Product Description
Ultramid 8281 HS is an unreinforced, plasticized, heat stabilized nylon 6 rotomolding resin. Developed for applications requiring increased flexibility. It is also available in natural, black and can be painted. It exhibits excellent balance of engineering properties including strength, flexibility, and toughness combined with excellent abrasion resistance and self-lubricating properties associated with PA6. In addition, the heat stabilizer system extends its retention of properties at elevated temperatures. Chemical resistance is excellent to gasoline, diesel fuels, greases and oils. All data is from injection molded specimens with the exception of Drop Weight Impact.

Applications:
Ultramid 8281 HS is generally recommended for applications such as fuel tanks, chemical storage tanks, hydraulic oil reservoirs, cyclones, heat resistance containers, and air ducts.
