XPS Sheets
Adding value to insulation
Extruded Polystyrene Foam (XPS) is strong and durable, providing high-performance thermal insulation for residential and industrial buildings when used in inverted roofs, floors or ceilings.
Leveraging our extensive experience in this field, we have developed a range of solutions that offer added value to XPS producers, helping them meet the ever-changing demands of both the insulation sector in particular and the wider construction industry.
High-concentrated HBCD-free flame retardant masterbatches
With the use of HBCD restricted by regulations in the EU, North America and other western countries, polymeric brominated FR has become commonly used as a replacement. As a leading producer of FR masterbatches for XPS, we were one of the first to introduce HBCD-free solutions to the market, in compliance with new FR standards.
High stabilization flame retardants for XPS
Recognizing that different XPS producers require different thermal stability, we develop tailor-made solutions that meet stringent thermal stability requirements, as well as low and medium thermal stability packages.
Questions and Answers About XPS Foam
Flame retardants are additives incorporated into XPS foam to enhance its fire resistance. They help slow the spread of flames, reduce fire intensity, and ensure the foam meets necessary fire safety standards. This is particularly crucial for building insulation, where fire performance is a key safety concern.
There are three primary categories of flame retardants used in XPS:
- Polymeric Flame Retardants (pFRs): These are highly effective flame retardants based on grafted brominated butadiene/styrene block copolymers.
- Non-Polymeric Flame Retardants: Typically based on tetra bromo bisphenol A (TBBA), these materials offer excellent thermal stability.
- Blended Flame Retardants: A combination of both polymeric and non-polymeric flame retardant.
