Optislip BR (formerly Crodamide) is a bio-based anti-block additive effective in a wide range of polymers in plastic and coating applications. It retains excellent anti-blocking properties at high temperatures. Adding Optislip BR allows use of less inorganic anti-block, such as talc or silica, and therefore maintains film clarity. Optislip BR can be used in combination with Optislip ER to give slip and anti-block, whilst maintaining clarity.
