has launched a new silicone technology at Chinaplas 2017, designed to resolve mechanical performance degradation and corrosion issues caused by high loadings of traditional flame-retardant additives, such as organic phosphorous, in polyamide compounds.
The silicone additive cuts the amount of organic phosphorous additive in PA6 and PA66 compounds by 40 per cent, still providing high levels of flame retardation. The new flame retardant synergist used at low levels (1 to 2 per cent), delivers important benefits for compounders and electronic component manufacturers.
43-821 restores key mechanical properties of PA resin, minimising corrosion of metallic parts that contact the formulation and lowering compound costs by 10 per cent or more. It is the first in a totally new product family, and is now featured at Dow Chemical’s Chinaplas booth, 10.2G41.
Christophe Paulo, Global Segment Leader for Plastics, said: “Balancing performance and cost is a compounding challenge that our new Dow Corning 43-821 Additive is helping to address head on.
“Not only does this new product optimise highly filled, flame-retardant PA compounds, but it also delivers cost advantages in three major ways - by reducing the required amount of organic phosphorous additive, by delivering high performance at very low loadings and by avoiding the need for over-engineered inherently flame retardant materials. Dow Corning 43-821 Additive is a prime example of how the company continues to innovate highly specialised additive technologies that meet very specific customer needs.”
