Industrial Properties and Applications of PVC
Weather Proof.PVC is resistant to aggressive environmental factors and therefore is the most common polymer for the manufacture of roofing
Versatility.PVC can be both flexible and rigid
Ognezaschischennost.Polyvinyl chloride is one of the inflammable material due to the presence of chlorine in the molecule
Durability.PVC materials can serve up to 100 years or more
Hygiene.PVC - the most common polymer for the manufacture of medical products, including containers for the storage of blood and plasma.Polyvinyl chloride has a high calorific value, if disposed of in incinerators, a large amount of heat for heating of residential and industrial buildings, and it does not pollute the environment
Barrier.PVC has a very low permeability to liquids, vapors and gases
Sustainability.PVC contains only 43% of oil derivatives, thus saving non-renewable natural resources.
Possibility of recycling.
Cost.Production of PVC - one of the cheapest large polymers, providing many products for the best price-quality.
PVC is processed by all known methods of plastics processing:extrusion, injection molding, calendering, extrusion, rolling - and is one of the most common plastics.World production of PVC is 16.5% of the total output of plastics - in third place in the world table of ranks of polymeric materials.
range of products manufactured on the basis of PVC and its products - vinyl plastic and plastic, is extremely high.
PVC can be obtained by a wide range of films with different properties by varying the composition and the degree of orientation.Changes in the composition, mainly the introduction of a plasticizer, provides a film of hard, brittle to soft, sticky, extendable.By varying the degree of orientation, receive a film of equal strength to fully odnoosnoorientirovannyh biaxially-oriented.
Films of PVC stabilizers include thermal and thermo-oxidative degradation, anti-static additive to prevent clumping due to the accumulation of static electricity.Properties of plasticized polyvinyl chloride films depend on the nature and amount of plasticizer.In general, an increase of plasticizer content increases the transparency and softness of the film, improving cross properties at low temperatures.Plasticized and unplasticized PVC film are sealed by welding high.On both types of films can be applied without pre-printed surface treatment, in contrast to films of polypropylene and polyethylene.Thin films of plasticized PVC is widely used as shrink wrap and Stretch for trays and trays of food, such as fresh meat.They must provide high oxygen permeability to preserve fresh meat purple.Thick films of plasticized polyvinyl chloride used for the production of packaging for shampoo, lubricants.Resistant and easy formability of uPVC film and its copolymers are used for thermoforming of various products.A distinguishing feature of materials based on copolymers of polyvinylidene chloride and polivnnilhlorida (PVDC) is a very low vapor and gas permeability.PVDC film, often used as a shrink wrap film for poultry, ham, cheese.Evacuated bags PVDC is also used for cheese ripening.The use of PVDC in this case excludes dehydration and crust formation, allowing you to get more soft cheeses.PVDC is widely used for coating various substrates such as paper, cellophane, polypropylene.
vinyl plastic is used as a structural material for corrosion-resistant chemical equipment and communications, ventilation ducts, pipes, fittings, as well as for flooring, wall coverings, and insulation (penopolivinilhlorid), making baseboards, window frames and other building details.Of clear vinyl plastic bulk containers manufactured for food, bottles.
Plastic used to make insulation and sheathing for electrical wires and cables, for the production of hoses, linoleum and floor tiles, materials for wall coverings, upholstery, packaging (including food), to create an artificial skin , shoes.Transparent flexible plastic tubing used in blood transfusion systems and life support systems in medical technology.Plasticized with high heat resistance is used to produce fibers.
PVC resin is classified as thermoplastic resins.Termoplastiicheskie gum got its name from the fact that ppod heat they dissolve and soften.PVC resin has low light and heat, in addition it is very fragile, so needs to plasticize.Rastrorenie in water, gasoline or alcohol is not afraid of PVC resin.
PVC can be rightly attributed to the universal and safe materials.Many examples of the use of PVC, we can see in everyday life:tooth brushes, accessories, clothing and footwear, handrails, wall panels, etc..To improve the properties polivinilhorida for a particular purpose, PVC auxiliary components are added.For example, for PVC window special modifiers, pigments and stabilizers can improve the light resistance, overall resistance to external influences, to improve the quality of the surface or color change.Products made of PVC is difficult to ignite, they burn and endure the effects of alkalis and acids.
Wastes from the manufacture of PVC or products may be dismantled recovery and recycling of up to 5 times.The quality of the PVC remains consistently high, slightly modified only plastic shade.By the way plastics can be painted almost any color or cover a special vinyl films.This enables the realization of even the boldest design solutions.
Of course, the massive use of polyvinyl chloride obtained in the construction and repair.Very popular PVC profiles as the hull material for glazing or baffles.Products made of PVC can be used in various types of premises:from industrial to residential.Quality products PVC does not have sanitary restrictions on the use of.
All articles must pass a special polyvinyl chloride quality control.The main problem associated with the use of PVC, is the difficulty of disposal - incineration produced toxic organochlorine compounds such as dioxins.PVC so often subjected to unwarranted attacks, which had to refute by means of rigorous scientific research, which today is one of the most studied materials in the world.
