Fine-Blend® SAG-008 distributed by DKSH is a polymer chain extender. It is a random styrene-acrylonitrile-glycidyl methacrylate terpolymer with colorless bead appearance.

• It can provide superior chain extender solutions for recycled nylon, polyester, polycarbonate and other already biodegradable polycondensated resin.
• It maximizes the quality of the recycled polycondensated resin, improve the mechanical, thermal and processing properties.
• It can be processed over a wide range of conditions.
• Fine-Blend® SAG-008 is available in Europe, North America and Asia Pacific.

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.

Marble Elite® Gamma Q by Huber Engineered Materials acts as a chain extender. It is a high-purity, granular calcium carbonate grade with a carefully controlled particle distribution.
