What is PEEK plastic?
PEEK (abbreviation for PolyEtherEtherKetone) is a high performance semi-crystalline, engineering thermoplastic.
PEEK Plastic Applications
PEEK is used in some of the toughest plastic applications that require the tightest tolerances. These include medical device parts, medical implants, structural applications, ultra-high vacuum applications, valve seats, pump gears, high purity seals, electrical connectors, screws, impellers, wear blades, lab equipment, analytical equipment, columns, cable insulation, and more.
Properties of PEEK plastic include high temperature performance, excellent wear properties, superior chemical resistance and outstanding toughness and strength. It also has excellent deformation under load characteristics, a high flexural modulus, and exhibits low smoke and toxic gas emissions when exposed to a flame.
In its solid state, PEEK is readily machinable by CNC milling machines and is commonly used to produce high-quality plastic parts that are thermostable and both electrically and thermally insulating. PEEK is often considered a superior high-end engineering plastic, in the same category as Delrin, PTFE or nylon.
General-purpose grade PEEK is unreinforced and offers the highest elongation and toughness of all PEEK grades. It is a strong and stiff plastic material that is often used in applications where performance at elevated temperatures is required, such as autoclaving. Peek meets Mil P 46183. It can be used continuously to 480°F (250°C) and in hot water or steam without permanent loss in physical properties.
Unfilled PEEK has been approved by the FDA for food contact applications since 1998.
PEEK is naturally a very light brown or tan color as displayed in our images below, and is also available in black. Since it is an engineering plastic, color variations may occur between batches.
PEEK plastic sheets are the perfect choice for any high-tolerance, high-heat, chemical resistant plastic requirements, no matter how large or small!
