Antiblock : are made of mineral fillers with a very small diameter which modify the surface of manufactured products , especially films, for instance to ease the unwinding of rolls, the opening of bags or to improve ink printability.
Dessicant : are widely used as humidity absorber during processing of virgin polymers and recycled material.
Anti-UV : are made of chemical molecules which can reduce or even inhibit polymers’ degradation exposed to UV radiations.
Purging : allows cleaning of lines at material changes with no need to stop production.
Processing aid : creates a coating on the machines’ metallic walls to prevent the melt fracture. They reduce die deposits as well as the “shark skin” effect.
Slipping : are migrating agents for a thin lubrication surface layer allowing smooth handling of the manufactured product. Fast or slow migration agents are available.
Antioxidant : are based on phenolic and/or phosphite chemical substances, they prevent the degradation of polymers during their processing but also when lines are stopped.
Multi-purposes : combines different properties (for instance antiblock + slip agents).
Antistatic : are fast or slow migrating agents moving to the surface of manufactured products to evacuate electrostatic charges. They can also be used as demoulding agents.
Flame retardant : slows down the combustion process and reduces flame propagation.
