PEEK Machined PARTS
PEEK Machining -SENTINEL PLASTICS machines bespoke PEEK Parts to customer specifications, samples or drawings. Our plastic CNC machine shop specifically caters for industrial plastic materials such as Peek.
Known for being a high performance engineering thermoplastic.
The term PEEK is an abbreviation for polyetheretherketone, the various grades of PEEK offer good chemical and water resistance, and can operate at high temperatures.
An attraction of PEEK is it can be used continuously to 480°F (250°C) and in hot water or steam without permanent loss in physical properties.
For use in hostile environments, the material PEEK is a high strength alternative.
Another plus point of PEEK is it carries a V-0 flammability rating and exhibits very low smoke and toxic gas emission when exposed to flame.
Unfilled PEEK is approved by the FDA for food contact applications
PEEK in Brief
- Excellent chemical resistance
- Very low moisture absorption
- Inherently good wear and abrasion resistance
- Unaffected by continuous exposure to hot water or steam
Types of PEEK
Standard PEEK Machined Parts made from general purpose Unfilled PEEK is not reinforced and offers the highest elongation and toughness of all PEEK grades.
But PEEK material is available in the following colours:
- Light brown (Natural colour)
Black PEEK is ideal for instrument components where aesthetics are important, as well as for seal components where ductility and inertness are important.
Unfilled PEEK grades comply with FDA regulation.
30% Glass Filled PEEK
30% glass filled PEEK parts have an increase in flexural modules and a reduction in expansion rate.
This grade is ideal for structural applications that require improved strength, stiffness, or stability, especially at temperatures above 300°F (150°C).
Glass-filled PEEK is only available a light brown colour.
30% Carbon Filled PEEK
30% carbon filled PEEK parts have enhanced compression strength and stiffness, and a dramatically lower expansion rate.
It offers designers optimum wear resistance and load carrying capability in a PEEK-based product.
This grade provides 3½ times higher thermal conductivity than non reinforced PEEK — dissipating heat from the bearing surface faster.
Carbon-filled PEEK is black in colour.
