Nylon

Printer Friendly Version


Nylon resins are typically used in applications requiring heat and chemical resistance, as well as, toughness. Some examples include under-the-hood automotive components, electrical connectors for the telecommunications and computer industries and components of medical devices. Nylon products can be found in virtually every industry. Parts in a broad range of colors can be produced with most nylon resins.
