General comparision of polymer properties
 
Please read below to get a general idea, it generally shows key property classification for most polymers.
 
1.) Key property rating 
 
Rate Heat deflection Tensile strength Unnotched Impact resistance
-- (°C)          Polymer grade                 (Mpa)       Polymer grade               (Kj/m2)    Polymer grade
Highest  >300 CF / GF filled PEEK   >200 CF filled PEEK / PAI  >NB Pure PPSU / PC (Notched >50)
Higher 200-300 CF / GF filled 120-200 CF / GF filled     NB Pure High performance polymer
High 150-200 Pure or reinforced 80-120 Unreinforced 70-NB Unreinforced
Good 100-150 Unreinforced 50-80 Unreinforced 20-70 CF /GF filled
Low <100 Unreinforced <50 Unreinforced <20 CF /GF filled
 
Remark:
This is general classification, speical individuals are not specified.
 
2.) HDT (Heat deflection temperature)



 
3.)Tensile strength



 
4.) Unnotched impact resistance



 
5.) Notched impact resistance
