Note:
All the above data are got from the examination by Fire-extinguish
Apparatus Quality Inspection Center of Jiangsu Technology
Supervisor and Quality Inspection Center of State Glass
& Fibre Academic. |
Characteristics:
Less hydrosopicity: excellent heat preservation
Better flameproof: excellent flameproof property
Strong heat insulation: less coefficient of heat conductivity
Easy-machining£ºexcellent forming plasticity
Large temperature range£º-80¡æ¡«+80¡æ
Excellent quakeproof£ºlight weight, good elasticity and
quakeproof
Application:
cold preservation of freezing air conditioner and central
air conditioner
heat preservation of industrial pipelines
fireproof & heat insulation of civil buildings
damping, heat preservation and sun-proof of ships and
vehicles
industry beauty and decorating
sport apparatus, toys, boxes , etc. |
