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.

DURABILITY
Suggestions to achieve Higher Durability
• Conduct Automotive Standard
IS: 7888; 70 ° C, 22 hrs; 0% Thickness Loss
100 ° C, 22 hrs; 0% Thickness Loss
• Comparison of practical installations in the coaches on more frequent basis

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
