Abstract
A polymeric composition includes 15 wt % to 95 wt % of a non-polar ethylene-based polymer based on the total weight of the polymeric composition; 0 wt % to 35 wt % of a polar ethylene-based polymer based on the total weight of the polymeric composition; and 5 wt % to 50 wt % of an intumescent flame-retardant mixture based on the total weight of the polymeric composition. The intumescent flame-retardant mixture includes piperazine pyrophosphate and from 15 wt % to 55 wt % of a phosphoric acid compound based on the total weight of the intumescent flame-retardant mixture.
Claims12
A polymeric composition, comprising:
- 5 wt % to 95 wt % of a non-polar ethylene-based polymer based on the total weight of the polymeric composition;
- 0 wt % to 35 wt % of a polar ethylene-based polymer based on the total weight of the polymeric composition;
- and
- 5 wt % to 90 wt % of an intumescent flame-retardant mixture based on the total weight of the polymeric composition, wherein the intumescent flame-retardant mixture comprises piperazine pyrophosphate and from 15 wt % to 55 wt % of a phosphoric acid compound based on the total weight of the intumescent flame-retardant mixture.
