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.

PEEK PERFORMANCE

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.

The Main Properties of PEEK

MACHINING PEEK

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.

PEEK GRADES

（1） Description:

PEEK（Polyetheretherketone）is a kind of heat-resistant, high performance thermoplastic special engineering plastics. It has good mechanical properties and chemical resistance, abrasion resistance, and hydrolysis resistance properties etc.; it has a light proportion and self-lubricating properties. Guangzhou Engineering Plastics Industries (Group) Company, has studied and applied this material in many industries for many years. Due to very good processing properties, it can be filled with carbon fiber, Fiberglass and MoS2 etc. In order to improve lubrication performance and mechanical strength further.

------PEEK-1000

This general purpose grade is unreinforced and offers the highest elongation and toughness of all PEEK grades. The newly available black PEEK 1000 is ideal for instrument components where aesthetics are important, as well as for seal components where ductility and inertness are important.

------PEEK GF30 (30% Glass-Reinforced)

The addition of glass fibers significantly reduces the expansion rate and increases the flexural modulus of PEEK. This grade is ideal for structural applications that require improved strength, stiffness or stability, especially at temperatures above 300°F (150°C).

------PEEK CA30 (30% Carbon Fiber-Reinforced)

The addition of carbon fibers enhances the compressive strength and stiffness of PEEK, and dramatically lowers its expansion rate. It offers designers optimum wear resistance and load carrying capability in a PEEK-based product. This grade provides more thermal conductivity than unreinforced PEEK -- increasing heat dissipation from bearing surfaces improving bearing life and capability.

------PEEK HPV (Bearing Grade)

Carbon fiber reinforced with graphite and PTFE lubricants, our newest grade of PEEK offers the lowest coefficient of friction and the best machinability for all PEEK grades. An excellent combination of low friction, low wear, high LPV, low mating part wear and easy machining, make it ideal for aggressive service bearings.

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!——Contact us?
