Heat-resistance
PEEK has a higher glass transition temperature and melting point (334℃). It is one of the reasons that it can be a reliable application in the requirement of the heat. Its heat load variable-temperature can be 316℃, continuous
use temperature is 260℃.
Mechanical Properties
PEEK is the plastic that strikes a balance between toughness and rigidity. Especially, it has an excellent fatigue resistance against alternating stress that is the most talented of all plastics, and it can be comparable with alloys.
Self-lubricating
PEEK has outstanding sliding characteristics in all plastics; it is suitable for stringent requirements for low coefficient of friction and resistance to friction used. Especially, the self-lubricating properties of PEEK will be better if it is modified by carbon fiber and graphite mixed in the proportion of each of them.
Chemical Resistance
PEEK has excellent chemical resistance. In ordinary chemicals, it can be dissolved or damaged only by concentrated sulfuric acid; its corrosion resistance is similar to those of steel and nickel.
