Anti-block additives, such as the Crodamide range, reduce blocking at the surface of polymer films and other plastic articles to allow easier processing and handling. Blocking is related to slip, however, slip involves the sliding of two surfaces over each other, blocking is the adhesion of those surfaces. Our anti-blocking additives reduce surface friction allowing easier separation of polymer surfaces. This can give an advantage in end-use applications such as opening plastic bags.
Crodamide anti-blocking additives
Traditionally inorganic anti-blocks such as silica are added to polymer films to reduce blocking and aid separation. However, these types of additives can cause a reduction of clarity in transparent films. Our anti-blocking additives work best in combination with low levels of inorganic anti-block, which results in improved clarity.
