Halogen Free FR systems

HFFR

In halogen free compounds the flame retardants of choice are mostly minerals such as ATH and/or MDH, polymer base (especially for cable) would usually be EVA and Polyolefins. Here the challenge can be two-fold, very high loadings of minerals could cause extrusion problems, as well as a tendency for running or dripping during burning.

Sidistar® will be your ideal solution to improve the char formation (strength and structure) because of its spherical shape. Due to this morphology Sidistar® also will improve the extrudability of highly filled compounds.
