PEEK can be welded using standard methods such as ultrasound and friction welding, although it is important to take the high melting point of the material – 343°C – into notice when choosing the joining method. PEEK is hardly auto-combustible and readily self-extinguishing. The material is classified V0 and generates little smoke. PEEK complies with the RoHS directive. Peek can be glued using a variety of adhesives such as cyanoacrylate, epoxy and silicone. PEEK is resistant to almost all organic and inorganic fluids. The only known medium that will dissolve PEEK is concentrated sulphuric acid. The material is also affected by smoking, concentrated nitric acid.
PEEK is widely used in industrial applications. The mechanical attributes as well as the chemical resistance and food approval make PEEK particularly well-suited to: bearings, cogs, screw wheels, hydraulic parts, pump components, wear rings, and scrapers to severe loads, and for applications in the chemical and food industries.
Mechanical attributes of PEEK:
- Hard-wearing, with good friction attributes
- Extremely high dimensional stability/inherent stability, as well as bend and tensile strength – even at high temperatures
- High rigidity
- High creep fracture strength
- High temperature resistance, continuous (working temperature between -60°C and 250°C)
- Extremely high resistance to both X-ray and gamma radiation
- Elevated chemical resistance
- Excellent hydrolysis resistance
- Good electric and dielectric attributes for standard quality
PTFE features a variety of versatile attributes in a single solution
By mixing additives such as glass, carbon, graphite, bronze and stainless steel in with the virgin PTFE, we can tailor the attributes to match specific production environments and industries.
With PTFE and high-tech plastic as our area of expertise, we have the capacity to analyse complex issues and develop customized PTFE compound for your application.
