PFR-18 is an extremely flexible, flame-retardant polyether urethane material that has a soft rubber-like texture. PFR-18 jacketing offers exceptional ruggedness, resistance to abrasion and most fluids, while exhibiting high flexibility in virtually any demanding environment. The material meets Mil-I-3930/21 specifications and is an excellent choice for many nuclear, aerospace and military applications where PVC materials are not permitted. PFR-18 can be configured for round, flat and rectangular cable configurations and can be combined with most Zippertubing EMI Shielding materials.
