Sandwich panel production lines and equipment

To guarantee the quality of sandwich panels and PIR Plita^®, in 2016 ProfHolod opened its own research center for developing customized PIR systems to European standards

• 

  Before a line trial, the R&D Center runs up to 8 experiments to check physical and mechanical properties, foam formation timing, reaction temperature profiles, flowability and rise rate. Outgoing in-plant inspection complies with the EN 14509 standard, which underpins the quality of all European PIR and PUR sandwich panels

• 

  Our Research Center performs inspection to the European standard EN 14509.

  
  

  Destructive tests cover:

  
  
  • tensile strength
  • compression
  • core shear
  • foam span bending
  
  

  Non-destructive tests include:

  
  
  • artificial ageing test
  • thermal conductivity measurement
• 

  Since 2016 the customized PIR Premier blend has guaranteed the quality of sandwich panels and PIR Plita®:

  
  
  

  thermal conductivity and physical and mechanical properties. It was created specifically for the lines installed at our plant.

  
  
  

  The PIR Premier blend is certified to the European standard EN 14509. All sandwich panels with PIR Premier have carried the CE mark since 2017.

  
  
  

  To improve control of one of the system's key components, polyester polyol, we held negotiations with 10 reagent suppliers around the world and signed a contract with European companies whose products are used by the world's largest concerns: BASF, Dow, Huntsman, Coim, Evonik, Covestro

  The H&S Anlagentechnik mixer installed on our line in 2015 provides high-quality mixing and dosing of components to European standards. The resulting polyol blend is fed under high pressure together with catalysts, pentane and isocyanate to the pouring head of the continuous line. The mixer also lets us produce primer polyol and any catalyst mixtures
