Cogegum GFR 380 for Cable Jacketing
Halogen-Free FR Compound
Solvay Specialty Polymers has expanded its family of Cogegum cross-linkable, halogen-free flame retardant (HFFR) compounds for cable jacketing for the railway, shipboard, industrial, and oil and gas industries. The new polyolefin grade, Cogegum GFR 380, delivers greater flexibility and superior flame resistance compared to competitive silane-grafted HFFR materials.
Cogegum GFR 380 addresses the inherent limitations of silane-grafted HFFR materials which are typically stiff because of the lack of a plasticizer component. With a 38 Shore D hardness, the new grade is softer and more flexible than competitive silane-grafted HFFRs which typically exhibit a 45 to 50 Shore D hardness. This is particularly important in railway and shipboard applications where cable space is narrow and bending ability is a key advantage.
The new polyolefin grade also provides superior flame retardant properties compared to competitive silane-grafted HFFRs. During burning, the material’s char is compact and protects the cable from accelerated burning. It also offers the same chemical resistance as previous grades to such substances as oil, fuels, alkalines, acids, and service fluids.
Cogegum GFR 380 incorporates a masterbatch that contains special additives to improve cross-linking action and aging. An anti-ultraviolet (UV) agent for enhanced weatherability is also part of the formulation. The material is rated for use up to 90°C (194°F) and can be adapted for certain applications up to 105°C (221°F).
Cogegum GFR 380 is commercially available throughout the world. Power, data, and signal cables are among the key application areas. Solvay said the technology platform will be expanded to include other silane-grafted HFFR materials in the near future.
