DuPont™ Nomex® Type 994, 250 mil Nominal Thickness Rigid Aromatic Nylon Board
Categories: Polymer; Thermoplastic; Nylon (Polyamide PA); Nylon, Aromatic

Material Notes: Type 994 is a densified, rigid board which has a unique combination of superior resistance to compression, even at elevated temperatures, along with relatively high oil absorption characteristics. This combination results in a product which is especially useful as spacers or other structural components in liquid-filled systems.

DuPont and Dow have completed their merger. This product line remained with DuPont.
