HFFR for CABLESModern world is unthinkable without cables. Cables transmit energy and ever growing amounts of data.

Halogen-free flame retardant (HFFR) or low-smoke free-of-halogen (LSFOH) polymer compounds can be used in many ways to produce safeand functional cables. Selected polymers and the corresponding flame retardants, together with some general facts about the flame-retardant(FR) systems, are presented in the table below.

For non-polar polymers, the HFFR should be used with compatibilizer/coupling agent.

COUPLING AGENTS

Wire and Cables 2021

GP range of Maleic Anhydride grafted EVA, LL, EBA, PP, HD products has been

developed for use in ATH and MH filled HFFR cable compounds:

• GRAFTABOND EVA-MAH• GRAFTABOND LL-MAH• GRAFTABOND EBA-MAH• GRAFTABOND PP-MAH• GRAFTABOND HD-MAH

Due to high grafting degree, a small loading can significantly improve the matrix

with HFFR, its mechanical properties and flame retardancy.

Assist the dispersion of additives and pigments in cable compounds and improve

the physical and mechanical properties of the compound.

Suitable for pigments, flame retardant, and anti-degradation filled cable

compounds.

Dosage: 1-5%

MASTERBATCHES FOR CROSSLINKING

Wire and Cables 2021

Crosslinking MB on porous carrier (Dry Silane) GRAFTAKIT EB-DS

Product: MB (VTMS - Peroxide -Catalyst) on porous granules

Application: PEX-b cable manufacturing

Advantages:▪ Safe▪ Technically effective▪ No scorch effect during

extrusion of cables (no premature crosslinking)

▪ NO special requirements for packaging

Dosage: 1-3%

Peroxide Crosslinking MB 12% GRAFTALEN MB EB-PER

Product: EBA + Peroxide + Co-agent + AOX (made in Solid Phase Reactor)

Application: PEX-a cable manufacturing

Advantages:▪ NO water-tree effect

Dosage: 20%

Hot-air Crosslinking MB on porous carrier GRAFTAKIT MB EB-HAXL

Product: MB (TEMPO + Co-agent +Hydroquinone + Peroxide) on porous granules

Application: Elastomer crosslinking by ”hot-air” techniques

Advantages:▪ Completely cures EPDM profile in

hot air oven tunnels. Improved physical properties are obtained due to the stronger crosslinked bonds.

Dosage: 1-3%

PRODUCTS for CROSSLINKING

Wire and Cables 2021

Crosslinking is possible by “reactive chemical pairs”.

Reactive pairs can be the following:

✓ GMA – Amine

✓ PO – MAH + NCO

✓ Amine + Epoxy Silane

GMA - Glycidyl methacrylate

NCO - Isocyanate

MAH - Maleic anhydride

PE-X = PE-g-GMA + GRAFTAKIT APTMS95% + 5%

PP-X = PP + GRAFTAKIT (Peroxide + PETA)95%+ 5%

Irreversible crosslinking

XL = PE-g-TEMPO + GRAFTAKIT IPDIPP-g-TEMPOEPDM-g-TEMPOEVA-g-TEMPO

Thermo-reversible crosslinking (High temperature resistance)

ADVANTAGES

▪ No scorch effect during extrusion of cables (no premature crosslinking)

▪ No “die build-up” during extrusion▪ No use of Steam batch (sauna PEX-b)▪ No use high temperature (as for PEX-a)▪ No use of harmful catalyst system (Tin based)▪ Long storage time (36 months guaranteed), no need for

special Alu bag packaging for (PO-g-GMA)

Processing Aid MB GRAFTAKIT EB-PDMS

Product: Polydimethylsiloxane (PDMS) based lubricant, loaded on porous Ethylene Butyl Acrylate granules

Application: In the cable industry, a smallest defect such as die lipbuild-up that forms during cable insulation can snowball into a chronicproblem that affects both the production and the quality of theproduct, causing unnecessary costs and loss of other resources.

Advantages: • Processing aid for extrusion and injection molding: reduce die

drool, torque and water absorption during processing

Dosage: 0.1 – 5%
