General Information

ForTii® is a breakthrough high temperature polyamide with halogen-free and halogen containing flame retardant grades for demanding applications in the electronics, lighting, automotive, white goods, industrial and aerospace industries.
We developed ForTii® in close co-operation with leading OEMs and tier 1 connector and socket manufacturers to ensure we give our customer what they want – and need.
ForTii® Ace is a PPA with a high Glass Transition Temperature, with extreme chemical resistance, suitable for applications that need high mechanics at elevated temperatures.
Product
ForTii® Ace MX51 is a PPA with unique fatigue performance and chemical resistance. The high aromatic content and high Tg lead to excellent part stiffness and low creep, even up to 150°C. Moisture uptake occurs slowly with very limited impact on dimensions.
