SILMALINK AZ2311

by Silma

SILMALINK AZ2311 by Silma is a powerful chain extender and branching agent for rigid or foamed PET, PBT compounds and profiles extrusion. This masterbatch increases mechanical properties of the recycled PET bottle and virgin grade. It is able to rebuild the PET chain in a linear sense to give it a new life and the same or better mechanical properties of the virgin one. It imparts a better crystalline rate and it can be recycled. The recommended dosage level is 1.5-3% on PET foam or rigid profiles. SILMALINK AZ2311 has a shelf life of one year.

SILMALINK AX2292P

by Silma

SILMALINK AX2292P by Silma is a silane-based coupling- and crosslinking agent available in thermoplastic granules form. It is compatible with EVA, POE, LLDPE and EMA/EBA. It is used in flame retardant fillers (ATH, MDH and natural mineral fillers), in combination with maleated coupling agents at a lower dosage (1-2%). At a higher dosage (4%), it is used in halogen-free flame retardant (HFFR) compounds for cables as a crosslinking agent for XL-HFFR compounds based on POE+MDH and EVA+ATH. SILMALINK AX2292P has a shelf life of 6 months.

SILMALINK AX2292

by Silma

SILMALINK AX2292 by Silma is a compatibilizer or/and crosslinker in many reactive applications to build a network copolymerization between organic CH groups and organic/inorganic OH groups in presence of accelerators like peroxide and sulfur. It is 50% of functional silane in thermoplastic granules form. It is used simply to mix with the compound pellets during compound/extrusion or injection molding. In the case of formulation with fillers like MDH, ATH and various number of silicates with the presence of OH groups, it can create a chemical bond with them during crosslinking process. It is suitable in various compounding processes like XLPE, crosslinked EVA and rubbers. It is used at a dosage from 0.5-3% it depends on the needs. SILMALINK AX2292 has a shelf life of 6 months.
