Within the polyamides, commonly referred to as “nylons”, we distinguish different types. The most important ones are: PA 6, PA 66, PA 11 and PA 12. The differences in physical properties which exist between these types are mainly determined by the composition and the structure of their molecular chains.

The Ketron® PEEK family of materials is based on polyetheretherketone resin. This semi-crystalline advanced material exhibits a unique combination of high mechanical properties, temperature resistance and excellent chemical resistance making it the most popular advanced plastics material.

Ketron® PEEK is often used to replace PTFE when higher mechanical load bearing capacity, or when superior wear resistance are needed. Ketron® PEEK is widely selected as a replacement for metal components.

Main Characteristic

• Very high maximum allowable service temperature in air [250 °C continuously, up to 310 °C for short periods of time]
• High mechanical strength, stiffness and creep resistance, also at elevated temperatures
• Excellent chemical and hydrolysis resistance
• Excellent wear and frictional behaviour
• Very good dimensional stability
• Excellent resistance to high energy radiation [gamma- and X-rays]
• Inherent low flammability and very low levels of smoke evolution during combustion
• Good electrical insulating and dielectric properties [except for Ketron® HPV PEEK and CA30 PEEK]

Applications

• Pump components
• Valve seats
• Bearings
• Rollers

Acrylics generally have good optical clarity, scratch resistance, dimensional stability and rigidity. They do not deteriorate in sunlight and they have good adhesion, are thermoplastic, easy to form and easy to cut. However, they are combustible, are not flexible, suffer from stress cracking and are not resistant to solvents.

Acrylics have a very wide range of uses in the construction industry:

Applications

• Transparent or translucent sheeting such as acrylic glass (‘Plexiglass’ or ‘Perspex’)
• Opaque cladding and panel materials
• Resins, sealants, adhesives and adhesive tapes
