HFFR for CABLES
Modern 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 safe
and 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
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%

GMA - Glycidyl methacrylate
PRODUCTS for CROSSLINKING
Crosslinking is possible by “reactive chemical pairs”. NCO - Isocyanate
Reactive pairs can be the following:
✓ GMA – Amine
✓ PO – MAH + NCO MAH - Maleic anhydride
✓ Amine + Epoxy Silane
PE-X = PE-g-GMA + GRAFTAKIT APTMS
95% + 5%
PP-X = PP + GRAFTAKIT (Peroxide + PETA)
95%+ 5% ADVANTAGES
Irreversible crosslinking
▪ No scorch effect during extrusion of cables (no
premature crosslinking)
XL = PE-g-TEMPO + GRAFTAKIT IPDI ▪ No “die build-up” during extrusion
PP-g-TEMPO ▪ No use of Steam batch (sauna PEX-b)
▪ No use high temperature (as for PEX-a)
EPDM-g-TEMPO
▪ No use of harmful catalyst system (Tin based)
EVA-g-TEMPO ▪ Long storage time (36 months guaranteed), no need for
special Alu bag packaging for (PO-g-GMA)
Thermo-reversible crosslinking (High temperature
resistance)

MASTERBATCH FOR PROCESSING AID
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 lip
build-up that forms during cable insulation can snowball into a chronic
problem that affects both the production and the quality of the
product, 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%
