A Brief Guide for Choosing your Flat Ejection Rubber:
T-75 or MR-75 (brick red): Extra firm ejection material, very popular for cartons, labels, and other thin substrates. T-75 is traditional open-cell; MR-75 is a neo/micro-cell.
6110 or 03500 (red): Extra firm ejector used for cartons, labels and other thin substrates with fast recovery. Both are open-cell.
RD-73 or Red Rhino (red): Firm ejector used in both rotary and flat die-cutting for a wide range of substrates.
6118 or 06500 (red): Firm ejection rubber used for corrugated or thicker substrates. Both are open cell.
B-65 or MR1100 (black): Medium density ejector perfect for thick substrates and hand-fed, flat die-cutting. B-65 is open cell; MR1100 is neo/microcell.
6220 or 02700 (tan): Medium density ejector used for thicker substrates and hand-fed flat die-cutting. Both are open-cell.
K-60 (tan): Similar to B-65 or MR1100, but for thicker substrates. Open-cell.
6320 or 15700 (tan): Similar to 6220/02700, but for thicker substrates. Open-cell.
Cork or 13500 (brown): Cork and rubber composite that is very durable and used for crushing.
Green/Groovy Grilla (green): Strong ejector suited for narrow slot ejection in flat die-cutting, and in rotary applications, is good for interior scrap and lead and side trim ejection.
Dura-Bull or Super Strip (white/tan): Popular slot ejector in both flat & rotary die-cutting. Use sparingly.
