PEEK physical property made by Smart Molding® method
Our developed Smart Molding® manufacturing process has contributed to further improve some properties of the high-functional resin super engineering plastic PEEK materials. And by our method which reduce waste, we can provide our products at a low price.
We show the values of the some physical tests for PEEK test pieces made by general injection molding and our developed Smart Molding, in the below.
• Comparison of PEEK physical property which made by general injection molding and Smart molding®.
|Unit||Injection molding||Smart Molding®|
|Flexural strength (at a rate of 2 mm/min)||MPa||145||170|
|Tensile break strength||MPa||77 (50mm/min)||81 (50mm/min)||100 (5mm/min)|
|Hardness (Shore D)||Hs||87||89|
|Coefficient of linear expansion
|Deflection temperature under load (1.80MPa)||℃||148.5||161.3|
Tested in March 5, 2015.
Tensile testing machine: Autographag-x plus-20kN manufactured by Shimadzu, Shore D hardness testing: In accordance with ASTM D2240, Melting point: X-DSC7000 manufactured by SII, Speciﬁc gravity: ME-33360 manufactured by Mettler, Coeﬃcient of linear thermal expansion: Apparatus of thermo-mechanical analysis TMA (Exstar TMA/SS7100/SII Nano Technology USA Inc.), Deﬂection temperature under load: Thermal deformation measurement equipment (Heat Distortion Tester HD-PC manufactured by Yasuda), Test samples: In conformity with ISO standards.
• The feature of KDA's PEEK
• In the tests, Flexural strength, Flexural modulus, Tensile break strength, the values of Smart Molding ® are higher than the general injection molding's.
• The value of Deflection temperature under load, the Smart molding®'s 161.3 degree is higher than the general injection molding's 148.5 degree. There is a raise of heat resistant temprature at the Smart Molding®'s.
The manufacturing process of our original method "Smart Molding®" is differ from generaly injection molding's. So as a feature in case of thin parts, our products are hard to warp.
