Slip & Anti Blocking Additives

Calcium & Minerals (India) offers Slip and Anti Blocking Additives. Slip additives are added to reduce the surface coefficient of friction of polymers and are used to enhance either processing or end applications. High and low level slip additives are available and immediate and slow acting performance can be engineered into the master batch. Food contact approved grades are available. Combinations with antistatic and anti block products for use in the film industry offer cost effective, multi-use master batches. Anti blocking additives: polyolefin and other plastic films have a tendency to adhere together, often making it difficult to separate layers. This adhesion between film layers, called blocking, is an inherent property of some polymers. Anti blocking additives can be added to the plastic to minimise this adhesion and so lower the blocking force between layers. Once compounded into a plastic these additives create a micro rough surface, which reduces the adhesion between film layers and lowers the blocking tendency.
