Performance Benefits
- very high fracture strain/fracture toughness does not fail even at
85-90% strain)
- very high strength (compression loading of up to 64 ksi shows
no failure)
- high temperature capabilities (useful temperature is over 450° F)
- machinable (can be sawed, cut threaded, sanded, or ground)
- low rate of thermal expansion °F in
flow direction)
- controllable pore size (from, e.g., a few microns to a few mm)
- easily bonded to other components (including metals)
- very smooth surface after grinding or polishing
- moisture absorbance < 0.1%
- low mold shrinkage
- solvent resistant
- fire retardant
Other Benefits
- save over 50% in material cost and weight
- processing technique (non-solvent) is environmentally friendly
- short processing time (4 hours as compared to weeks)
- thermoplastic makes it recyclable
