Pentaerythritol (PER) Flame Retardant Grade

Featured inFlame Retardants

Pentaerythritol (PER) flame retardant grade is a high-purity polyol specifically used as the carbonific (carbon-forming) component of intumescent flame retardant systems for coatings, polyolefins, and thermoplastic composites. It reacts with the acid source (typically ammonium polyphosphate) upon decomposition to produce a cross-linked, thermally insulating char. High-purity FR grade PER with minimized mono-PE content is preferred for consistent char formation and coating film integrity in demanding fireproofing applications.

Uygulama Alanları

  • Solvent-borne intumescent structural steel fireproofing coatings (30-year fire protection)
  • Waterborne intumescent wood and timber coatings for Class 1 surface spread of flame
  • Halogen-free intumescent FR polyolefin compounds for cables and automotive
  • Passive fire protection boards, batts, and blankets with charring binder
  • Intumescent pipe collars and cable transit fire stop systems

Ürün Özellikleri

  • High mono-PE purity (≥98%) ensures consistent char formation kinetics and coating film quality
  • Four hydroxyl groups per molecule deliver maximum theoretical char yield in IFR systems
  • Low ash content (<0.005%) prevents yellowing and discoloration of white intumescent coatings
  • Well-characterized reaction kinetics with APP enable precise formulation of intumescent systems
