sulphuric acid China

...PEEK plastic raw material is a chemically inert compound that does not dissolve at room temperature in any traditional solvents, except for 98% sulfuric acid. Its solubility in water (at room temperature) is 0.5 mass percent. Its elasticity modulus is close to that of dense human bone, but not entirely equal to it. The melting temperature of PEEK is 334 °C, the crystallization peak temperature is...
