ForTii® MX2

40% Glass Reinforced, PA4T, Heat Stabilized, for Automotive applications

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.
That means a high temperature polyamide with a broad and versatile portfolio of grades that deliver high performance with a unique balance of properties.
Product

ForTii® MX2 is a high Tg PPA that outperforms in dimensional stability at elevated temperatures due to the high heat deflection temperature (HDT). MX2 has excellent fatigue performance and good chemical resistance.
