5000-2.5 TRX Pouring Foam
Quick Overview
5000-2.5 TRX pouring foam is a water-blown foam designed especially for pour casting into molds to create very intricate very diverse parts. This pouring foam is blended to specifically designed re-activity molding times such as creme time, gel time, tack-free and overall cure time. The foam contains a bio-based polyol. This pour casting foam may be used in a variety of applications in very diverse industries such as architectural wall and decorative part moldings, furniture and toy markets, specialty part moldings etc.

Technical Application Data
5000-2.5 TRX is a two component mixture: 1A to 1B mix ratio pbv. This foam is normally mixed and dispensed using a plural component machine. Typical working times are: creme-30-40 sec., gel time-90 sec and tack-free-120 sec. Caution must be used in heavy thick pours where high exothermic temperatures of 300F may be seen. Substrate must be dry with relative humidity < 85%. Volumetric expansion of these foams are dependent on many factors including proper mixing, equipment and temperatures of the resins, substrate and ambient. Recommended mold temperatures are from 100F to 120F. This foam is not UV stable and not intended for direct exterior weatherability applications.
