PhireGuard DR-92: a new Flame Retardant Technology

2

General Description

 Original FR technology*, particularly suited for the rigid PU foam segments  Based on Cl and P as active FR centres.  Alternative to FR commonly used in PUR and PIR foams, in particular TCPP  High M.Wt., low volatility Flame Retardant, durable FR protection  Compatible with double belt panel lamination, discontinuous panel production,

block and spray foams, pour in place…

An alternative to TCPP: PhireGuard DR-92 !

* Technology being patented

PhireGuard DR-92 is a flame retardant particularly suited for the production of rigid polyurethane and polysocyanurate foams. In comparison with TCPP, DR-92 offers the following advantages:

 Depending on formulations details, some 10% fire protection improvement  Less smoke emission  Less foam plasticization

Whilst impacting the foam process and final foam properties in a similar way than TCPP does
