Tepla? PPS offers excellent chemical corrosion resistance, creep resistance, low water absorption, dimensional stability, high elastic modulus, flame retardancy and other properties; Tepla? PPS also has remarkable mechanical strength and rigidity, superior to general engineering plastics. Because of its superb heat resistance and high flowability, it provides convenient conditions for modification. Therefore, to make up for the natural defects of this material, we usually modify it to achieve its most ideal properties.
