The Model N2-400 gas injection system is said to provide all of the necessary equipment to deliver a high pressure nitrogen supply (400 bar) into a foam extruder for the preparation of gas injected foam suitable for coaxial, LAN and RF cable. The system couples into the extruder through hardware that prevents the polymer melt from entering into the gas entrance stream.
