Fatra has been dealing with plastics for more than 80 years. During this period, we have gained immense experience with polyvinylchloride (PVC). This polymer is exceptional because of its huge spectrum of applications. This is demonstrated by traditional Fatra products such as inflatable toys, floor coverings, waterproofing membranes, and an inexhaustible number of profiles from hoses to hard tubes. The macromolecular structure of PVC provides very good chemical resistance, low flammability, good electro-insulating properties and the option of secondary processing (recycling). The material can also be glued and welded and its colour may be set to any shade including transparent variants.

Polyvinylchloride alone is however almost unworkable without necessary additives.

Different formulas of mixtures thus enable us to produce from PVC anything from elastic packaging to a hard window frame.

Our team is engaged in the development of PVC mixtures and the production of softened and hard PVC granulates. We provide many well-proven material solutions for various types of products and technologies, we use laboratories with high-quality facilities, and we prepare tailor-made PVC granulate for our customers.

TECHNOLOGY SPECIFICATION

The basis of the granulate production technology at Fatra, a. s., is the two-stage homogenisation of a loose mixture in Plas Mec and Promixon fluid mixers. The mixers, alongside our many scales and conveyors, are controlled by a central computer using Siemens software.

After stirring, the mixture is transformed into a granulate using double-screw Bausano granulation lines.

DEVELOPMENT AND LABORATORIES

Our research laboratories have at their disposal many state-of-the-art measuring devices operated by experienced laboratory assistants.
This enables us to:

  • ensure the constant quality of all purchased raw materials
  • analyse the properties and composition of competitive samples of granulates and profiles
  • suggest complete formulas for specific technologies and applications
  • provide complete customer service on the granulates we supply
