PVC production is of ancient origin – the first patent dates back to the early 1900s. The continuous innovation from an industrial point of view gave a much-needed boost to improve PVC production through an increasingly rapid and quality polymerization process, making it possible to manufacture materials with different molecular weights to be suitable for satisfying specific performance. PVC is especially used to manufacture packaging, medical and surgical accessories, building materials, as well as for design, fashion, transport, and even agriculture applications.
PVC is one of the most versatile and used plastic materials worldwide. The abbreviation PVC stands for polyvinyl chloride, or polyvinylchloride, that is the polymer of vinyl chloride.
PVC’s pure version is rigid. When it comes to applications, it is greatly versatile, for it is possible to mix – even in high proportions – inorganic compounds and plasticizers such as phthalic acid esters that make it highly flexible and mouldable.
It’s particularly stable if used for technological applications at room temperature. It must always be processed in suitable and properly built facilities. Moreover, PVC is one of the easiest materials to recycle.
Filtec’s compound granulation systems process both flexible and hard PVC successfully.
The technology used makes it possible to minimize the cutting force that is detected in most underwater pelletizers. The result is a clear advantage for clients, for they can process materials with excellent physical properties thanks to a lower cutting force and an underwater PVC rapid cooling.
Granule size can vary from min. 0.7 mm to max. 5 mm – depending on the specific material and application needs.
