Optilsip ER (formerly Crodamide) is a bio-based primary amide additive in bead form, providing an extremely effective slip effect in polyolefin films, and an effective anti-blocking effect in adhesives. Due to its good oxidative stability, low volatility and excellent slip performance, Optislip ER (Bead) is the preferred amide for use in LDPE, LLPDE and PP polymers. Optilip ER (Bead) also provides anti-blocking properties to Polyamide and EVA hotmelt adhesives, preventing adhesive granulates or films sticking together.
