface, impenetrable for rainy weather. PVH also resists to ultra-violet radiation. Producers also declare additional characteristics of material, such as high warm and sound insulation, and also easy secondary processing of PVH.
Durability and flexibility
• Polyvinylchloride has relative durability to mechanical damages, however if you, for example, strike it with the hammer, you can damage it. Material also possesses resistance to a scratching and is rather flexible. Flexibility of material allows to apply it in limited space that does PVC to lungs in work. However this flexibility can also become a shortcoming as does material rather weak and incapable to maintain high loadings as, for example, a tree. PVC easily washes that does it by fine material for house owners.
• Producers of PVC, and also the companies which are engaged in PVC production sale offer a huge number of information extolling qualities of material. For example, many producers call PVC fire-resistant or refractory. However, according to Ulrich Naak, the author of the book "Facades: the principles of designing", material shows low fire resistance. While some producers speak about secondary processing of PVC, Kallun Hill, the author of the book "Transformation of a Tree", writes that you, in principle, can reuse PVC from old windows for new, but attempt to get rid of material can do harm to environment.
