ABOUT SILICONES Silicones are inert, synthetic compounds with a variety of forms and uses. Typically heat-resistant and rubber like. They are generally used in Insulation, Sealants, Adhesives, Lubricants & Medical application mainly because of following properties: Higher Thermal Stability (-50°C to +205°C) Excellent Fire resistance Low Toxicity Excellent compression set Inertness to Water & Chemicals Electrical Insulation Silicones are Polymers with long chains of alternating Silicon & Oxygen atoms with Hydrogen & organic substituent's on Silicon branches Common Forms: Silicone Oil, Silicone Grease, Silicone Rubber, Silicone Resin, Silicone caulk.

FIRE & SAFETY High Intensity Fire Test IMPORTANT FEATURS Highly Fire Resistant Does not melt into liquid Extremely Low Smoke Density Lowest Smoke Toxicity Low Heat Release Free of Halogens
9
FIRE & SAFETY Suggestions for Safety Improvement Two Materials should not be compared by just one Standard Comparative Exercises on fire resistance to be conducted utilizing high intensity flame Material Melting & Gas transformation Temperature to be included Smoke Density to be compared at different fire temperatures

COMFORT Important Facts for Seat Design of IR Coaches: Coaches Designed for Long & Overnight Journeys Sleeping Option i.e. Sleeping Berths are essential Less Scope for Contouring & Ergonomical designs Flat Surface essential for sleeping Factors Important for Comfort Indentation Force Deflection Pressure Mapping
13
COMFORT INDENTATION FORCE DEFLECTION International Industry Practice (Indentation @ 40% compression) 2.5 – 5.0 kgfBed Pillows, Thick back pillows 5.0 – 7.5 kgfBack Pillows, Upholstery Padding 7.5 – 10 kgfVery Thick Seat Cushions, Wraps 10 – 12.5 kgfAverage Seat Cushions & Mattresses 12.5 – 15 kgfFirmer Seat Cushions & Mattresses 15 – 20 kgfThin Seat Cushions & firm mattresses > 20 kgf Shock Absorbing foams, Carpet underlays, Packaging etc
