Additifs pour le recyclage
Greenchemicals a développé des solutions innovantes pour faciliter le processus de recyclage. L’utilisation de stabilisateurs et d’additifs qui éliminent la présence de substances gênantes dans les polymères recyclables permet un recyclage plus efficace, préservant à la fois le polymère et les installations où se déroule le processus de recyclage.

DESCRIPTION
DÉTAILS
MB PS HT4
Physical form: MB
Hydrotalcite-based masterbatch in a polystyrene matrix. Hydrotalcite finds application as inorganic filler and is an excellent acid acceptor and stabilizer. It allows a homogenous dispersion of the active additives in the compound.
MB PS POX 20
Physical form: MB
It is an antioxidant masterbatch based on a blend of phenolic and phosphite antioxidants supported by a polystyrene matrix. It allows a homogenous dispersion of the active additives in the compound. MB PS POX 20 provides a high thermal stability during processing, it has an excellent thermal resistance and maintains the original mechanical, electrical and color properties of the compound.
MB PS 26P25
Physical form: MB
It is a masterbatch of UV absorbers in polystyrene matrix, which prevents radical polymer degradation and polymer oxidation during recycling. In addition to antioxidants, MB PS 26P25 containing a UV protection package defends PS from sunlight yellowing.
MB PS DCP STAB
Physical form: MB
It is a very strong stabilization masterbatch, especially studied for neutralizing DCP residual radicals, which are unavoidably created during recycling extrusion process. Dicumyl peroxide decomposes at 150 °C, while recycling extrusion temperature is much higher. This is the main cause of MFI increase of recycled PS.
GC B671
Physical form: PW; GR, Compacted
It is a mixture based on phenolic antioxidants. It is particularly suitable as a process synergist and guarantees very high and long-lasting thermal stability.
MB PS HT4
Forme physique : MB
Séquestrant d’acide dans le liant PS. Il réduit considérablement l’effet négatif causé par les halogénures d’hydrogène libérés par les FR à haute température.
