Optislip ER (formerly Crodamide) is a bio-based primary amide additive in pastille form, providing an extremely effective slip agent in polyolefin films. Optislip ER is the preferred amide for use in LDPE, LLPDE and PP due to its good oxidative stability, low volatility and excellent slip performance. Optislip ER (Pastille) also imparts anti-blocking properties, preventing Polyamide and EVA hotmelt adhesive granulates or films sticking together.
