What is PoLinker™?
A functional polymer used in formulation of compounds as coupling agent, polymer modifier, dispersing aid, adhesion promoter or hot melt adhesive. The PoLinker family includes many grades which based on different polymers to match what they needed. Certain grades have different product types depending on the applications.
Coupling Agent
Using PoLinker in thermoplastic compounds as a coupling agent to improve the mechanical properties.
Polypropylene functionalized with maleic anhydride (MA) can be a coupling agent for polypropylene compounds with glass fibers, carbon fibers or natural fibers. It helps the compatibility between polypropylene and fiber, thereby improving its tensile strength and impact property.

PL1010 | PP | 80 (190℃/2.16kg) |
Polymer Modifier
Thermoplastic elastomers grafted maleic anhydride (MA) used for polymer modification which improve their toughness.
Polyolefin elastomer functionalized with maleic anhydride (MA) mainly used for polyamide toughening.
Polyolefin elastomer functionalized with maleic anhydride (MA) mainly used for polyamide toughening.
SEBS polymer functionalized with maleic anhydride (MA) is an efficient impact modifier of polyamide (PA), polycarbonate (PC) and PC/PBT with high thermal stability.

PL5110 | EPDM | 0.4 (190℃/2.16Kg) |
PL6523 | SEBS | 18 (230˚C/5Kg) |
Adhesion promoter
An adhesion promoter will act effectively at the interface of different substrates to chemically and physically wed these dissimilar materials into a strong cohesive bond structure. PoLinker can be an adhesion promoter between polymer and polymer, or polymer and inorganic substrate to enhance adhesion between the two materials.

Hot Melt Adhesive
PoLinker hot melt adhesives originates from functionalized thermoplastic olefin (TPO) which offer a bonding solution between TPO and other substrates as a tie layer by lamination or co-extrusion.
