peek polymer
PEEK polymer are widely regarded as the highest performing thermoplastic polymers with good retention of mechanical properties over a wide range of temperatures and conditions.
TENSILE PROPERTIES
The tensile properties of peek polymer exceed those of most engineering thermoplastics. Tensile performance was evaluated according to ISO 527 and a comparative tensile plot of unfilled peek polymers . These unfilled grades show ductile behavior with a yield point of approximately 5% elongation and a tensile strength exceeding 14,000 psi.
Adding fillers increases strength and stiffness for a range of PEEK compounds.,Filled compounds typically do not exhibit a yield point and therefore break in a brittle way. Tensile modulus, strength and elongation vary significantly depending on the type of filler and filler content.
PEEK polymer are used to form structural components which experience or continually operate at high temperatures. demonstrates a good retention of mechanical properties over a wide temperature range.
FLEXURAL PROPERTIES
PEEK polymer exhibit outstanding flexural performance over a wide temperature range. Flexural strength was evaluated according to ISO 178,As for all semi-crystalline polymers, flexural strength of PEEK polymer is temperature dependent, with a pronounced step-change going through the glass transition (Tg). Even so, values of flexural strength of filled materials can achieve in excess of 29,000 psi at temperatures above Tg. The improvement in flexural strength retention in these graphs is explained by the increasing Tg going from PEEK polymer.
COMPRESSIVE PROPERTIES
Compressive strength was evaluated in accordance with ISO 604 at temperatures up to 480°F. compressive strength versus temperature for a range of Victrex materials with focus on grades typically used in wear and extreme high pressure applications, and unfilled PEEK 450G as reference.
CREEP PROPERTIES
PEEK polymer have outstanding creep resistance and may sustain large stresses over a useful service life with little time-dependent deformation. Creep is defined as the deformation observed versus time under a constant applied stress. Tensile creep was evaluated according to ISO 899 at 73°F over a period of 1000h.
