XYRON™ – mPPE (modified polyphenylene ether)

XYRON™ (modified polyphenylene ether or mPPE) is an engineering plastic with unique properties due to various possible alloy combinations of PPE with polystyrene (PS), polyamide (PA), polypropylene (PP), polyphenylene sulfide (PPS) or other polymeric materials.

XYRON™ PS/PPE features excellent dimensional stability, electrical properties and is suitable for PV junction boxes and connectors, contributing to downsizing.

XYRON™ PA/PPE has high heat resistance and features flowability characteristics suitable for automotive relay boxes.

XYRON™ PP/PPE has a low density and also electrolyte solvent resistance. This feature makes it suitable for lightweight automotive battery parts.

Properties of XYRON™

  • Use of Halogen-free flame retardants (UL94 V-0 to HB)
  • Outstanding heat resistance range (80 – 170 C)
  • Low density
  • Excellent dimensional stability – low mold shrinkage
  • Low water absorption
  • High resistance to acids and alkalis
  • Excellent electrical properties

Applications of XYRON™

  • Automotive industry (relay block, structural parts of lithium-ion batteries)
  • Energy industry (photovoltaic junction box, connectors)
  • Other industries (water-related applications)
