ForTii® F12

40% Glass Reinforced, PA4T, Electro-friendly, Halogen free and free of red phosphorous

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® F12 has excellent balance of stiffness and toughness, suitable for high mechanical loaded application such as power connector or EV parts. F12 has high RTI electrical rating of 140°C at 0.75 mm and shows JEDEC Level 2 performance, enabling SMT process without deformation and low risk on blistering.
