Advantage of heat conductive plastic 
led filament bulb 
comprison item aluminium heat conductive plastic
working quality product efficiency(lead time) middle short
processing temperature 700-750 260-300
mold life short long
equipment complex easy
need second time to process yes no
characteristic heat disspation factor 100W/mk 10W/mk
thermal radiation factor 0.1-0.2 0.8-0.9
toughness good good(24kj/m^2)
stretching factor good good(58Mpa)
insulativity bad(electric conduction) good(high pressure resistant>4000V)
environment protection recycling good good
environment protection bad good
Low-weight 40% lighter than Aluminum.
Mass-production ability The cycle time are shorten to 12 minutesper part.
High-desgin diversity Injection molding brings high designdiversity
Cost Down The cost can be cut down with mass production
Electricity-insulation The insulation treatment can be movedaway
