1. Main performance
Melting point: 334 degrees Tensile strength: 97.38MPa Bending strength: 134MPa
2. Main physical properties
1. Heat resistance
The long-term continuous use temperature evaluation method, the UL temperature index measurement value is 250°C.
2. Chemical resistance
PEEK only dissolves in concentrated sulfuric acid and has good chemical resistance.
Some test results are shown in Table 1: Table 1 Chemical resistance of PEEK (under 500kg/CM2 stress)
