SILMALINK AD2238

SILMALINK AD2238 by Silma is a powerful chain extender and branching agent. This masterbatch is suitable for PET/PBT/PCL/PA6/PA12 compounds and flexible profile extrusion. It increases mechanical properties like impact strength and rigidity. It also gives melt flow reduction and increase in viscosity & crystalline rate. The recommended dosage level is 1.5-2% on PET foam or rigid profiles. In compounding or directly in profiles extrusion the suggested dosage is from 1.5-3% max. to obtain improved viscosity index, reducing MFI and better mechanical properties. SILMALINK AD2238 has a shelf life of one year.
