Ribbon Flow : Adiprene® RFA 1001 - 2 Component Fixed Hardness System. RFA 1001 cured with individual RFB curatives is a high performance PTMEG based system providing PU elastomers at hardness levels of 70A, 80A, 90A & 95A. With the use of 2 ‘fixed’ material components, one RFA prepolymer and one RFB curative, the following advantages are achieved: • No requirement for moulds for casting of rolls. • Lower energy costs - no post-cure & minimal heating. • Reduced waste - fewer defects & less overbuild. • Lower labor costs. • Shorter turnaround times / higher productivity. • MbOCA Free chemistry. • Mercury Free catalyst technology. • Avoidance of numerous material changeovers from different formulation
