Recorded Wednesday, May 24- Presented by Dow Corning
Introducing a new, innovative Dow Corning flame-retardant (FR) synergist 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 the new 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 the new Dow Corning additive can resolve them.
