PVC-U

  • PVC (polyvinylchloride) is a universal, proven, and reliable material. It was developed in the thirties of the 20th century as one of the first synthetic materials – plastics. It is a material well workable using various technologies, e.g. rolling, extrusion, depositing, or casting, therefore it is predestined for wide range of applications.
  • PVC has a unique combination of features, which can be further modified in various ways using processing additives. PVC is usually classified into softened – called most frequently PVC-P, ands hard – called PVC-U. Polyvinylchloride ranks among materials that can be recycled well and reused in the manufacture of products. Recyclable PVC is marked PVC-R. In general, products from PVC are called vinyl products.
  • PVC-U features higher strength, consistence, and hardness. It is used most frequently in products for technical applications where its physical-mechanical features together with long service life are appreciated. Typical examples of applications include:
    • transport pipes for various liquids (drinking water, waste)
    • profiles – mainly window profiles, but also smaller technical profiles for automotive or electrical industry
    • moulded products – fittings, transient and end components of conducts
    • drug and medicament packages, so-called blister packages
    • food product packages, e.g. frozen products
  • PVC itself is a powdery material. By adding various processing additives according to requirements of the final application, a mixture is prepared in the pellet form – PVC-U granulate. The granulate is processed further into a final product using thermal and pressure effects. For the abovementioned technical applications, extrusion technology (pipes, profiles), injection moulding (3D products) or moulding processes are used.
