Phosflex® 375

Phosflex® 375 is a proprietary plasticizer blend that contains an alkyl diphenyl phosphate and a triaryl phosphate ester, which offer reasonable plasticizing performance alongside enhanced flame retardant properties.
This blend is useful in a number of PVC applications including wallcovering, transparent sheet goods, laminated products or any other flexible vinyl composite requiring a high degree of flame retardancy. In general, Phosflex® 375 exhibits excellent plasticizing characteristics and compares well to isopropylated TPP phosphate esters (PIP (3:1)) that are regulated by EPA.

Key Benefits

  • Excellent flame retardant efficiency
  • Transparency during FR effect
  • Plasticizing efficiency comparable to isoporyletad TPP (PIP (3:1))
  • Good thermal stability
  • Excellent compatibility in PVC and engineering resins
