Tensile yield strength is the maximum engineering stress in psi (or Pa) at which a permanent non-elastic deformation of the thermoplastic material begins.
Yield point is the first point where the specimen yields, where the specimen's cross-sectional area begins to contract significantly, or where the strain can increase without increase in the stress.
Ultimate tensile strength is the maximum stress the thermoplastic material can withstand before failing, whichever occurs at the higher stress level.
Total elongation at failure of some polymers:
|ABS||5 - 20|
|Acrylic||2 - 7|
|Epoxy||4 - 5|
|HDPE||700 - 1000|
|Polyamid (Nylon) 6||30 - 100|
|Polyamid (Nylon) 6/6||15 - 300|
|Phenolic||0.4 - 0.8|
|Polypropylene||100 - 600|
|PTFE||250 - 350|
