pinfa76 YYonezawa


Yutaka Yonezawa, Adeka, presented non halogenated FRs systems for exterior applications of polyolefins, such as polypropylene. These PIN FR solutions act by intumescence, creating a protective layer which shields the polymer from heat and prevents diffusion of the pyrolysis gases necessary to feed fire.

The PIN FRs offer lower smoke release, reduced smoke toxicity, and additionally do not deteriorate HALS (hindered amine light stabilisers), so enabling to maintain UL94-V0 after 3 000 hours of weathering.
