Nanoclay Wire & Cable Formulation Issues


Gendon, a major wire and cable company part of RSCC/Marmon (Berkshire Hathaway) emailed me with a problem. They were working on a polyolefin-based FR cable formulation that contained magnesium hydroxide (MDH) plus a nano-clay. After extrusion they noticed that the nanoclay gave a green tinge to the product. They had tried adding more process stabilizer but the color would not go away.


The company was not a client but the question came from a friend, so I suggested an additive he should try. It was one I’d used before to prevent discoloration in plastics due to nanoclay.


The next morning I was delighted to receive an email saying that the discoloration was completely prevented using the additive I had recommended. They were so happy with the solution but not prepared to pay me for the work, so instead I am posting it here so at least I can get some benefit from the story. I like helping people but it’s even nicer when you get paid!
