What is PEEK 450G?
PEEK 450G Ultimate (unfilled) is our unmodified plastic product designed for motorsport applications. PEEK 450G provides a combination of properties which makes it a viable alternative to alloys in certain engineering areas. The material offers high-temperature resistance and excellent wear and abrasion resistance.
What is PEEK material?
PEEK material (polyetheretherketone) is a high-performance semi-crystalline engineering thermoplastic with outstanding harsh chemical resistance, very low moisture uptake, good fire performance, excellent mechanical strength across a broad temperature range, and good dimensional stability.
Is PEEK isotropic?
Olimunllum® CF/PEEK is a thermoplastic composite material containing a quasi-isotropic endless carbon fibre reinforcement and a semi-cristalline thermoplastic polymer matrix from the Polyaryletherketone (PAEK) family.
How strong is PEEK?
Its Young’s modulus is 3.6 GPa and its tensile strength is 90 to 100 MPa. PEEK has a glass transition temperature of around 143 °C (289 °F) and melts around 343 °C (662 °F).
Is PEEK expensive?
In a nutshell, PEEK’s ability to stay dimensionally stable under harsh environments makes it a highly sought after polymer. OEMs who use PEEK do so knowing well that for the properties offered, PEEK is unique and therefore expensive.
Is PEEK stronger than aluminum?
The inherent low specific gravity of VICTREX PEEK (1.3 g/cm3) is less than half that of aluminium and one sixth that of steel. This results in a superior strength-to-weight ratio so VICTREX PEEK-based compounds can offer equivalent strength and stiffness with up to 70% weight reduction.
Does PEEK absorb water?
Moisture absorption (also known as water absorption) is the capacity of a material to absorb moisture from its environment. Plastics with very low water absorption are polymers such as PEEK,PPS, PSU, PPSU, PEI, PVDF, PET, PPE, PP and PE. Furthermore, low water absorption is exhibited by POM, PA12, PC and ABS.
What happens after glass transition temperature?
There is a certain temperature(different for each polymer) called the glass transition temperature, or Tg for short. When the polymer is cooled below this temperature, it becomes hard and brittle, like glass. Some polymers are used above their glass transition temperatures, and some are used below.
Why is PEEK so expensive?
Why is PEEK So Expensive? While PEEK’s high temperature resistance can make it difficult to process, in its solid state PEEK is readily machinable by CNC milling machines. Filled grades of PEEK can also be CNC machined, but care must be taken to correctly manage stresses in the material.
Why is PEEK so strong?
Chemical resistance: PEEK displays high resistance amidst a wide range of chemical environments even in high temperature enviroments. It can only be dissolved in concentrated nitric acid or sulphuric acid. Long life: It is a hard, stiff and strong polymer. It displays good friction as well as wear properties.
