Saint-Gobain: FST certified fluoropolymer materials

Rulon J was recently certified for mass transit applications such as in trains and aircraft in regards to specific safety requirements for flammability, smoke, and toxicity (FST). Specific flammability and smoke density testing were performed according to ASTM standards E162-11 (surface flammability of materials using a radiant heat energy source) and ASTM E662-09 (standard method for specific optical density of smoke generated by solid materials). Toxicity testing was performed according to Boeing Specification Support Standard BSS 7239 for toxic gas generation by materials on combustion and meets the requirements of Specification section T. S. 205.A.3.c for maximum toxic gas release limit.The Rulon J material has very good wear resistance, is non-abrasive and has, according to the company, one of the lowest coefficient of friction of most reinforced PTFE materials. The Rulon brand consists of a family of materials that are mostly composed of PTFE-based resins, and products include bearings, rings, tapes, formed parts, basic shapes, and wear components. Primarily used in mechanical, electrical and chemical applications, The Rulon material withstands a variety of harsh environments such as extreme dryness, cryogenic temperatures, water, steam, and hydrocarbon fuel.  Rulon ball bearings were installed on the NASA rover Curiosity that was launched to Mars in November 2011.Hall 8a, stand H33
