The Technology
The copolymerization of low density polyethylene (LDPE) with acrylates is known and the resulting polymers are used in a vast number of industrial applications such as flexible and liquid packaging laminates, automotive seals, gaskets, hoses, etc. Flame-retarded polyolefins are widely used nowadays. The flame-retardant agent is added to the already synthesized polymer and is not chemically bound as part of the polymeric back-bone. The addition of a flame-retardant compound either as an additive or filler to a polymer has the disadvantages of leakage, and the inability to tailor it specifically to the polymer properties. Therefore, there are clear and specific advantages towards polymers in which the flame-retardant agent is an integral part of the polymeric skeleton.
Particularly, Brominated acrylic homopolymer is used today as a fire retardant additive in the plastics industry. The technology offers polymeric products of novel polyolefins containing a brominated acrylic comonomer.
Advantages
- Improved compatibility between the flame-retardant and the polyolefin matrix
- Environmentally more friendly since additives do not leach during usage and waste disposal
Applications and Opportunities
- Flame-retardant agent as an integral part of the polymeric skeleton
