Abstract

A flame retardant comprises from 15 to 50 wt-% of one or more ethylene including EVA, ethylene alkyl acrylate, EVACO, and ethylene alkyl acrylate carbon monoxide; from 5 to 50 wt-% of a flame retardant agent; and from 15 to 70 wt-% of a filler; based on the total weight of the composition.

Description

[0001] The present invention relates to flame retardant compositions, sheets made from said compositions, and multilayer structures comprising said sheets which can be used in building applications. Background technique [0002] For panels used in buildings and architectural applications, it is desirable to use flame retardant materials to inhibit the spread of fire. Fire retardant panels cover the exterior surfaces of buildings and generally have a "sandwich" construction, two outer layers formed of metal and a middle layer of a fire retardant composition as described in the following paragraph. [0003] Important features of flame retardant compositions for building panels are high flame retardancy, excellent thermal energy and excellent mechanical properties. In order to obtain the required flame retardancy characteristics, such compositions must have a Limiting Oxygen Index (LOI) of at least 29, as determined according to ASTM D2863. Today, the usual flame retardant compo...
