Introducing Dow Corning® 43-821 Additive, an innovative new flame-retardant (FR) synergist from Dow Corning designed to resolve the performance degradation issues caused by high loadings of traditional FR additives in polyamide (PA) compounds. This advanced silicone-based technology now enables you to cut the amount of organic phosphorous additives used in PA compounds by up to 40 percent – while delivering excellent FR performance.
Using new patent-pending Dow Corning 43-821 Additive in your formulation can:
* Restore key mechanical properties of PA6 and PA66 resins
* Deliver a strong synergistic effect with organo-phosphorus materials
* Reduce total phosphorous content to minimize corrosivity
* Cut PA compound costs by a minimum of 10 percent
* Improve char formation and reduce heat generation
Reinforced PA compounds have been used for years in the appliance and automotive industries for enclosures, switches, fuse boxes and similar electrical applications that require high FR performance. Organic phosphorous FR additives such as aluminum phosphinate are commonly used in these compounds. However, they require high loadings and co-synergists (up to 20 percent together) to meet regulatory requirements. These loadings degrade PA’s desirable mechanical properties such as impact and elongation.
Further, aluminum phosphinate additives are frequently blended with phosphorus-based synergists such as melamine polyphosphate. This high phosphorous content can cause corrosion issues in electrical and electronic connectors.
Until now, the industry had few options:
* Replace PA with expensive, inherently FR materials such as polyether ether ketone (PEEK)
* Attempt to find synergistic approaches that reduce the level of phosphorus in the formulation
This free webinar will feature Dow Corning Senior Processing Chemist, Vincent Rerat, who will discuss the challenges of using organic phosphorous FR additives in PA6 and PA66 compounds, and present test results that demonstrate how Dow Corning 43-821 Additive can resolve them.
Senior Technical Service & Development Engineer
D. Vincent Rerat is senior technical service and development engineer for Dow Corning’s Plastics Solutions business, a position he has held since 2012. In this role, he is responsible for technical service support and silicone additives development for thermoplastics and composites with an emphasis on coupling agents, crosslinked polymers, flame retardancy and rheology and tribology modifiers.
In 2003, Vincent received a bachelor’s degree in industrial engineering with a concentration in high-performance polymers and paints from the Institute Meurice, Brussels, Belgium. He earned a master’s degree and a doctorate in chemistry from the Université Catholique de Louvain-la-Neuve in Belgium in 2004 and 2008 respectively.
