ForTii® NMX33

50% Glass Reinforced, PA4T, Suitable for NMT, Suitable for PVD

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®
NMX33 offers excellent adhesion to NMT treated metals and high mechanical
performance in metal/plastics bonding. NMX33 also has a high HDT resulting in a
good thermal resistance, supporting high temperature secondary processes such
as high temperature PVD.
