Jiangsu Yoke Technology Marketing Presentation PhireGuard DR-92 1

PhireGuard DR-92: a new Flame Retardant Technology 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 2

PhireGuard DR-92 in Details Typical Properties  Slightly yellow transparent liquid  Phosphorus content = 11%wt, Chlorine content = 17%wt  Viscosity = 450 cPs  Acid value < 0.5 mgKOH/g  Water content > 0.1 %wt  Does contain some TEP used as viscosity regulator 3

In Summary 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 9
