PEEK ( Unfilled )

The main properties of PEEK (Unfilled)  include:

● High mechanical strength, high temperature resistance, impact resistance, flame retardant, acid and alkali resistance, hydrolysis resistance, wear resistance, fatigue resistance, radiation resistance and good electrical properties.
● It has rigidity and flexibility, especially its outstanding fatigue resistance under alternating stress, which is comparable to alloy materials.
● It has excellent sliding characteristics and is suitable for applications that strictly require low friction coefficient and wear resistance. In particular, PEEK modified with a certain proportion of carbon fiber and graphite has better self-lubricating properties.
● It has excellent chemical resistance. Among common chemicals, only concentrated acids and alkali can dissolve or destroy it. Its corrosion resistance is similar to that of nickel steel.
● With a very stable polymer, 1.45mm thick samples can reach the highest flame retardant standards without adding any flame retardants.
● It has outstanding radiation resistance, surpassing polystyrene, which has the best radiation resistance among general-purpose resins.
● With excellent hydrolysis resistance, PEEK and its composite materials are not chemically affected by water and high-pressure water vapor. Products made of this material can still maintain excellent properties when used continuously in high-temperature and high-pressure water.
● With excellent insulation stability, it has good electrical insulation properties and remains to a very high temperature range.

PEEK (Unfilled)  is widely used in the following fields:

● Aerospace: PEEK’s high temperature resistance, high strength, wear resistance and chemical corrosion resistance make it an ideal material for manufacturing aircraft engine parts, aerospace vehicle internal parts, etc.
● Electronic and electrical appliances: PEEK has excellent electrical insulation properties and can be used to manufacture housings for electronic and electrical appliances.
● Biomedicine: Due to PEEK’s chemical inertness and low surface free energy, it can meet the sterility requirements of medical devices and is often used to manufacture medical equipment and parts.
● Marine Protection: PEEK’s corrosion and abrasion resistance enable long-lasting performance in marine environments.
● Automotive industry: PEEK can maintain good performance under high temperatures and chemically corrosive environments, so it can be used to manufacture automotive parts, such as gears, oil screens, shift starters, etc.
In addition, PEEK can also be used in the oil and gas industry, chemical industry, etc. If necessary, it is recommended to consult our plastics experts for more detailed information.
