THE NEW POLYBOND™ 3349
POLYBOND™ 3349 coupling agent allows for high load rates of HFFR without sacrificing the tensile strength, tensile modulus, and elongation properties of your compounds. Halogen-free flame-retardant wire and cable compounders will see outstanding flame-retardant dispersion and melt flow stability. High-demanding environments, such as automotive wire (EV and combustion engines), building and construction applications require.
How? POLYBOND™ 3349 aids by giving improved dispersion and adhesion of the halogen-free flame-retardant cable and wires (HFFR), helping regain the base polymer's physical properties and improve overall performance.
SI Group's broad range of POLYBOND ™ coupling agents improves the mechanical performance of HFFR wire and cable compounds by strengthening the bond between the polyethylene polymer insulation and the filler. POLYBOND ™ polymer additives enhance physical properties, gel resistance, dispersion, and flame-retardant performance.
