HALOGEN FREE FLAME RETARDANT POLYMERIC COMPOSITIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18568360 titled 'HALOGEN FREE FLAME RETARDANT POLYMERIC COMPOSITIONS

The method described in the abstract involves melt blending an ethylene-silane copolymer with a halogen-free flame retardant masterbatch to form a polymeric composition, which is then processed into particles.

The ethylene-silane copolymer is a random copolymer of units derived from ethylene and vinyltrimethoxysilane, with a vinyltrimethoxysilane content of 0.5 wt% to less than 2 wt%.
The halogen-free flame retardant masterbatch contains halogen-free flame retardant dispersed in an ethylene vinyl acetate copolymer.
The resulting polymeric composition is suitable for various applications requiring flame retardant properties.

Potential Applications: - This technology can be used in the production of flame retardant materials for construction, automotive, and electronics industries. - It can also be applied in the manufacturing of cables, wires, and other products requiring fire resistance.

Problems Solved: - Provides a halogen-free flame retardant solution for polymer compositions. - Enhances the flame retardant properties of the materials without compromising other characteristics.

Benefits: - Improved fire safety in various applications. - Environmentally friendly solution without halogen content.

Commercial Applications: - Flame retardant materials for building construction. - Fire-resistant components for automotive and aerospace industries. - Electrical insulation products with enhanced safety features.

Questions about the technology: 1. How does the presence of vinyltrimethoxysilane in the copolymer enhance flame retardant properties? 2. What are the specific advantages of using a halogen-free flame retardant masterbatch in this process?

Original Abstract Submitted

A method of forming a polymeric composition includes the steps of melt blending an ethylene-silane copolymer and a halogen free flame retardant masterbatch comprising halogen free flame retardant dispersed in an ethylene vinyl acetate copolymer to form the polymeric composition, wherein the ethylene-silane copolymer is a random copolymer of units derived from ethylene and vinyltrimethoxysilane and further wherein the copolymer has a vinyltrimethoxysilane content of 0.5 wt % to less than 2 wt % based on the total weight of the ethylene-silane copolymer; and processing the polymeric composition into a plurality of particles.
