Product Description

Product parameters

PEEK is a kind of heat-resistant, high performance thermoplastic special engineering plastics. It has good mechanical properties and chemical resistance, abrasion resistance, and hydrolysis resistance properties etc.; it has a light proportion and self-lubricating properties.

Heat-resistance PEEK has a higher glass transition temperature and melting point (334ºC). 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 316ºC, continuous use temperature is 260ºC.


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.
 

Hydrolysis Resistance

PEEK and its composites will not be affected chemically by water and high-pressure steam. The products that are made from this material will maintain the outstanding characteristics in continuous use in high temperature and high pressure water.

Certification 

Companies strictly enforce the ISO9001(2008)international quality certification system, the product quality conforms to the eu RoHS standard.
