- Processing aid MB (eg PPA 5)
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 MB (eg SE 5)
are migrating agents for a thin lubrication surface layer allowing smooth handling of the manufactured product. Fast or slow migration agents are available.
- Antioxidant MB (eg AO 1)
are based on phenolic and/or phosphite chemical substances, they prevent the degradation of polymers during their processing but also when lines are stopped.
- Antiblock MB (eg AB SN15)
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.
- Multi-purposes MB (eg ABG SN10 E5)
combines different properties (for instance antiblock + slip agents).
- Antistatic MB (eg AS G10)
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.
- Thermal MB (eg IR 70)
contains some mineral agents for greenhouse films blocking infra-red radiations absorbed by the soil during day and re-emitted at night.
- Anti-UV MB (eg UV 4525)
are made of chemical molecules which can reduce or even inhibit polymers’ degradation exposed to UV radiations.
- Flame retardant MB (eg FRF 01W)
slows down the combustion process and reduces flame propagation.
- Purging MB (eg EXTRUNET HD)
allows cleaning of lines at material changes with no need to stop production.
- Dessicant MB (eg DSC)
are widely used as humidity absorber during processing of virgin polymers and recycled material.
- Smell Absorber MB (eg Keep Fresh)
absorbs fermentation gases as well as odour linked to materials fusion.
- Compatibilizer MB (eg CPAPE)
helps to mix multi-material wastes from the recycling industry.
- Peroxide MB
increases the polypropylene mfi by breaking the molecular chains.
