FR4810 is a thermoplastic, low smoke zero halogen (LSZH) flame retardant, black jacketing compound combining with flexibility and exceptional fluid resistance. The composition is based on the elements Carbon, Hydrogen, Oxygen, Silicon and Calcium. Compounds based on these elements will therefore be the only significant constituents of the combustion fumes. Other elements may be present in concentrations less than 0.1%.

Its excellent flame retardancy is achieved by an inorganic filler and a novel char-forming additive.

The high operating temperatures and durability (abrasion resistance, hardness) of FR4810 makes it an attractive solution for energy cables installed in industrial areas, tunnels, ducts The ability of this compound to be used for both internal and external applications is valuable as it avoids the requirement of cable splicing at building service entrances. It can be used in areas sensitive to smoke or corrosive and toxic combustion products. In general, FR4810 has sufficient flame retardancy to satisfy bunched cable vertical burning tests.

FR4810 meets the applicable requirements as below when processed using sound extrusion practice and testing procedure:
  • BS 6724
  • BS 7655 LTS2
  • VDE 0207 Teil 24 (HM4)
